Birthday reminders for the whole family

Everyone loves birthdays. They represent milestones in our lives and mark our transitions from childhood, adolescence, adulthood, and the golden years.  Remembering someone’s birthday is a good way to let them know that you’re keeping them in your thoughts. With an extended family, or an extended social group, it can be difficult to keep track of everyone’s special day. It’s also difficult to make sure that everyone in the family remembers each other’s birthdays.

Cronote is proud to announce that we now support yearly reminders. This makes it easy to schedule birthday reminders, up to 10 years in the future!  The feature can be accessed from the New Reminder dashboard by clicking on “Recurring” and selecting “yearly” from the repeat drop-down as seen in the picture below.


Here we’ve scheduled a reminder for our aunt’s birthday on February 6th. It’ll go out on Feb. 6th 2017, 2018,…all the way to 2027. The power of Cronote is that we can send this same reminder to every member of the family. We can create a family group, and schedule set it as the destination of our reminder.


You can add and remove family members to this group whenever you like. The reminders will go out to the current members of the group when her birthday arrives.

Cronote Reminders iOS App Now Available

full_iphone             app_store

We removed our iOS app from the App Store about a year ago in order to rebuild it in a modern fashion. We’re happy to announce today that the app has been released and is available for download on the App Store.

The app provides free push-notification reminders between iOS devices. It’s the only app that lets you schedule a push-notification.

The app also includes a number of features requested by our users, including:

  1. Message templates: Store commonly used reminder messages.
  2. Message variables: Automatically insert the recipient’s name and appointment time into the reminder.
  3. Recurring reminders: Send reminders daily, weekly or monthly.
  4. Group reminders: Easily select more than one recipient, and save groups such as a family or customer list.
  5. Picture reminders: Add an image with message overlay to make a memorable reminder.
  6. Reminder offsets: Schedule reminders relative to an appointment time. For example, “20 minutes before appointment” or “1 day before appointment.”
  7. Easily add a picture to your reminder using your Photos library or your camera.

We encourage all of our users to download the app and try it out.

Alternative to Google Calendar SMS Notifications

About a year ago, Google Calendar stopped supporting one of its popular features — SMS notifications. This feature remained available to customers of Google Apps for Work, Education, or Government.

For those not in those categories, Google suggested two alternatives:

1.  Rely on smartphone notifications from the calendar app that came with your device

2.  Install the Google Calendar app onto your device and use its smartphone notifications

We’d like to suggest a third option:

3.  Use Cronote Reminders to continue scheduling SMS notifications

Our service allows you to continue sending text message (SMS) notifications if you prefer/need them over smartphone notifications. With Cronote, you’re also able to schedule SMS notifications to be sent to other people, something that smartphone notifications are unable to do.

At this time, we do not offer Google Calendar integration; that might be a feature down the road. In the meantime, we do hope to offer you this comparable alternative to Google Calendar’s long-gone SMS notifications.


Existing Text Message Services for Health

Earlier this year, the Annual Review of Public Health reported that the majority of text message interventions are effective in managing diabetes, weight loss, physical activity, smoking cessation, and medication adherence for antiretroviral therapy. The researchers had reviewed 89 individual studies published between 2009 and 2014.

There are many proven, federally-funded text messaging services for health. We found a nifty table by the U.S. Department of Health & Human Services, which we’ve reproduced below:





Maternal & Child Health

Providing pregnant women and new mothers free health text messages in English or Spanish, including information and referral timed to the stage of pregnancy or age of the baby; involves a public-private partnership with National Healthy Mothers, Healthy Babies Coalition and Voxiva; since February 2010, more than 650,000 people have ever enrolled in Text4baby


Child Health
(Nutrition & Physical Activity)

Providing a library of brief, evidence-based messages focused on nutrition and physical activity targeted to parents and caregivers of children ages 1 to 5, based on Bright Futures Guidelines, and available in English and Spanish; the messages can be disseminated through text messaging or incorporated in other programs


Tobacco Control

Delivering 24/7 tips, motivation, encouragement, and advice about smoking cessation through text messages targeted to adults and young adults; the service is free, but message and data rates apply


Tobacco Control

Offering a library of free and publicly available interactive text messages for adults who are ready to quit smoking; includes a delivery algorithm with day-specific quit messages that provide tips, motivation, encouragement, and fact-based information; message content can be tailored according to user-specific keywords

SmokeFree Mom

Tobacco Control

Developing a library of free and publicly available text messages for pregnant women who wish to quit smoking; the messages will be personalized, interactive, and evidence-based

Health Alerts On-the-Go

Health & Safety

Providing CDC’s health and safety information on mobile devices, including seasonal flu, H1N1 flu, public health emergencies, and other topics

Text Alerts Toolkits

Emergency Response & Prepardness

Providing a text message library for emergency preparedness and response for voluntary use by state and local agencies can use during hurricanes and floods; future topics include chemical, biological, radiological, nuclear, and explosion messages

There are likely many more since this table was published in 2014. Some public health agencies, like the Seattle King County Department of Public Health, even have a webpage dedicated to local text message resources.

If your local or federal public health department does not offer the text messaging service you need, you can create your own using Cronote. Cronote reminders can be easily adapted for health. The co-founders of Cronote are trained health professionals as well, so if your organization is looking to develop such an intervention, let us know. We’d love to help!

4 Text Messages a Week May Help Heart Patients

It’s been a while since our last post, but we’re happy to see a growing audience for Cronote!

A couple days ago, the Journal of the American Medical Association (JAMA) published a research study suggesting that semi-personalized text messages may help reduce heart disease.

The study was based in Australia through the Tobacco, Exercise and Diet Messages (TEXT ME) program. There were 710 participating patients, all of whom had a record of coronary heart disease between a given time frame (Sept 2011 to Nov 2013). The patients were split into two groups — a control group, which received usual care, and an intervention group, which received 4 text messages per week for 6 months (in addition to usual care). The text messages provided advice, motivational reminders, and support to change lifestyle behaviors. Similar to Cronote’s reminder system, the text messages were not interactive; that is, the patients could not respond.

At 6 months, patients in the intervention group had significantly lower levels of LDL-C (bad cholesterol) than those in the control group. Patients in the intervention group also had lower systolic blood pressure, increased physician activity, and reduced smoking.

This study suggests that text messages may have an added benefit to lifestyle changes.

At Cronote, we are motivated by scientific publications like these and encourage you to share with us how you are using Cronote. We hope that this article inspires you to think of ways you can use text message reminders to improve wellness and health for yourself, your family, and your friends.

Thinking of a special way to surprise your Valentine? Scheduled text messages is a simple, personal (and wallet-friendly) way to let your loved one know that you care. Send him or her notes throughout the day, and make it a Valentine’s Day they’ll never forget.

Cronote is a website that lets you to schedule text messages to be delivered at a specified time in the future. There are 3 easy steps:

  1. Select the recipient. (Enter your Valentine’s cell phone number or email address.)
  2. Write your message. (Suggestions: “Your smile makes my heart melt!” or “Can’t wait to see you tonight!”)
  3. Set the delivery time. (February 14, at various times throughout the day.)

If you’re feeling extra creative, you can integrate Cronote into a Valentine’s Day scavenger hunt. Hide gifts for your loved one. Then, schedule text messages to arrive at special moments throughout the day, telling him/her where to look. Watch as your Valentine lights up in surprise and delight each time a new message comes to their phone. He/She may look even more surprised if you are sitting right there and are no where near your phone!

Since Cronote messages are scheduled in advance, this will take some of the stress out of the day. Your Valentine will also feel special knowing that you planned ahead for this memorable day.

Nobody likes reminders

Last night we had a conversation with our co-founder’s brother, Steven. He works as a user interface / interaction developer in Southern California. I wanted to get his feedback on what we hoped to accomplish with our new system. I explained that our current reminder platform just isn’t working.

“Nobody likes reminders,” was a phrase that kept cropping up in our conversation. Well yes, reminders are a form of nagging and it can be upsetting when your memory lets you down. But does everyone dislike being reminded? That’s not true, in fact one of the best use cases for Siri is the “remind me to buy milk” scenario. Siri is incredibly quick. Less than 5 seconds to schedule a reminder. Cronote takes at least 20 seconds to open the app, choose a recipient, write a message, set a delivery time, and click schedule. The few times that Siri gets it wrong are worth the overall speed gain.

We know what we’d have to change to make Cronote successful – add voice integration, use the sender’s phone number, make text message reminders free. All of these are possible within limits, but the reality is – do we like reminders? Eh.

The Lean Startup philosophy of customer development is undermined if the founders aren’t interested in the product. You have to want to use your own solution. See Drew Houston’s (CEO/founder of Dropbox) application to Y-Combinator. It’s clear that he wanted Dropbox to exist for the world, for his family, and for himself. Excitement about your product fuels its development and helps you wade through the tedium towards product perfection. After all, if you’re not using your product, what do you care if it’s 15 seconds slower than it could be?

That deal of introspection came out a bit last night. What do I want Cronote to be? A reminder platform? No, that’s not it. How did we come up with Cronote? It’s a true story that my co-founder wanted an easier way to remind me to do things. I jumped on board because it was feasible and made sense – it should be easier to schedule a reminder for someone else. But did I actually want those reminders? Probably not. Would I use the app to schedule reminders for others? Hardly at all. Then why did I invest so much time in developing a web app and iPhone app? It was because I believed in a use case for Cronote that went beyond reminders.

I’m excited about the future. It’s the same excitement that drives people to Engadget, Gizmodo, and TechCrunch. I want to know what’s happening tomorrow, today. I believed that Cronote could provide insight into the future through its “reminder database” – with user permission, of course. Imagine if 1,000,000 people were reminding their spouse to “buy an iPad” next week and 500,000 were looking to “buy a Nexus 7.” The data would provide predictive insight into the relative success of the iPad vs. the Nexus 7. I was interested in making a predictive dataset through community contribution.

It was this vision that fueled the development of Cronote. Yet, the final product did not provide a compelling service to drive user adoption. We rarely use Cronote, so how could we expect others to adopt it? The lackluster growth of the Cronote website and the Cronote Reminders iPhone app forced us to look elsewhere for ways to build our future dataset. We went through a series of changes and ideas (Remind button, anyone?) that suffered from the same misconception – that you can make a product for others that you don’t use yourself.

It’s time for us to change our mindset. Forget about reminders. How do we get people to share their future in a way that we want to too? This is what we discussed with Steven. He asked some hard questions about our own habits and those of our intended audience. Selecting the young adult audience (we’re in this group), ages 18-35, what problem did Cronote solve? Here’s the gist of our conversation:

“We’ve been going with the new slogan, Share the Future,” I told Steven, “it’ll let people post what they will be doing.”

“That’s rather vague. Can’t they already do that on Facebook and Twitter?” Steven responded.

“Well, yes, but this will let them add a specific time in the future to their post. That way people can integrate the event with their own timeline.”

Steven wasn’t convinced. “Do people actually want to do that?” He contended. “What’s an example of something I would want to share on Cronote, but not on Facebook or Twitter?”

“Well, how about a business trip to San Francisco next week? That’s certainly going to be on your calendar, but not necessarily something you would share on Facebook or Twitter.”

“So I would make a post about my trip today and hope someone comments about it?” Steven said.

His tone implied a question – why would someone care to comment on my future trip? I responded hesitantly, “Yeah, and then maybe someone you know will also be in SF and ask you to hang out once you get there.” It wasn’t a strong response.

“What if nobody comments on it? A business trip doesn’t sound too interesting to post in the first place.” He said (paraphrased).

“It doesn’t have to be interesting, it just has to be in the future. It gives your friends time to comment on it as it gets closer to the date.” I said.

“So your system let’s me share future things that are not interesting in the hope of a coincidental common interest?” He said questioningly (again paraphrased).

“Well yes, I guess. Another example is the post, ‘I have to go get groceries tonight.’  You wouldn’t put that on Facebook or Twitter. But if one of your friends need groceries too you can organize a trip together.”

Our conversation went into some depth, but we hovered around this mission statement:

Cronote let’s you share what you’re going to do (whether it’s interesting or not). The incentive is that your friends might want to join you (e.g. ‘I’m going shopping tonight.’), encourage you (e.g. ‘I want to lose 5 lbs by next month.’), or ask you about it (e.g. ‘I’m retiring next year.’).

Not a very compelling charter, but would our target audience use Cronote if it fulfilled this mission? I can tell you I’m 10X more likely to post I’m going to get groceries tonight rather than scheduling a reminder to get groceries tonight. I’d never do the latter, I might do the former. Quantifying might remains our next challenge and I would greatly appreciate your feedback. Would you post what you’re going to do (whether it’s interesting or not)?

Cronote Rebuild

When we first started on Cronote we wanted a way to see the future unfold. Over time we pigeonholed ourselves into a reminder service that only lets you send/receive an email or text message at a future time. It’s great for scheduling reminders in advance, but it’s not quite what we originally had in mind.

We believe there is a need for a system that enables people to share upcoming events quickly. Think of it as a Twitter for the future. You see something you like next week, next month, or next year, and you can post that event on your timeline. Your friends can see that event and add it to their timeline or comment on it. Popular events provide insight into future trends and are highlighted based upon their number of reposts. Our goal is to allow people to participate more actively in each others’ future by providing a simple platform for event sharing in a timeline format.

We’ve decided to rebuild Cronote in order to achieve this goal. Our existing service will remain operational, and existing features will be built into the new application. Stay tuned for our progress updates and follow us if you’d like to participate in early testing.

Top 3 email and text message reminder web applications

There’s been a boom in web applications offering email and text message (SMS) reminders. When we started out two years ago the vast majority of these services could only handle email reminders (no text messages). Now there are quite a few services that offer both email and text message reminders. Much of this growth is due to low-cost APIs such as Twilio that enable easy computer-to-phone connections in software. Before Twilio it was rather difficult to interface an Internet application with the cell phone network.

This post takes a look at the current competitive landscape in the scheduled reminder arena. I like to think that it is as objective as possible, but I am obviously biased towards Cronote.

A quick (non-scientific) Google search for “schedule a text message reminder” reveals a whole slew of companies providing various degrees of functionality. Here’s a list of the top three results along with their features and pricing.

1. – We are not the #1 result, that honor goes to This site was created a long time ago, back before the Twilio API existed. They are the forerunner and have more or less maintained the same look and feel. Anyone can use their form without an account to schedule a quick reminder. Their form supports natural language processing as well so you can use phrases such as “now”, “today 3pm”, “tomorrow 8am”, without having to specify an exact time. If you are completely new to text message reminders, this can be a fun site to tryout. A premium account comes with many features including the ability to store contacts and schedule recurring reminders. Premium accounts cost $4.95 per month or $47.50 per year. All text message reminders are free, but ones not associated with a premium account have embedded ads and cannot use the full 160 characters. Ohdon’ does not allow users to create groups of recipients, and does not offer email text messaging.

2. – The second result is Whereas has the aesthetic of a slick Web 2.0 (3.0?) site, looks like a relic from the 1990’s. was also a forerunner to Cronote and provides bare bones features for scheduling both email and text message reminders. The service is completely free, but comes at a large usability price. There is no address book for storing contacts and you must know the carrier of the recipient in order to send text message reminders. There is also no ability to schedule reminders for more than one recipient. has a sister site, that enables anyone to schedule a quick text message reminder without signing up for an account.

3. – Cronote is the 3rd result! Our website is aesthetically in-between and We tried to strike a balance between minimalism and being informative. We require a free registration prior to using our service, a decision that was based on our desire to control spammers. Registered users are able to schedule email reminders for free. A major difference between our service and others is that we charge 5 cents per text message, rather than a flat monthly fee. We feel this provides a better value to our customers. Consider that a flat monthly fee of $4.95 ( equates to 99 reminders using our system. Most of our users schedule < 60 reminders per month (i.e. about 2 per day). Our service provides address book functionality that makes it very easy to schedule reminders for specific people. Another prominent feature of our service is the ability to send reminders to groups of contacts. This works incredibly well for families, coworkers, teachers and students, and any other group of people. Groups, like contacts, can be stored in our system for future use and can be modified at any time. Cronote is also the only service to offer an iPhone app that works in conjunction with our website. This makes it very easy to schedule reminders on the go. One drawback of Cronote is that our recurring reminder functionality is limited to daily repeating reminders. This is a feature we hope to expand on in the near future.

Here’s a summary table comparing the various features of these three reminder services:
