3 APPS in 1: Period Tracker, Personal Diary, and Calendar. We designed Day After because we wanted an app to not only track our periods, but to also track our daily life and events. We also wanted it to be beautiful, fun & simple to use.. that which gets more personal and intimate the more you use it.

As a period tracker app, we knew it had to be very accurate. So we had done extensive research and used an algorithm based on multiple period cycle data to calculate and predict future periods and fertile days. We have also included a basal body temperature tracking system with beautiful interactive charts so that you can more accurately predict your ovulation.

A weight tracking system is also built in so you can track your weight changes over time and view them on a graph. We also added wide variety of stickers so you can mark days with things like moods and symptoms. The stickers you add are easily viewable without having to flip to another screen.

We thought that the app would also be a great place to store private thoughts and memories. So we built in a full featured diary with photos and stickers. Daily photo albums is a great place to store all the photos you take every day. We also wanted to share some of the photos/notes with friends and family, so we built in sharing.

Knowing when our next period is going to be has the advantage of scheduling certain events... Maybe you want to schedule a vacation trip but don’t want it to fall on your period? So we thought we should build in a full featured calendar with events.

We also built in alarm reminders into the calendar so you can be reminded even if the app is not running. We included a suite of event stickers so that you can decorate your event so that it is easily identifiable at a glance.

We designed the app to use for ourselves and we hope you love it as much as we do! We’d also love to hear your feedback!

Two boys with this app!

It’s a fun and helpful app to keep track of cycles. I’ve told all my friends who were planning on growing their family.

Almost perfect

This app needs an Android option. I had to use one of those for three weeks and I was devastated that I could not use this app on that device.
This app needs an updated website. It is frustrating to be able to find almost zero information about this app online. I LOVE this app and I’m not the only one. I want to know this app is supported and loved.
I agree about the need for increased flexibility of period length. I had a thyroid issue and needed to be able to note that I was having ‘mini periods’ but sometimes I wasn’t able to accurately add them because I couldn’t add a new period too close to a previous one.
I need to be able to sync this app between devices in a more reliable way. Sometimes it moves data between phones and sometimes it does not. A better profile feature would allow for that? I’d pay for it.

Extend period glitch

I like this app, but it’s always been a bit glitchy (for example, if I try to add more than a few stickers or notes, it will crash), but now it’s got an intolerable glitch: it won’t give me the option to start a new period, only extend one from January! I’ve taken to just noting when my period starts and ends, but this is stupid.
