Ikura Period Tracker Is Available on TestFlight

Ikura means “fish Roe” in Japanese.

About a month ago, the internet was full of “delete your period tracker now” posts. So I decided to check out what the popular period trackers are doing and make an app that does the opposite: Ikura is a period tracker that’s private, discreet, and secure.

I don’t have periods, and I’ve never used a period tracker, so let me know if I said something stupid.


Privacy First

I never understand why period trackers need your personal information to function. Or why that information needs to be uploaded to a cloud server. Most people probably want to keep their menstrual cycles to themselves, so Ikura doesn’t collect any data or require an account to use.

Also, you can use the app without an internet connection because it never makes any network requests. Think of it as a good old paper calendar, except Ikura is more secure.

You can import your data from the Health app. Ikura doesn’t export data to the Health app in case you’ve previously granted access to your health data to some “wellness” app.


Discreet Design

Ikura doesn’t look like a typical period tracker app. Instead, it somewhat masquerades itself as a calendar app to avoid attracting attention. It’s not pink and doesn’t use 🌷 flowers or ❤️ hearts in the UI, so you won’t feel uncomfortable using the app in a public place. There is no big header showing “next period in x days” to deter strangers from peeking at your screen. It doesn’t even mention “period” in the app.

You can also set the code words for period, menstrual cycle, and fertility windows.


Security Stuff

Ikura basically treats your data as if they’re passwords. The entire database is encrypted with SQLCipher. The encryption key is stored in the Keychain.

You can (and should) set a passcode to unlock the app.


It is Free

Ikura will be free, with no in-app purchases, no ads, and no tracking. You can sign up for the beta if you want to help test the app.
