I love that the data that I put into this stays on my phone and doesn't get uploaded anywhere. I love that the creators of Euki don't have access to my data and they don't sell it. This app is very convenient to use and it is good at predicting my next period. I also like that you can track things like sexual activity and discharge. It helped me realize that what I was experiencing was just my body cleaning things out after my period. I'm no longer worried about it. I do wish it had more moods.

I generally love this app. It's simple to use, private, and has never given me any issues. However, today I noticed that the calendar is messed up. September and November are missing and instead I have two Octobers and two Decembers. It isn't a huge deal. The months are still separated and the days are numbered correctly, the months are just labeled wrong. Regardless, I'll continue using this app, as I appreciate how reliable and accurate it is.

I think this is a bug but I can't track anything after June 7 2025. If I backtrack to that date from the calendar or the dashboard I can add symptoms, but after that it just brings me to a date slider that seemingly sets you back to Jan 1, 2013? The date slider is further confused by not listing the year. when you try to add things after June 7 2025, you get brought to an empty screen with a 7 day date scroll at the top and if you scroll all the way to the end it ends at Jun 7 2025. What do I do
