What was free now is “pro”

I have been using the app for a couple of years now and it has always been free. I love the app but I was sad to see that the free version changed its layout completely and well, for worse. To stay with the old layout I had to pay for the “pro” version which is basically what the app looked like before the massive update. For that I’m knocking one star off the review; otherwise the app is great.

Crashed after I updated my phone software to ios14.2. The developer doesn't offer an option for communication: just frequently asked questions, which doesn't cover requests for updates. 🙄
Pity, I have been using this app for years and was very happy with it! ❤️

The same developer offers now a different app, where you are supposed to SIGN IN ( tracking in a period diary app is fishy!) , and offers fitness and diet advice - basically, Marketing, probably selling stuff! 🙄
