Ratings and reviews

Pretty straightforward app that can be used as an habit tracker or as a symptom tracker, for example. But app suffers from many usability issues and really dumb UI choices. Dev provides many updates but so far I'm not really liking the way it evolves. Paid from premium and no regret but not sure I'll keep using it

trying to display a payment for every months because it's reacuring payment I need to be reminded, but on premium it still the same ,I have to enter it in every month by hand, this is a general feature, it not on premium, waist of money, premium no difference from standard, please update features, and I will update my review.

Love the app, but first time I see an app that it only works for 7 days "free trial" after that the app basically does not work... I think that should be changed so people can still use the app with limited features but the core functionality should be free...
