best pomodoro app ive tried

This app is the best pomodoro app ive ever used. It has very cute layouts and the pomodoro technique is great on this app, you can see daily rankings in your region as well as upload photos of your studies. Moreover, you can set goals and if youre a premium member even timetables. You can also look at your letter ranking, how many breaks you’ve had AND it has sounds you can tune to. Eg: rain and bonfire. Overall amazing app with amazing features. Ive probably forgotten so many more features because of how many this app has.

useful and cute!

Hi! I began using this app last month-- and I love it! It's simplistic in nature and the designs and colors are so cute! What I love most about this app is that you can track in detail your studying patterns and times, which is really helpful to me as a student! I haven't loved a productivity app so much in a while, which is why I'm giving 5 stars 💕💕💕

But there are a few bugs/things to fix: though my language is in English, my notifications are in Korean; the app sometimes crashes on me; the timetable sometimes glitches. Since this app is quite new, I'm sure it will only get better!

Some features I would love to see: a better time selection feature-- I want to be able to assign specific days in a month; planned study time goals showing up on the timetable; monthly/weekly rankings; more characters to type for the goals!!

Ty for flip, I love Itt
