EasyCT

This app was developed for people, who wants to be motivated in being remembered of the own clean time. It also shows the achievements in form of chips and coins that they receive.
As well, there are also implemented reminders for "small" birthdays, such as for entire months or funny day numbers, even if there are no chips or coins meant for it, cause every clean day is worth a celebration.

The reminder function also works with added friends so that you neither forget their clean time birthday.

The app is self-explanatory, but here's a little tip: you can also click on the chips and coins and see what happens.

Have fun!
