User reviews

Thank you!

I appreciate that the user can enter their own terms for the habit and duration, compared to another low-frills, low-telemetry app Onrise (also good and I really appreciate developers who put their work out with such a low barrier to entry. If I make software, I will give it away, too- the potential for good is huge).
Maybe this is a bug- tapping the gear icon, then tapping Close without changing anything, removes the entry fields and pushes the three buttons (Save, Close, Remove habit) to the top of the screen, with no apparent way to get back other than rebooting the app (the buttons are unresponsive). iPhone xR

Finally

Let’s start with I have ADHD and no matter how cute the games are or the points I score - the other apps have not gotten me any closer to success. I am also not going to ever sign into a tracking app every single day, I mean I can’t even find my keys daily or remember important appointments soooo. This is shown in a week and I just click on the day I did it. No pressure. no steak. no points. no cute animals houses growing. Just look at it and click when I did it or didn’t.

AND IT’S FREE. LEGIT FREE. Please don’t make it to where I edit this review to remove this part in the future. I am all for the apps that accept donations or do like a “subscribe for a few dollars to support our creators”

Love it

I’ve gone through so many habit trackers. They’re usually very busy and colorful, which isn’t bad, but I just couldn’t focus with all the extra options and features. This habit tracker is simple. I like that you can choose how many days of the week you want to complete a task and you have a green filled in bubble when you complete a task. Would definitely recommend.
