Looks good! I'm using HabitBull[0] for past few weeks, and it's not bad, but i like your approach, so i'm going to give Grow a try.

Few random notes after first minutes in the app:

- i made a typo in the habit name and couldn't find a way to edit it

- it would be useful to have an option to check the relevant days for each habit (eg. only mondays, exclude weekends, …)

Thanks! Regarding your notes: I am planning on fixing editing but I am not sure about setting a specific day. I can see a reason on doing so but I am assuming (also basing on the research) that habits are behaviours performed daily. But again this is something I heard from other people so I guess I will give it a bit more deeper thinking.

Can't install on my Xiaomi Mi 4.

What Android API features does this app use that are not available on the Android version I have installed?

Which Android version are you using? I am not using anything extraordinary, Room, Support Library and Design Library as external dependencies.

Android Version: 4.4.4 KTU84P

MIUI Version: 7

You are using API 19 where minimum API level is 21. The 21 is used because I am using Vector Assets Generator.

Very similar to Forest - Stay Focused in mechanism

I wasn't aware of "Forest" - even tho it looks similar in a way of "rewarding" the concept of the app is different. "Forest" has this reward mechanism developed a lot better tho.
