I want to make a productivity app based on Jerry Seinfield's Don't break the chain productivity secret [1]. I have noticed that there are several apps for it already available on android but most are underwhelming in my opinion. Features like viewing friend's progress or sending gift to encourage progress would be features I want to include.
I don't have android application programming experience as I usually program in C/C++ and lisp. So this will be my first app. What do my fellow hacker news readers think of this idea? Would you use it? Would you consider paying 1-2 dollars for it if it's good enough? What kind of features would you want in it? Do you think it's worth pursuing for the experience and maybe some earnings?
