I'd say text inputs are notoriously hard/cumbersome to emulate/re-implement in order to match the native control behavior/functionality. I guess your app doesn't depend that critically on it? (unlike messaging app)
Just curious, how much time do you think you put into it in total? App / web
Also curious how you marketed it, if at all
I'm monetizing only through subscription. I made it part of my mission to refrain from all ads and focus on privacy as much as possible. For the next version I have removed Firebase Analytics and Crashlytics as well.
The subscription for my app is half as expensive as the one from other apps on the market. But there is a rather hard point where you kinda have to buy PRO. That's if you want to track more than 15 stocks.
I put in around 1000 hours so far.
