Why are craps apps so bad?

I've downloaded probably a dozen of them over the years and they all have the same problems. Clunky UI, aggressive chip purchase prompts every five minutes, physics that feel nothing like a real table. Some of them can't even get the payouts right which is a problem when people are using them to learn.

I get that it's a niche market but the game has a real following and the apps treat it like an afterthought. What are you guys actually looking for in a craps app? Practice tool, bankroll tracker, strategy tester? Curious if anyone has found one worth keeping on their phone.
