Any alternative to photographic films?

I'm just an admirer of pinhole photography. I was very impressed by the recent post on this sub. I'm making up my mind to do my own pinhole photography. Could y'all please answer the following questions? 1. Is there a way to do pinhole photography using smartphone camera? 2. Is there a way to use photographic films without having to do all the nasty chemicals treatments ( basically, without getting my hands dirty)?
