I'd like to start getting into app development, solely to solve some problems of my own, rather than to make money. I have 2 ideas for, what I think, are simple apps. One is a sort of form app that fills in data and generates a completed, printable document. The other is essentially a slideshow app that uses the Unsplash API to turn my ipad into a digital picture frame when it's just sitting on my desk and I want to look at pretty things.

I have 0 experience with programming languages other than tweeking some existing jquery from time to time. Where should I look to learn how to make these apps? Free or premium services are fine. I feel I learn best by watching and imitating rather than reading and trying to figure it out.
