I have a specific idea, but I don't know here to start
Hi! My 25 year old daughter has had Type 1 Diabetes since she was eight years old. I used to create all kinds of tools for her on paper to track her finger poke sites, injection sites, meals and blood sugars. Since then she has used apps for better control, but they are always lacking in one way or another. I would like to build a logging, tracking, goal/reward based app using avatars and a room as the base for the reward system. I have in depth knowledge and a first person resource for what would be useful to an app like this, but I don't know which language I need to learn. I learned HTML4 with a For Dummies book back in the early 2000s to build websites, so that's as much coding knowledge as I have (aka not much), but I did successfully teach myself with the book, so I feel like this is something I can learn to do with a little direction. Thanks for any help and advice :)
