What caught my attention in this Reddit post is the pattern: small apps built around one specific hobby. The people using them already care about that hobby, spend money on it, and want tools that fit their world. Teaching moment: When you’re looking for an app idea, pay attention to what people repeatedly do, ask for, or struggle to find. A focused solution for a real community can be more useful than another app trying to serve everybody.

What’s a hobby you're into that still doesn't have a good app?
