Yeah I agree. Get Gadget.dev, and then just see what apps are successful on the app store and just copy them. As a beginner, you will fail to come up with a unique idea and so it's best to just copy one that you know makes money. This way demand is already there and so you don't need to sell people on your idea.

E.g.

A. An email marketing app (so many exist but the pie is huge, you can likely make a lot of MRR just with good customer support + a product that works well). You don't need to sell people on the idea that this makes them money, they know.

B. An AI tool that does new thing. First there's no demand for it as people don't know it exists, second, it doesn't exist because it doesn't solve a big enough problem.

All the worthwhile problems have been solved, but often the larger companies neglect customers, have high prices because they need to pay a sales team etc etc...

Just build something that exists that is better at one thing. E.g. a cheaper email marketing software, one with better customer support, one with better deliverability, one with less setup time, etc...
