What is the most legit app to make money?

Hello there, I'm curious about finding a legitimate way to make some extra cash through an app. With so many options available in the market, it's hard to distinguish between the genuine ones and the scams. So, I'm wondering, what would you say is the most trustworthy and reliable app that can genuinely help me earn some money? Ideally, it would be something that's user-friendly, has a proven track record, and offers a decent earning potential. Can you shed some light on this?
