Are there any real money apps?

I'm curious, are there any legitimate mobile applications that allow users to earn or manage real money? With the growing popularity of cryptocurrencies and digital finance, I've noticed a plethora of apps claiming to offer financial opportunities. However, it's difficult to discern which ones are genuine and SAFE to use. Can you provide some insight into the legitimacy of these apps and perhaps suggest a few reputable options for managing and potentially growing my finances?
