If you're looking for easy ways to earn extra money, there are many apps that can help you. I personally tried several money-making apps, and some of them are really worth the time.

First, apps that give you money for surveys and simple tasks - Swagbucks and Survey Junkie are well-known in the field. But honestly, the money isn't usually much, though sometimes there are nice tasks worth doing.

If you have a specific skill, you can go to Upwork or Fiverr. There, people pay real money for services - design, writing, programming, everything. Money-making apps of this type are much better than surveys.

Regarding selling, eBay and Etsy are good if you have old items or handmade products. Also, Rakuten and Ibotta - these give you cashback when shopping, so it's like you're earning extra money while you buy.

As for Robinhood and Acorns, these are more for investing rather than simple money-making apps - but if you're thinking long-term, they might be good options.

There are also Uber and DoorDash if you're looking for actual work. But it's important to choose what suits you and read reviews before starting - not all apps work equally well in every area. The money-making app that fits you depends on your available time and your skills.
