When you need extra money, I discovered that there are many money-making apps that work in different ways.

The sweet start was with survey apps - Swagbucks and Survey Junkie give you money for answering questions and watching videos, but the money is a bit slow.

Then I tried freelancing through Upwork and Fiverr - here, the money is better if you have skills in design, writing, or programming.
Many people earn good money from here.
If you want to sell old stuff you have, there’s nothing better than eBay or Etsy for handmade products.

Other things that work:
Rakuten and Ibotta give you cashback on regular shopping, meaning you get money from your purchases.
Uber and DoorDash if you want to work in delivery or transportation.

But the most important thing - not all money-making apps are equally efficient.
Choose based on your time and skills, and check reviews before you start.
Some people make real money from money-making apps, but it requires patience and consistent effort.
