1. Erli Bird is a website where you can earn money by becoming a beta tester for new apps, websites, and products. You only earn $10 after you follow all the instructions for giving feedback so this is not a side hustle that will make you rich but every little bit helps! If you are in the top 25% of testers, you can earn an additional $5. So far I have earned $20 for reviewing two apps and I am the process of reviewing a gaming app now!
