This app is a scam. They hold a “drawing” every 15 minutes where you can “win” 50-75 cents. The catch is that to cash out, you need to get up to $15. Spoiler alert: you never will. You’ll win a bunch of times the first few days. Then, the closer you get to the cashout threshold, the less frequent those wins will become. Eventually, you’ll stop winning altogether.
Also, they’ll send you a push notification each day claiming that (some number >20,000) people won that day, and “many” cashed out. They do 96 drawings per day, and each one has 30-50 winners. That’s a nope in the math department.
Bottom line, they’re just seeing how long they can con people into watching ads that will give them revenue. Download it if you must, but don’t say I didn’t warn you.
