Earn money just by walking around! No location data needed, just steps/health data. No smart watch necessary - can use the pedometer in your phone! Not truly passive, since you have to click "claim" and watch at least 1 ad every day, but really pretty solid. I'll be keeping this one in my main stack. You can get around 10-20 cents per day depending on how much you walk and how many ads you wanna watch. Minimum withdrawls are also pretty solid offering as low as $1 Amazon giftcards that you can pretty reliably get within the first 24 hours of having the app.

• Enable sleep points to increase points by around 30-50% (off by default, opt-in). Guaranteed 2 cents passive inc per night, without ad boost
• Avoid the stupid tree watering mini game. it takes like over an hour to get the tree fully grown and you get about $1.80 from it
• do the "smile" and "meditate" and "breathe" side quests for easy guaranteed points. Looks like about 1-2 cents per ad watch for these ones. Once daily.
• boost earnings with watching ads, if you want. up to 2x earnings on steps and sleep, potentially.
