What's a good Android app for filling those little downtime moments with something that might actually earn me a bit of extra spending money?

Oh, I've been exploring Swagbucks Play Games + Surveys, and it's been quite a delightful discovery! As a retired librarian, I appreciate a well-organized system, and this app is wonderfully organized. I can fill those little moments – waiting for the tea to steep, or perhaps during a commercial break – by playing games or answering surveys. And the best part? You earn points that can be redeemed for gift cards! I figured out three new features this week alone; who knew my phone could do this? It's like having a little card catalog of earning opportunities right in your pocket. The categorization system is brilliant, allowing me to quickly find the types of activities I enjoy most. I must say, it’s quite impressive actually, especially for someone like me who enjoys a bit of structure and the potential for a small reward.
