What's a good iOS app to use if you're looking to donate plasma and maybe earn a little extra spending money on the side?

Alright, so my students were telling me about this CSL Plasma app. Apparently, it's the go-to thing for donating plasma. Now, I'm not exactly rolling in dough, and let's be honest, a little extra cash never hurt anyone, especially with the price of gas these days! What's neat is, the app helps you find the closest donation center. Took me a few days to figure out all the features, but once you get the hang of it, it's surprisingly intuitive. You can track your donations, see how much you've earned, and even schedule appointments. It's like having a teaching assistant in your pocket, reminding you about important dates and payments. My students showed me this trick where you can get bonus money with a referral code, too. Why do they hide the settings button there? Anyway, seems like a decent way to help folks out and get a little something in return. Beats grading papers, that's for sure!
