During the holidays I found a few faucets that are Android apps. In case you are brand new to this concept, faucets are places that allow you to get small portions of cryptocurrency for free. Well, almost free. You have to visit the site, sign up, and often perhaps solve a captcha.
In return, the faucet will let you retrieve a small amount of cryptocurrency from time to time. Each faucet will set up its own payout schedule and quantity -- usually very small quantities.
Many faucets are a bit clunky. Perhaps they are run by a single person who understands exactly how their site works but does realize that you or I don't. This can be a bit frustrating and you may just decide to avoid some of the faucets as it isn't worth hassling with anything for something usually worth a small fraction of a cent.
However, apps generally don't require a captcha as your phone will have already authenticated you! That doesn't eliminate advertising but it can eliminate captchas.
I'll write up a review of these apps soon...
