For 60 minutes you can earn sats but it randomly decides the amount, this can often times be zero. I generally get 1-3 sats a minute on days when it is working, although I've had the rare 25 sats a minute.

There's also sometimes a promotional podcast and ad that gives you a few extra.

I've also had it not give me anything for three weeks, but that eventually fixed itself so.... 🤷

But I do use it.
