How do these apps work? Mining on a phone? Is it Bitcoin? Doesn't make sense to me. 

Remember

I don't want to hurt you, but nothing is free when it comes to BTC, especially. You'll either be scammed or end up paying in some way (your privacy). Mining on your daily use devices is just false and it looks fishy to me.

Check out ember fund in the App Store 
Make sure to plug in my code we both get a boost when we mine together and I’m active daily

Hi everyone!
I use Grass and Slice on computer and Nodle on my IOS but I also have android.
Can you reccomend me something similar or even better I would be very thankful.
Also I use Freecash but where I am in EUROPE (Croatia) is not that much of a earning, I earned 10 euros in a month and now is hard to earn even a euro.
Every suggestion is good.
Thank you and have a lovely day/night.
