I use to be a big phoenix user. Keeping around 2-3 millions SATs for all my weekly purchases with Bitcoin. 

When they chickened out the US I tested out Mutiny and Zeus. 

Mutiny did not work well for me. 90% of the time the payments would not work. 

Zeus worked a little better, like 50% of the time it worked. But it takes a long time to open. And 50% is not enough. 

I decided to just download back the APK version of Phoenix on Obtainium and that's it. Fuggem all. 

I like the guys from Mutiny and I know Zeus are working hard too, but it just ain't working right now.
