I have. Nothing bad to say about it. I have Stack and Unstoppable installed, probably going to keep Stack.

Im trying to figure out why its not more popular.
Because it supports shitcoins. They do have a Stack Duo wallet which is just BTC and Monero. Stack Duo is somewhat popular among the more open minded Sovereign Bitcoiner types.
Yes stack duo is what i was interested in. I like that I can get it with Obtainium. Not easy to find a wallet without the Play Store.
Weird, I hadn't heard of Stack Duo until or was mentioned but when trying to add it to Obtainium it "can't find a suitable release".

try turning on "include prereleases" and it should work
Because it's relatively new to the scene. But it's great, I recommend it - my main wallet right now. Open source, non custodial, and privacy oriented. Diego "Rehrar" is behind it. Pretty well known person in the Monero community.
