Poker app for US players with iPhone.

I’ve been playing BOL but it’s a site and it’s too easy to accidentally close out the program. I like ACR but they’ve been talking about an App forever and it’s only talk.
I’m curious as to what poker site you guys think has the best app. I like play money, micros, $5 & $10 SNGs and tourneys.
Thank you for your replies.

if they use an android app you can get bluestacks for ios that runs android Apps..

betonline is your best choice it looks like. or maybe ignition? sorry i have zero knowledge about that one but maybe its worth a try? i heard they accept us players.
