Atomic Wallet was one of my first phone app wallet I have installed and have been using. The first benefit using the wallet was that they were airdroping their native currency AWC. On the other hand negative experience was with XRP as you have to have balance at least 20 XRP which are non withdrawable. They have also high fees. The app overall is simple and easy to use. One the big advantage is they are providing staking for selected crypto (AWC 20 % APR). You can also buy and exchange crypto. Worth to mention it is non custodial wallet.
