Freewallet is the best wallet developer. They got their wallets as web wallets, Android apps, and even AppStore apps. Speaking of the Monero Wallet especially, I'm using it as an Android application.
It works pretty well: without any lags or bugs, no issues for a year or so. However, I used to contact the support once: when they asked me to enable the two-factor authentication. Had a minor problem with this but I did realize that it was for my own safety. It secured my funds and made me less nervous.
Also, I like the ability to set my own fee for the transactions: I can speed up them or on the contrary, slow down.
