Bluewallet is a Bitcoin and Lightning wallet for iOS and Android. It is the most user friendly Lightning wallet i have come across so far which will be important in the future for Bitcoin and Lightning adoption, because not everyone wants to run a node.

Features tested so far

Lightning Sending and Receiveing

My only negative at the moment is that when refilling your lightning wallet it doesn't deduct the fee so if you want to send the whole contents of your BTC Bluewallet to Lightning you have to estimate the fee and deduct it before you send. This is no reason to not download and use Bluewallet so far i'm impressed.
