Personally, for custodial LN, I like Wallet of Satoshi. Sets up fast and is easy to operate in under a minute. Be sure to setup with your email for backup and restore to use on any device.

Phoenix Wallet (by ACINQ) is a lightning node in your pocket. They have a beta out now for their next generation that may be worth waiting. Their current version is good too, but this next version aims for 1 channel to ever be created.

Breez , but haven’t spent enough time with it yet.

I’m also testing Mutiny, which uses HTTPS, that operates within any browser. It is in Beta, so wouldn’t recommend yet as your first choice.
