I know some of those are not open source at all, but non of them appear to be in F-Droid.
However, I see OBW (Open Bitcoin Wallet) is in F-Droid and it is a non-custodial, open source option! I'm not sure how it ranks with Google (or if it's even in their app store, since I don't want to have that one installed).
💩. Nevermind. OBW is no longer maintained. My bad.
And the only other lightning wallet currently in F-droid is in even worse shape: the source code was removed from GitHub! That one is BLW (Bitcoin Lightning Wallet).
I think the moral of the story here is that the first non-custodial lightning wallet that gets put into F-Droid will likely dominate that area of the market. Even a custodial one would probably mop up, at least for a while.
So if you are on a team that makes a FOSS Lightning wallet, you might want to mention this to the rest of the team.
