iOS or Android. If iOS, you could try freefrom, from the playstore or you could try freerse. They have a TestFlight build of that one but I’m not sure if it’s newer or the same as the App Store version.

If Android, I have only heard people use amethyst, so I don’t know of any other you could try.

You can always do what I did when I first found this place. I went through all of the clients and figured out which one I like best.

For me, nostr:npub1yzvxlwp7wawed5vgefwfmugvumtp8c8t0etk3g8sky4n0ndvyxesnxrf8q blows all of the others away but there is a lot to load so I probably wouldn’t recommend trying it until you’re on WiFi, so you can get the best experience.

Try those first two I mentioned, they are very minimal, and go from there.

Cheers.
