Trying Voyager now, installed the app on my android via Firefox. It's nice and simple and I really like the look and feel of the UI, both when posts are compact and large.
My only complaint, which is true for all the FOSS Lemmy apps, is that the appearance settings, really all settings, are global for the app and not based on the account you are browsing with. That is the one nice feature of Sync that is stopping me from sticking with any of the FOSS apps. Having my account on lemm.ee open straight to All Communities with compact posts and NSFW blurred, while having my ...other Lemmy account.. open straight to Local Communities with large posts and no NSFW blurring is a really nice feature of Sync.
I'm always looking for an android keyboard that is either only a number pad, or can be configured to show the number pad first by default. I have this one use case, playing farkle mostly, where I like to split screen excel and an image of the rules, and because excel is open split screen the keyboard always opens to letters. It drives me nuts that I cannot force a keyboard to open to a number pad.
