Not precisely, they weren’t 1-for-1 clones. But when I moved from Android to iOS I was easily able to adapt to Apollo from Sync. Very similar visuals, very similar gestures, similar developer devotion.
Sync was not only my favorite app for reddit, but IMO the best UI/UX of any app I've ever used. I enjoyed Connect until Sync came out, but now that it has I feel like I can finally enjoy Lemmy as much as reddit. Everyone will have their preferences and prices they're willing to pay, but $20 absolutely seems reasonable to me for how much I use it lol.
