I started off using Voyager, swapped to Mlem because of slight differences I preferred. Recently found out Thunder for Lemmy is available on the apple appstore and it instantly became my favorite. I like how unique the ui is compared to other, it seems better suited for browsing and posting on Lemmy, while the others feel better for the initial transition from Reddit. Very suprised it has barely any downloads or reviews when its easily the best Lemmy app on IOS.
Thunder reminds me of the more “modern” alternative front ends for lemmy some sites have while mlem and voyager feel more like the alternative reddit apps (blue alien) and give a similar experience.
On desktop, I’ve been using Friendica.
I use sync occasionally, and I found it has some features literally no other app has (or I’m too dumb to find them) like easy instance switching. It’s right there on the main screen, you just click instances, pick a federated instance, and boom, now you’re seeing stuff from that instance. I wish more apps has that.
