I always recommend #IceCubes @IceCubesApp for iOS because it's just very nice overall and I never felt I was limited by it. I do not know about the spell check system, but it's free so you can just download and try it out!

I’ve been having trouble uploading videos to Mastodon mobile app for a couple weeks now so I decided to try a new client. I downloaded a couple and liked #IceCubes the best. It works really well and also it’s very aesthetically pleasing, and makes the Fediverse feel like a warmer place. (It does use #OpenAI to generate #alttext and as a writing assistant which I’m fine with but I know that’s a dealbreaker for some.)
