I found nostrich to be incredibly slow and buggy.
Also the whole thing felt like a cheap vibe coded app, the kinda app that only gets made to stop people from using an existing better program
Testing it right now. Didn't connect to relays at first but now it works. I like it cause it looks clean and intuitive to use. Regarding 'buggy and slow': so far I feel it is not that bad but def behind Damus on iOS and Amethyst on Android. Image upload is a bit slower. App opening a bit slower too. Doesn't feel buggy tho. So far.
