Koos 🆗 is a user on octodon.social. You can follow them or interact with them if you have an account anywhere in the fediverse.
If you don't, you can sign up here.
So on iPhone 5 the Mastodon web UI is quite miserable in Safari.
BUT
when added as a homescreen bookmark it is way better (faster, stabler, intuitive) than Amoraq. Best web app experience I have had so far.
Bonus: saved logins for multiple instances!
Just found out that it is quite useless on Federated - every time a toot is added, the scrolling position changes.
@koos I was having this trouble earlier. If you scroll down just a bit, the auto scrolling stops. No more jumping toots!
