By the way. Gab now has apps on both app stores.

Here's the one I am using on iOS: https://apps.apple.com/gb/app/tootdon-for-mastodon/id1282283934

How to use: enter in Gab.com for the instance domain. Sign in with your Gab email and password.

You can discover other apps by searching "Mastodon" or "ActivityPub" on both App Stores. A few of them have blocked Gab's domain, but many of them work.
