@atomicpoet @fediversenews I did further testing of all the iOS apps I’ve tried:
Mastoot: works with Friendica and Akkoma but not Pixelfed.
Metatext: works for Akkoma and Pixelfed and partially for Friendica (for some reason the federated timeline won’t load).
Toot!: works with Akkoma, works partially with Pixelfed (only the home timeline is accessible), but does not work with Friendica.
Woolly: works with Pixelfed but not Friendica or Akkoma.
I’ve yet to find one that works with Calckey.
