Yesterday I submitted the first "public" build of MastoBlaster to Apple, and it is now under review. Once it's approved, I'll share the link with a few people for testing and gradually expand the beta as we go.
The goal is to provide a public beta to the entire Fediverse before the official release, so everyone can try it out. I've already been using it as my primary app for several days and, aside from a few bugs I still need to fix, it’s working well.
Stay tuned!
