This was just announced today by @blockbrothers! (the witness I am part of).
Within the next two weeks, we will be upgrading the Steemify production servers to prepare for the upcoming releases of Steemify for Android (v1.0) and the new version of Steemify for iOS (v1.6) read more here.
It's been a long time coming. Fantastic!
Android users will soon be able to find Steemify in the Google Play Store and iPhone users will find some new cool features in their update.
One of the features: the implementation of mute lists. No more notifications from accounts that you don't want to have.
Ow! and if you haven't heard about Steemify before:
Steemify is the best iOS app (and soon Android) to get notified about anything regarding your account or the accounts of others on your phone.
