The latest update on github for the iOS app is 4 to 5 months ago. Is this app still maintained ? Are there any alternatives which are maintained ?
Why do you think it is not maintained ? Latest Pull Request is 23 days old.
So to answer your question, yes, it is maintained.
Whilst it is maintained, there is unfortunately a shortage of iOS developers, so it has some longstanding bugs (losing connection, images not updating) and limitations (video and map widgets not supported)
Everyone can do a pull… a merge is activity to me. But if there is a shortage in devs that would explain the long list of bugs.
