It doesn't need to become mainstream. I'll be happy to be a part of a smaller but vibrant engaged community. I hope there will be a phone app some day through
I’ve been experimenting with WefWef, which is a web app that works really well on iOS and probably works well on Android as well. Reminiscent of Apollo or Sync.
On iOS you can add it to the Home Screen and it acts like an app. I think you can do so on Android as well, but it’s been a couple years since I’ve used Android.
