Apple has made it a little easier now to become a beta tester for the farmOS Field Kit iOS app. Now all you have to do is go to this link and follow the instructions to install Test Flight, if you haven’t already, then Field Kit:
If you’re on Android, you can install the beta version here: https://play.google.com/store/apps/details?id=org.farmos.app
One more way you can try it out, is with the Field Kit progressive web app (PWA), which you can find at https://farmos.app.
It’s still not fully stable, but getting more so by the day. If you have a chance to let us know what you think, post back here at the forum to document your experience.
