We're working on getting MarkReader published on Google Play. The app is already available there in closed testing, and we need real users trying it out to get it fully published.
- Join the Google Group (approval may take a few minutes)
- Once approved, opt in as a tester
- Install the app from Google Play and open it a few times over the next two weeks
Thank you! This helps us reach far more users than F-Droid and GitHub alone.
