Release
Release the app to Google Play and Apple's App Store.
Will likely only happen once version 1.0 is reached (which in turn should be this summer, i.e. before the race in September).
(Edit) Preview builds are available on F-Droid for you to try!
(Edit2) A release to the major public, i.e. on the App Store and Google Play will be delayed until ISA has had a chance to look at this app (and hopefully officially endorse it). This unfortunately means that although it is production-ready, a public release is unlikely to happen before the 2019 race :( Until then you can build it yourself, join the closed beta, or get it from the niche store F-Droid.
