The Android app is ready. The Play Store listing isn't.

ShootOS on Android is finished, and it's the same app your iPhone crew uses — but it's still going through Google Play's testing programme, so it isn't public on the store yet. Leave your email and we'll send you a tester link so you can install it today.

We add your Google account to the tester list. Usually within a few hours — it has to be the account signed in on your phone, or Play won't show you the app.
You get a link. Tap it, then tap “Become a tester” and “Download”. Play installs it like any other app.
Sign in with the same email you use on the web, and you're running.

Don't want to wait? ShootOS runs in your phone's browser right now — no install, same account. On iPhone the app is already public: get it on the App Store.
