Tap "Download for Android". The ARCK.apk file saves to your phone.
Open the file and, if asked, allow installs from this source. That prompt is normal for any direct download.
Launch ARCK, sign in, and jump into your first match. Your camera does the rest.
Yes. ARCK installs straight from this page like any app outside the Play Store, so Android shows a routine "allow this source" prompt — that's standard, not a warning about ARCK. There are no ads, no hidden charges, and your camera is used only to count reps. Tap Install anyway and you're in.
