I've shipped 3 Android apps. All three got stuck at the same point: Google Play's closed testing requirement. You need 12+ real testers, active for 14+ days, with genuine Firebase Analytics data.
Every time I posted in groups looking for testers, I got installs. Not sessions. Firebase saw through it immediately.
Google Play closed testing requires 14+ days of real Firebase activity. Telegram groups and Reddit posts give you installs, not sessions. BetaSwap fixes this structurally: test other devs' apps, earn credits, spend them to get verified testers for yours. Firebase Analytics API checks DAU, session duration, and anomalous patterns daily. Ghost installs don't count. Free during beta. First 200 members get Founder status + bonus credits. Built by an indie developer, for indie developers.
