Google's requirement for new personal accounts: 12 testers continuously hold the app in a closed track for 14 days. Google counts continuity per tester — so everyone joins at once: 12 required and 3 backup enter the track on day one. One of the fifteen drops out — the "12 continuous" requirement is still covered.
Describe your app — the 12+3 package is the default: a minimum of 12, and the cap is yours to choose.
Testers apply with track-ready emails. The whole squad joins the track at once — 12 required plus backup.
Progress is visible every day: who's in the track, who's slacking, who dropped out. The developer confirms participation against the console.
Someone drops out — the "12 continuous" requirement is still covered by the backup. The countdown doesn't restart.
Google counts 14 days of continuity per tester: someone joining on day eight starts their own clock from zero. That's why backup testers enter the track from the start — one dropout doesn't break the "12 continuous" requirement.
Nothing at the start. Testers earn karma and developer rewards. Paid packages will come as the platform grows.
A list sells emails and vanishes together with its guarantee. The platform holds testers for all 14 days: participation confirmation, −15 karma for an abandoned track, a day-one backup.
