Loved by Developers Worldwide

Real feedback from people who shipped their Android apps with 12Tests.

I had been stuck in closed testing for three weeks with not a single tester. 12Tests had 14 people opted in before I finished making dinner. Production access came through nine days later.

The daily screenshot proof alone was worth it. I could show my partner exactly what testers were doing every single day, and Google never questioned the 14-day log.

We shipped our Android release in nine days from scratch. The feedback report caught two crash paths our QA completely missed. Enormous value for five dollars.

I was nervous about paying strangers to test my app. The dashboard made it transparent — I could see device names, countries and session counts the whole way through.

Google kept rejecting my questionnaire answer. Support actually helped me rewrite it and the approval came the same week. That alone was worth far more than the plan cost.

We publish monthly and this costs less than one coffee meeting. Testers are consistent, professional, and the reports read like they came from a real QA team.

Twenty testers found a battery-drain issue that only happens on mid-range Android. We fixed it before launch instead of after a wave of one-star reviews.

Started on a Friday night, testers were onboarded by Saturday morning. The 14-day clock started immediately and never stalled. Zero stress.
