Mutual Testing Community for Developers
A community platform where app developers help each other test their apps. We solve the challenge of "I can't find testers" and "I need people to participate in closed testing" through developer-to-developer collaboration.

Simple Credit System

◆ Test another developer's app → Earn 4 credits
◆ Post your app for tester recruitment → Spend 20 credits
◆ Test 5 apps, recruit testers once—a fair system

If you actively participate in testing, you can recruit testers for your app completely free, as many times as you want. If you're busy, you can purchase 20 credits for $5.

Premium Membership for More Convenience

At just $9.80/month, premium members get:
✓ 40 credits automatically every month (enough for 2 postings)
✓ Testers earn 5 credits when testing your app (normally 4 credits)
✓ Your recruitment posts get priority visibility

Premium apps offer higher rewards, so testers gather faster.

Fair Display Algorithm

To give all developers equal opportunities, listing order is determined by:

Priority display for apps with tester shortage

Boost period for newly registered apps

Random elements that vary rankings each time

Preference for small recruitment numbers

New and veteran developers alike can fairly acquire testers.

Perfect For Developers Who:

✓ Need Android closed testers
✓ Use Google Play Console's closed testing track
✓ Want to find bugs before launch
✓ Need real user feedback
✓ Want to join a tester community
✓ Want to connect with fellow developers
