When to use Karma
- You're an indie developer doing your first Closed Testing
- You don't need priority placement
- You want to test the platform before paying
170 Karma at signup is calibrated to exactly fund one full Campaign: 168 Karma goes to 12 testers × 14 days × 1 Karma per approved check-in, and 2 Karma is the platform fee. Once your app launches, you can earn back Karma by testing others' apps.
When to use T-Coin
- You want priority placement (paid Campaigns rank higher in the marketplace)
- You're running multiple apps simultaneously
- You're a Studio Owner buying extra seats (5,999 T-Coin per +13 seats)
- You want to give testers cash rewards instead of Karma
What stays the same between them
Internally the reward distribution algorithm is identical. Whether tester payment is in Karma or T-Coin:
- Each approved daily check-in pays the same per-tester base
- Level multipliers (C → SSSS, 1.00 → 1.30) apply identically
- Bonus pool is reserved for full-attendance testers
- Settlement happens at day 14 (or earlier if all testers complete)
The only behavioral difference is withdrawal: T-Coin can leave the platform as USD, Karma stays inside.
What it costs in real money
- Karma path: $0. 170 Karma = one full Campaign, free.
- T-Coin path: starts at $10 (1,000 T-Coin top-up). Platform takes 20% on Campaign publish; 80% goes into the tester reward pool.
There's no subscription. No monthly fee. You pay only when you publish paid Campaigns.
