How credits work
Free includes one app. Pro is $20 once, adds 100 credits, and uses that balance for further generation.
Free and Pro
Free includes one app generation, preview and testing, publishing on a Nyravi address, and bug and deployment fixes. It does not use a credit balance. Pro is a one-time payment of $20 and adds 100 credits.
What the balance is for
On Pro, generation uses the credit balance. Account shows what is remaining and what has been used. Additional packs are 220 credits for $40 and 600 credits for $100. Credits are added after the payment succeeds.
When the balance is finished
The projects stay where they are. The preview and the chat are not removed because the balance reached zero. Add a pack from Pricing & Plans or from Account, then continue in the same project.
What Pro adds besides credits
Pro also includes further products, new features in the project chat, source-code download, a custom domain, and native mobile builds. Those controls appear in the project when the account is on Pro.
