BrainBoost is free with daily limits. Premium is an auto-renewing subscription that raises those limits and unlocks more features. Current prices are on the Pricing page.
Upgrade on the web
- Sign in first. Web purchases are tied to your account, so guests are asked to sign in.
- Open the upgrade screen from any Premium prompt, or from Profile.
- Choose Weekly, Monthly, or Annual and tap Continue.
- You are taken to Stripe Checkout to pay. Premium turns on as soon as payment completes.
Upgrade on iPhone
On iPhone the same plans are bought through Apple and charged to your Apple ID. Prices may be shown in your local currency.
Manage or cancel
- Open Profile, then Settings.
- Under Plan, tap Manage subscription.
- On the web this opens the Stripe customer portal, where you can cancel or update your card. On iPhone it opens your Apple subscriptions.
Canceling stops the next renewal. You keep Premium until the end of the period you paid for. Deleting the app or your account does not cancel an Apple subscription; cancel it in your Apple ID settings. You can also email thebrainboostsupport@gmail.com with the subject "Cancel Web Subscription" for a web plan.
Restore a purchase
If you bought Premium and it is not showing, sign in with the same account you paid with, then tap Restore purchases in Settings or on the upgrade screen.
Credit packs (web)
On the web you can also buy a one-time pack of AI credits instead of a subscription. A pack never renews. One credit equals one flexible AI use.
See how much you have used
Profile shows a usage panel with the percentage used for each feature today. Premium AI also shares a generous monthly fair-use budget, and the usage panel shows how much of it you have used.
