## Upgrade Base → Pro

In the console open **Subscription**. **Upgrade to Pro** swaps your existing Stripe subscription — it does not open a second checkout.

## Manage billing

Use **Manage billing** on Subscription for payment method, invoices, or cancel (web / Stripe).

## Apple subscription (iOS)

The AI Twin **iPhone companion** (invite only) can sell **Base** through the App Store:

| Product | Plan |
|---------|------|
| `aitwin001` | Base monthly |
| `aitwin002` | Base annual |

Manage or cancel Apple subscriptions in **iPhone Settings → [your name] → Subscriptions**.

**Pro** stays on the web console (Stripe). Pro in-app purchase is not available yet.

See [iOS companion](/guide/ai-twin-owners/ios-companion).

## Legacy Speak To billing

If your email matched an existing Speak To subscription, billing may show as linked legacy. You keep the same relationship while using the Theta console.

## Free trial

New twins get a trial period. When it ends, subscribe (web or Apple Base on iOS, if you have the invite-only app) to keep the twin online.
