Molarity Ltd operates on a subscription-based model with monthly billing. Access to the full 73-station bank and AI-powered OSCE sessions is determined by your chosen tier.
| Tier | Price (Monthly) | Voice Session Quota |
|---|---|---|
| Free | £0.00 | 5 Sessions /mo |
| Basic | £11.99 | 50 Sessions /mo |
| Premium | £17.99 | 150 Sessions /mo |
Subscription quotas (the number of voice sessions allowed) reset on your billing date every month. Unused sessions do not roll over to the following month.
If you exhaust your quota mid-billing-cycle, you can upgrade to a higher tier immediately through Molarity Ltd. The difference will be pro-rated for the remainder of the month.
All payments are handled securely via Stripe. Molarity Ltd does not store your credit or debit card information. By providing payment information, you authorize Stripe and Molarity Ltd to charge the monthly subscription fee until cancellation.
You may cancel your Molarity Ltd subscription at any time through the Settings > Subscription screen in the app or via the Molarity Billing Portal. Upon cancellation:
