App terms.

The app license

For the App Store release, we use Apple’s Standard End User License Agreement. Apple provides this standard license for App Store apps when a developer has not supplied a custom license. This page is an informational overview and does not replace that agreement or your applicable consumer rights.

What the app is for

Review available pulse readings, mark moments yourself, and try Hot Seat questions. A bluff or tense-moment label is a report you choose. In the sensor-free Truth or bluff game, the reveal shows the storyteller’s declared selection and is not independent verification. Nubi’s expressions are part of the interface, not an assessment of your body or your answers.

The app does not detect lies, determine truth, diagnose stress, or provide medical advice. Readings may be sparse or unavailable. A pulse change has many possible causes and should not be treated as proof about another person or as a basis for medical decisions.

Your choices

Participation, sensor access, answering questions, and sharing an invitation are optional. Anyone can skip a question or stop a round. If someone else wears your Watch, choose the guest option and let them decide whether to take part.

Before sharing, review the invitation image or text and choose its destination. Sharing does not send pulse readings, dates, question text or private answers. Local recovery keeps only the latest successfully saved checkpoint and cannot restore unrecorded time or guarantee every session survives an interruption. See our privacy policy for the full data and deletion details.

Availability and support

The app is available on the App Store for a one-time upfront purchase of US $0.99. There are no subscriptions or in-app purchases. Local prices may vary. It is designed for a compatible Apple Watch running watchOS 10 or later, with no iPhone companion app required.
