Good to know.
Are AirPods required?
No. On supported iPhones, TrueDepth can still measure viewing distance. Compatible AirPods add head-tilt information.
Does Noddi record me?
No. Sensor input is processed on device. Noddi stores only the resulting measurements in your local diary.
Is this medical advice?
No. Noddi provides general wellness estimates, not a diagnosis or replacement for professional medical care.
Can I delete my history?
Yes. Delete individual entries inside the diary. Removing the app also removes its locally stored data.
