Support
Need help with Calmer Sky? This page explains how the app works, what it measures, and how to get in touch.
How Calmer Sky works
Calmer Sky uses your iPhone’s built-in sensors to provide a calm, measured view of movement during flight.
- Place your phone flat on the tray table.
- Keep the phone still while measuring.
- Use the readings for perspective only.
- Always follow cabin crew instructions.
Does it need Wi-Fi?
No. The core movement monitoring and calming tools work offline, so you can use Calmer Sky during your flight without an internet connection.
What does it measure?
Calmer Sky measures movement experienced by your device. It does not measure aircraft performance, aircraft altitude, flight safety, or turbulence forecasts.
Privacy
Calmer Sky is designed to be privacy-first. Movement readings are processed on your device and are not sent to us.
