BEFORE YOU FLY Short breathing and grounding exercises you can do at the gate, guided by voice. IN THE AIR A calm button on every screen, always one tap away. Guided sequences for take-off, turbulence and landing. And plain explanations of the sounds that worry people the clunks, the thumps, the change in engine note, written by pilots who make them every day. AFTER A short log to note how the flight went, so the next one starts from a better place. IT WORKS WITHOUT A CONNECTION Everything you need in the air works in flight mode. No signal, no problem.
