Every sound you hear after takeoff.
Most fear comes from sounds you don't recognize. The app explains them the moment they happen, before you even ask.
- T+00:00
“The engines roar and I'm pressed into my seat.”
Takeoff thrust is set. The aircraft will reach about 250 km/h in roughly 30 seconds. This is exactly what should happen.
- T+00:35
“The nose suddenly lifted up.”
This is called rotation. The pilot raises the nose to about 15 degrees, the same on every takeoff.
- T+00:45
“A heavy thud came from under my feet.”
The landing gear retracted into the fuselage and the doors closed. Loud sound, ordinary event.
- T+01:30
“The engines got quieter. It feels like we're falling.”
The pilot reduced power from takeoff to climb setting. The aircraft is still climbing, your inner ear just reads it as a drop.
- T+03:00
“A whirring from the wing, then a slight sinking.”
The flaps are retracting. The aircraft is now fast enough that it no longer needs them.
- T+18:00
“Ding, ding. Did something happen?”
A routine chime between the cockpit and the cabin crew. Usually it means the seatbelt sign just went off.
Turbulence feels scary. The numbers aren't.
Calmfly measures every bump in G with your phone's sensor and shows you where it sits on the real scale.

Questions that keep you up at night.
Can turbulence bring a plane down?
Airliners are certified to withstand at least 2.5G, and the wings are tested to one and a half times that. Everyday turbulence stays far below. Nearly all turbulence injuries happen to passengers who weren't wearing a seatbelt.
What happens if an engine fails?
Twin-engine airliners are designed to take off and fly to the nearest airport on a single engine. Pilots practice this scenario regularly in the simulator.
Why do the wings bounce?
Wings are built to flex. A rigid wing couldn't carry the load. Flexing is how the aircraft absorbs turbulence.
Is a go-around dangerous?
No. A go-around is a standard safety maneuver pilots choose when landing conditions aren't perfect. The app shows how likely one is before you land.
Does Calmfly replace therapy?
No. Calmfly is a support tool that stays with you during the flight. If your fear of flying affects your daily life, we recommend talking to a professional.
