How the estimate works

Glidey compares wind at two altitudes along the great circle from NOAA's public GFS model, on your iPhone. It is an estimate with an accuracy score (AUC) of 0.71, not a flight forecast. Pilots and airlines make the real decisions.

  • Smooth
  • Some bumps
  • Bumpier

Turbulence feels scary and is almost always only uncomfortable.

Planes are built to handle far more than the air gives them.

Reassurance card: Bumps feel big, but the plane is built for them

Questions

Is it a forecast?

No. It is an estimate for planning and reassurance.

How far ahead does it work?

Up to about 5 days before departure, the range of the weather model.

Does it work offline?

It needs a connection to load wind data. Breathing works without one.

Which languages?

English, Deutsch, Español, Português, Français, Italiano, Japanese, Korean and Traditional Chinese.

Is my data private?

Yes. Glidey has no account, no analytics and no ads, and your trips stay on your iPhone.
