E6B flight calculators

Crabwise is an E6B-style flight computer for study and preflight planning. It runs entirely on your device: no account, no tracking, no ads.

In the app

Each result shows the formula and the numbers behind it, the way you work it on a paper E6B.

No account, no signal needed. Crabwise is for training and reference; always cross-check with approved sources.

  • Not for navigation — training and reference only.
