Landing-field awareness on your wrist — which fields you can reach right now, given your glider, the wind and your height.
GlideRange turns your Garmin watch into a glide calculator and landing-field awareness tool. From your position, height and your glider's best glide ratio — corrected for the wind — it shows which of your landing options are within reach right now, each with its distance and the glide ratio it needs. The crucial information stays on your wrist even when your glide computer has switched to a thermal screen.
You load your own outlanding fields and airports from a .cup file with the free GlideRange uploader, so the app carries no built-in dataset to go stale and works in any country. How many sites fit depends on your watch's memory — the uploader shows the limit for your specific model before you sync. In flight, a per-site screen points a direction arrow at the field, a barometric vario helps you climb away, and a wind screen sets the wind used for the glide figures. It buzzes when a field drops into or out of range, and a safety-margin setting keeps a height buffer in every calculation.
One online activation ties the licence to your watch; after that everything runs offline. No account, no subscription.
