Speed Vario

Speed, altitude, climb rate: the three numbers that matter when you are moving, live, on your wrist or in your pocket. Speed Vario is the instrument for cyclists, hikers, skiers, paragliders, sailors and pilots who want an accurate reading — no account, no subscription, no ads.

SAY WHAT YOU ARE DOING, THE SCREEN FOLLOWS
Walking, cycling, driving, skiing, paragliding, flying or on the water: every activity gets its own dashboard. On foot, pace and cadence. On skis, runs and lifts counted, with their names. In the air, QNH, flight level, airtime and the airfields you used. On the water, knots, heading, depth. Speed is measured, altitude fuses barometer and GPS, the variometer reads every climb and every sink.

ON YOUR WRIST TOO
On Apple Watch, everything live — and standalone recording when the iPhone stays home. Paragliding, the vario taps your wrist to the rhythm of the lift. And for heart rate, a Bluetooth strap is enough — Polar, Garmin, Wahoo and their equivalents — with or without a watch.

FIND YOUR WAY
Follow a route on the iPhone and the Apple Watch, with a voice when you stray: import a GPX, or draw your own on the map, snapped to the trails. Mark a point and aim at it - bearing, distance and, in flight, the glide ratio needed to reach it. In the air, your height above the ground below, and a recording that starts by itself at take-off.

THEN, RELIVE THE OUTING
A logbook per activity, with the totals. Your track laid over real 3D terrain, a chase camera that replays it second by second, a fly-through video to share. Compare two outings, recognise a route you have done before, export to GPX, FIT, IGC, KMZ or CSV.

SHARE IT LIVE, PRIVATELY
Send a link or a QR code and someone you choose follows your outing on a 3D map, in real time, from any browser - no app, no account for them. It is optional and off by default. Everything is encrypted on your device before it leaves, and only the link opens it: the developer cannot read your position or your heart rate. A red Stop button is always within reach, and the link ends with your outing.

SAFE, AND YOURS
An optional iCloud backup copies every outing to your own iCloud space and brings it back on a new iPhone - your heart rate is never stored in iCloud. Everything works offline, down to the map and its place names. No account, no ads, no trackers. Live sharing, if you turn it on, is end-to-end encrypted: your data stays yours.
