Upwind - Sailing Tracker

Upwind is a sailing tracker for Apple Watch, iPhone and iPad: live speed, course and manoeuvres, and every outing recorded with a speed-colored track. Free, with no accounts and no ads.

INSTRUMENTS
- SOG (speed over ground) in knots, big and readable at a glance
- COG (course over ground) written on a compass ribbon
- Six live values: COG, distance, average, MAX 10s, manoeuvres and peak
- MAX 10s: the best 10-second average, so a wave or a GPS glitch can't inflate it
- Tacks and gybes counted while you sail
- Speed chart of the whole outing, with time and speed axes
- Instruments or Map view on iPhone, portrait and landscape; iPad shows everything on one screen
- iPhone Duo support
- Automatic night mode: red instruments after sunset to preserve night vision

LOCK SCREEN AND DYNAMIC ISLAND
While recording on iPhone, speed and course stay on the Lock Screen and in the Dynamic Island, with time, distance and the last 10 minutes of speed. Keep the phone locked: the track keeps recording.

RECORDING
- Explicit Rec button: recording never starts on its own
- Speed-colored track, from cyan (slow) to coral (fast), scaled to your session
- Recording keeps going in light air and at anchor with the screen off
- Sessions saved to Health as Sailing workouts with their route (with your permission)

WATCH, IPHONE OR BOTH
- Apple Watch records standalone with its own GPS: big speed, compass with your course, live manoeuvres
- iPhone and iPad are full trackers too, with live map and instruments
- Sessions sync automatically between your devices through iCloud

AFTER THE SAIL
- Each session shows distance, duration, average, MAX 10s, manoeuvres and peak
- Tacks and gybes marked on the map: tap one and the chart jumps to that moment
- Scrub through the speed chart: speed, time and position at any moment
- Standard or satellite map
- Share sessions via AirDrop, export GPX, import GPX from other apps
- Nautical coordinates (degrees and decimal minutes)
- A Glossary explains every abbreviation and how values are worked out

PRIVATE BY DESIGN
No accounts, no developer servers, no ads, no analytics. Your data stays on your devices and in your private iCloud.

TIPS
- For sessions longer than a couple of hours, record with an iPhone or iPad connected to onboard power
- On iPad, GPS requires a Wi-Fi + Cellular model

Continued use of GPS running in the background can dramatically decrease battery life.
