Upwind - Sailing Tracker

Live speed and course on your wrist, speed-colored tracks of every sail. No accounts, no ads — your data stays yours.

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

INSTRUMENTS

• SOG (speed over ground) in knots, smoothed for reading at a glance
• COG (course over ground) on a compass ribbon
• Automatic night mode: red instruments after sunset to preserve night vision

RECORDING

• Explicit Rec button: recording never starts on its own
• Speed-colored track, from cyan (slow) to coral (fast), scaled to your session
• Distance, average and maximum speed, duration
• On Apple Watch, recordings also save as Sailing workouts in Health (with your permission)

WATCH, IPHONE OR BOTH

• Apple Watch records standalone with its own GPS
• iPhone and iPad are full trackers too, with live map and instruments
• Sessions sync automatically between your devices through iCloud

AFTER THE SAIL

• Scrub through the speed chart: speed, time and position at any moment
• Standard or satellite map, free of clutter
• Share sessions via AirDrop, export GPX, import GPX from other apps
• Nautical coordinates (degrees and decimal minutes)

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.
