Sailing Tools: COG, SOG, Heel
Sail tacktick on your phone
$1.99
Mount your phone and watch SOG, COG, heel and race timer like a mast display. Build custom screen layouts and track your sessions. Doesn't require internet connection.
This app turns your iPhone or iPad into a clear, mast-mountable racing display — large numbers, no clutter, readable in bright sun.
Built for club and keelboat racers who want real speed and heading without a full instrument install.
WHAT YOU SEE
• Speed over ground (SOG) in knots
• Course over ground (COG)
• Heel angle
• Session average speed
• Race countdown timer — 3 / 5 / 10 minute starts, sync to the nearest minute, count-up after the gun.
LAYOUTS THAT FIT HOW YOU RACE
• Resize and arrange instrument tiles
• Save named presets (Prestart, Upwind, Downwind, or your own)
• Switch layouts with one tap
• Day mode for sun; dim red night mode for after dark
• Choose digit fonts and high-contrast colours per instrument
AFTER THE SAIL
• Start and end sessions to record your track
• Review past sails on a map with speed along the track
• Add race-day notes (wind and free text — notes only, not live wind instruments)
• Save a simple boat profile (name, size, PHRF, ORC)
• Share a track via the iOS share sheet
WORKS WHERE YOU SAIL
• Fully offline while racing — no cell or Wi‑Fi required for instruments
• Uses the device GPS and motion sensors
