The kTool difference
No wind gear. No setup.kTool infers the wind for you.
Most tools need a masthead unit or a manual wind entry before they tell you anything. kTool works the wind out from the shape of your track — so every tack and gybe gets a real angle the moment you upload.
It's all in there
Three ways to find the gap.
Web-based
No app to install.Nothing misremembered.
No download, no app store, no updates to chase — kTool opens in any browser. Pull up a session on your laptop after racing or your phone at the club. Every tack, every gybe, every leg is kept, ready to revisit as many times as you need.
Bring your own data
Any data. Any class.No ceiling.
Whatever you record
Upload a GPS track and you're in — add instruments, wind files or video if you've got them. No proprietary box required.
GPS & GPX tracks
Onboard instruments
Wind & sensor files
Session video
Whatever you sail
If it leaves a GPS track, kTool reads it. No class list to check against — dinghies to foilers, one boat or a fleet.

How it works
From upload to insight in minutes.
01
Upload
Drop in your session — GPS, wind files, sensor data. Add video if you've got it: onboard, drone, any angle.
02
It's ready
kTool finds every maneuver and straight line, calculates the metrics, and syncs your footage.
03
Find it
Scrub the timeline to any moment, read the numbers, cut out the leg you care about.
04
Fix it
Apply what you found next time out. Add more sessions and compare — the more you sail, the clearer the progress.
