Upload without cleanup
Bring files straight from your watch, tracker, or export tool and start reviewing without spreadsheet work.
Feature
Upload a GPX, FIT, KML, or TCX file and turn a raw track into a structured review of VMG, tack quality, point of sail, replay context, and coaching takeaways. TillerWise is designed for sailors who want to understand why a session felt fast or slow, not just where the boat went.
Bring files straight from your watch, tracker, or export tool and start reviewing without spreadsheet work.
Focus on VMG, manoeuvres, pace consistency, and tactical shape instead of generic endurance dashboards.
Use each review to identify the moments that matter and decide what to repeat in the next session.
A sailing GPS file contains position, time, speed, and heading, but the useful insight comes from connecting those signals to the way the boat was sailed. TillerWise turns the upload into a review flow that helps you find the moments that changed the session.
01
Start with the sailing area, leg shape, and manoeuvre locations so the numbers have context.
02
Use VMG, speed, heading, point of sail, and manoeuvre quality to find repeated gains and losses.
03
Relate the result to weather and previous sessions before deciding what to change next.
Use map replay to revisit each leg, then move into the metrics view to see where pace was won or lost. TillerWise keeps the qualitative and quantitative parts of a sailing debrief in the same place.
If you also sync from Strava, you can reduce manual imports and keep your best sessions flowing straight into analysis. See how Strava sailing import works.
The strongest sessions for analysis usually have a clear training purpose: repeated tacks, upwind and downwind legs, speed testing, or a known course shape. These patterns make it easier to compare like with like and separate technique changes from conditions.
For mixed sessions, the map and timeline still help. Use them to isolate the most useful parts of the track, then save the review as a reference for the next time you sail similar breeze or drills.
