Built for the sport

Most foil trackers are made for long runs.

Pumpfoiling is the opposite. A good run lasts twelve seconds, most attempts end in the water, and the number that really matters is how many of your tries actually got you up. Pumpline is built around that number.

What it does

Put your watch on. Push off. That’s it.

Hands-free run detection

Every push off the dock becomes an attempt, marked as landed or missed. Neither swimming back nor walking the board along the dock counts, and a quick touch-down you pump out of stays one ride.

Feel when you’re up

Your wrist buzzes the moment you reach foiling speed and again when the run ends, with a different tap for a landing and a miss. The screen turns green while you ride.

See yourself improve

Success rate week by week, time on foil, your longest ride, and a calendar of how often you get out. Open any run to see its track and its speed curve.

Know which foil works

Log your board and foil setups and the water conditions. Pumpline shows the success rate you actually get on each one, so choosing your gear stops being a guess.

How it counts

An honest success rate.

Most trackers only record the rides that work, so your misses quietly disappear. Pumpline records every try first, then decides.

You push off

As soon as you start moving faster than swimming pace, Pumpline opens an attempt.

You hold it

If you stay above about 10 km/h for 3 seconds and 15 metres, you were up on foil.

It’s counted

The attempt is saved as landed or missed. Both count, so the percentage is real.

Every foil is different, so these thresholds can be adjusted in the app. Movement too slow to have been a push off is never recorded, so walking the board along the dock creates no misses. Went straight into the water without moving? Tap “Log a miss” on your watch.
