GaddoSYNC lines up two ski or snowboard runs so the gates match and the racers are the same size. Watch them as a ghost, side by side or split, and check the split times – right on your phone.
Made for ski and snowboard racers, coaches and parents.


The ghost
GaddoSYNC cuts the other racer out and lays them over your run – lined up on the course and scaled to the same size, even while the camera pans and zooms.
Kian · base run
Xavi · ghost
Same gates, same size
At 60 km/h, six hundredths is a full metre on the course. GaddoSYNC shows you exactly which turn it was lost in.
Split view
Both runs aligned to the same camera view, at the same moment from gate 1. Drag the divider – just like the Split view in the app – and spot the difference in line and body position.
Kian · baseXavi
Real frames from GaddoSYNC – Xavi’s run warped onto Kian’s camera view.
Features
No laptop, no editing software. Film from roughly the same spot and GaddoSYNC does the rest.
The other racer as a see-through ghost on your run. Choose a clean cut-out or a full blend.
Both runs in the same camera view – stacked, or split with a divider you drag across.
Add split gates and see who is faster, and by how much – green ahead, red behind.
Step frame by frame, slow motion, hold to pause, full screen.
A video with names, clock and splits. Share on WhatsApp, or by QR code to the whole team.
Your videos never leave your phone. No account, no ads, no tracking.
In the app
Big buttons and a dark screen that is easy to read in the snow.



How it works
Just your phone and two runs.
Pick two or more videos from your gallery. One is the base run, the others are laid over it.
The wizard asks when each racer passes the first gate. Add more gates for split times.
Watch as a ghost, side by side or split, check the splits, export and share with the team.
Works for every discipline
Filming tips
GaddoSYNC lines up the runs on the course itself. Help it with a steady, consistent shot.
Everything runs on your phone. Nothing is uploaded – we don’t even have a server for it.
