See where the tenths are won.

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.

The ghost

Two racers. One run. Same gates.

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.

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

Drag to compare.

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.

How it works

Ready in three taps.

Just your phone and two runs.

Choose the runs

Pick two or more videos from your gallery. One is the base run, the others are laid over it.

Sync at gate 1

The wizard asks when each racer passes the first gate. Add more gates for split times.

Compare

Watch as a ghost, side by side or split, check the splits, export and share with the team.
