In or out. Shown.

LineCheck will call the lines from phones placed behind the baselines, with a replay of the landing ready before the next point starts.

The rule

The line is in.

Every court line is 40 mm wide, and a line belongs to the area it bounds. A shuttle that lands on the line, even on its outer edge, is in.

At full speed, a few millimetres decide the point. LineCheck is built to show those millimetres, and to say so when the video cannot.

OUT IN (COURT) 40 mm IN
Touching the outer edge of the line counts. The shuttle above is in.
What it will do

Line calls you can replay.

Built after ServeCheck, on what club players teach us about calls on court.

A replay of the landing
See where the shuttle came down, frame by frame, before the next point.
Phones, not towers
Phones on stands behind the baselines. Nothing fixed to the court.
Challenges
Play challenges the way your club or league plays them.
Says when it can't tell
If the landing is hidden or unclear, LineCheck makes no call and tells you why.

Hear when LineCheck is ready.
