Short track at its core
Inspired by the reality of the ice, useful far beyond it.
Short track training asks for repeat efforts, precise timing, changing intensity, loud environments and fast decisions. A useful timing app has to be readable at a glance, quick under pressure and forgiving when a session changes in the moment.
Inside Edge Timing starts there: big countdowns, clear phases, audible cues, live progress, quick stopwatch controls and a race workflow that respects the pace of a competition day.
The same tools work naturally for strength circuits, HIIT, cycling, running, rehabilitation, mobility, team-sport conditioning and custom training sessions.
