Bestmarked is a precision stopwatch for all athletes. Time your Track, Running, or Agility events and it automatically detects personal records and builds a progress graph — no manual entry, no spreadsheets. No account required, no ads, no subscription. Covers Sprint distances, Running (400m–5K), and Agility drills (shuttle, 3-cone, 40-yard dash). Built after watching a family member maintain a training spreadsheet by hand for a full season — the graph, not the clock, was always the point.
