Trainer Stopwatch

Trainer Stopwatch is a stopwatch built for coaches and officials - time several athletes, lanes or intervals at once, tag laps with colors and your own names, and keep the whole session in one place. No ads. MULTIPLE STOPWATCHES AT ONCE Set up as many stopwatches as you need on the main screen and switch between them with a single tap. Name each one after an athlete (Lubos, Eva, David…) or a lane. MARKS WITH YOUR OWN NAMES AND COLORS Tag each lap with a color and your own label - Sprint and Pauza, for example. Effort and rest are clear at a glance. LAP AND SPLIT TIMES Switch between lap times and cumulative split times with a single tap. HISTORY AND DETAIL Save every measurement under its own name. History is grouped by day. The detail view shows the final time and every colored lap - exactly as they were when you saved them. SHARING AND EXPORT Share results as text for free. Export to CSV and Excel (XLSX) is a one-time purchase that unlocks it for good. CONTROLS THAT FIT YOUR HAND Optional volume-key control, a sound on start/stop/lap and a notification while the stopwatch runs in the background. Light and dark theme (Material 3). WHAT'S NOT IN IT No ads. No tracking. No sign-in, no account. It runs offline and collects no data about you - everything stays on your phone. English and Czech.
