The Stopwatch is a utility app for measuring elapsed time with lap support and configurable millisecond precision display.

This is an External-apps-informations (.ppma file on the SD card).

Display

The stopwatch shows two rows in large digits:

Row Label Color
TOTAL Total elapsed time since last reset Minutes: 🔴 red, Seconds: 🟢 green, Milliseconds: 🟡 yellow
LAP Time of the last lap mark White

Time is displayed in the format: MM:SS.mmm

Buttons

Button While stopped While running
START / STOP Starts the timer Stops (pauses) the timer
RESET / LAP Resets the timer to zero Records a lap time
EXIT Exits the app Exits the app

Milliseconds Display Level

When the timer is stopped, an option field in the top right controls how many millisecond digits are shown:

Setting Digits shown
& - - 1 digit (hundreds)
& & - 2 digits (hundreds + tens)
& & & 3 digits (full milliseconds)

This option is hidden while the timer is running to prevent accidental changes.

Notes

  • The timer continues accumulating time correctly after a pause — resuming does not reset the elapsed time.
  • Lap time is fixed at the moment the LAP button is pressed; the TOTAL counter keeps running.
  • Only one lap time is displayed at a time; pressing LAP again overwrites the previous lap.
