Stopwatch

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.
