TRiPi is a full-featured Professional Stage Rally Tripmeter implemented on a tablet. It has two stopwatches, three distance recorders (odometers) measuring Kilometers or Miles, or KPH/MPH, and an Official Rally Clock.
It also has a current speed display in KPH or MPH (which will also show the maximum speed reached) a display to show current heading in degrees and compass points, plus a display for the current GPS coordinates.
Using the GPS sensors, which can determine position to within a few meters, the odometers are potentially more accurate than a tripmeter connected to a gearbox. Readings show hundredths of a kilometer/mile. They can show increasing or decreasing distances, and can have a preset starting distance.
The stopwatches show tenths of seconds. They can be set to start from zero, from -1 minute (for use on a stage start line) or they can be set to start automatically as soon as vehicle movement is sensed.
The clock can be adjusted to display Official Rally Time.
The stopwatches and odometers are operated very simply, by tapping the display to start the meter, tapping to pause/restart, and swiped to reset. Each meter can be set to continue running in the background when the display is paused, or to stop with the display. The tripmeters can be reversed, or set to a specific reading.
All seven meters can have their individual intensity adjusted, and reduced to zero if desired. Background and foreground colors can also be swapped.
Every action is recorded and can be displayed in a table, by tapping the recorder button.
There is also a day/night mode button, which displays the meters as normal (day) or with dimmed colored digits on a dark background (night.)
TRiPi also features an overlay map, showing current position, route taken, pins to denote where/when a meter was tapped, plus waypoints. Trips can be stored and recalled.
