TRiPi is a full-featured Professional Stage Rally Tripmeter implemented on a tablet. It has two stopwatches, two distance recorders (odometers) measuring Kilometers or Miles, and an Official Rally Clock.

Using the GPS sensors, which can determine position to within a few meters, the odometers are potentially more accurate than a tripmeter connected to the 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 bottom display is used to show the Rally Event name, useful information such as "No GPS Signal". The current position can be displayed by tapping the GPS button. This button is color-coded to indicate GPS signal strength.

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.

All six 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.

TRiPi also has a full on-screen tutorial to demonstrate every feature of the app. It runs for approximately ten minutes, but can be stopped at any time.

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.)
