Rally Computer

簡單的反彈計算機為offroaders有用

Rally Computer is a GPS odometer app useful in off-roading with roadbook.

Rally Computer measures 2 distances :

•distance since last reset (TRIP)

•total covered distance (ODO)

Features:

TRIP and ODO - Only most essential measurements

Big button - Easier to use during off-roading

Pause/Resume/Stop - Measurements can be pasused and resumed when needed

Kalman filter - Advanced filter used to smooth out the track. Improves accuracy

Export to Androzic - Export tracks to the navigation app Androzic (GPX file)

Quick distance adjustment - Allows to quickly adjust distance by a fling gesture.

Menu options:

•PAUSE - the measurement is paused (GPS is on)

•STOP & CLEAR - the measurement is stopped, all distances are cleared (GPS is switched off)

•EXPORT GPX TRACK - current track since last START is exported to a GPX file (see the tip below)

•SETTINGS - additional settings such as selecting destination folder for exported tracks, Kalman filter to improve measurement accuracy, Units (miles, kilometres).

•ABOUT

•EXIT

Settings:

•Folder for exported GPX files - You can browse the file system and select a folder where exported GPX files will be stored.

•Kalman filter settings - Kalman filter is an algorithm used to smooth out the track. This improves distance measurement since GPS accuracy is often far from ideal.

TIP:

If you would like to load the track in Androzic then

1. Select menu option Settings

2. Select the folder where Androzic stores GPX file, should be something like [SDCard or internal memory]/Androzic/data.

3. Once you export GPX track it will be stored in this folder so that it will be available in Androzic

4. In Androzic select menu option Tracks -> Manage -> Load track from file

5. Pick the track file (rallycomputer_track_[date]__[time].gpx)
