Download from AppStore

Record location, heading, speed, altitude, accelerometer, sound level, trip duration and distance to storage on the device. Each log can be viewed on a map and individual samples inspected. Export logs via e-mail in CSV, JSON, GPX or Golden Cheetah format. The entire local sqlite database can be exported as well.

Log files can be uploaded to Google’s Fusion Tables, where they can be further visualized.

Double-tap the Dashboard screen to dim and "lock" the display. The proximity sensor is used to turn off the display while logging. Sleep/lock timer is disabled while logging, however non-dismissed notifications may interfere and allow the device to sleep.

Note: This application requires GPS functionality to operate correctly.

By default, logs contain a unique identifier for each device. This may be omitted by enabling the "Anonymous Export" option.
