iPhone Screenshots


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.

Ratings and Reviews

It's crap

Bill Canfield

You think this app is going to work. You open it and activate it and put your phone in your pocket and set out for an epic bike ride… you get home, excited to see how far and how fast you went, and you realize that when your phone's screen locks, the app stops. If I were to review this app in one word, that one word would be "garbage."

Great app, works well.


I got this app to supplement video in my vehicle to use against traffic tickets. I noticed that I can export in .gpx which is incredibly awesome. Importing the .gpx to Google Earth is a breeze. The exported file shows a data point every second instead of ten seconds on the review screen. A toggle to disable the device being able to go to sleep is basically a must for these type of programs. If one is there, I haven't found it. If it's added in, five stars.

One last thing: the correct abbreviation of kilometres per hour is km/h, not kph. :-)

Good App


I recently saw this on gizmodo so I decided to download it on my iPhone 3gs. My first thought was to look at the cool graphs that are shown on the website but I couldn't seem to find it, I think it is ipad only but that's ok.
So overall this app is very usefull for tracking you on a bike ride or long Jog plus it's free!! I also wish u could see a satlite view on ur log
