Love it, works perfectly.

I had been considering buying a $100 device and/or eyefi SD card for about the same, when I came across this app.

I plan on using this app to track my movement around Europe and will later sync the geotags with all my photos taken with a non-GPS enabled DSLR. I have tested it locally (removed my SIM card to replicate no service), and it was a breeze.

Also, huge respect and kudos to the developer of the app. He is very friendly and quick to respond with emails (and even tweets). Previous updates had a bug with losing the track due to an iOS limitation, but I can confirm it has been resolved and fixed!

HIGHLY RECOMMENDED!
