Nowadays, I have worked on an iPhone project named Replay My Day. The App is GPS tracking tool that collects your gps location and it displays your daily route on map inside of the iPhone.
It has ability to track your location through GPS or Cellular network with minimum battery usage (I’ve got tired exactly working on this). So, you can also share your GPS diary with your friends through twitter, facebook or e-mail.
There is a great part inside of this app named “time-travel”. You can be able to replay your previous route diaries on map as well as annotations which you made in many location through app. These are can be photos, notes, twitter, facebook etc.
Finally, I’m proud to work on it with Victor van Doorn who is owner of Replay My Day App.
