Some of Android’s applications (like Loco) are primarily for the purpose of social networking but also use geo-location as a supplement. Other applications are designed primarily for their geo-location services. That’s the case with GeoLife which lets you create To Do lists on your Android phone and then have the phone tell you when you’re going to be able to do them. In other words, you can enter that you need to pick up groceries; then when you’re in the area of the grocery store your Android phone will notify you that it would be a good time to do that errand. Future versions of GeoLife could also implement routing tools to let you better plan out your trips from your mobile phone (something that would help you be a greener mobile phone consumer without any effort!)

Requirements: Android compatibile mobile phone.
