Multiple things can spark old memories. A song or an amazing dish at a restaurant are some of the most common. However, there are many times when memories seem to flee our thought, making us miss out on those events that make life great. BuildACircle was an app that brings memories back to thought.

Now, BuildACircle is relaunched and rebranded under the new name, Moments. The app brings back memories by sending a notification to your iPhone reminding you of a specific event. However, one pitfall many similar applications had was having to remember to add the significant event in the first place.

Moments solves this problem by making use of your Facebook profile (photos, posts, etc) to find these memories. In the near future, Moments will make use of other services like Instagram to offer even more memories.

Moments is available for free on the App Store today.

The whole Teens in Tech team would love to congratulate the Teens in Tech Incubator 2011 alumni, Rico Mok and Evan Huang. Please check out their video, showing Moments in action.
