NiteEvo is an iPhone app that allows you and your friends to capture, share, and relive your nights.

You start your night by choosing a group of friends. Your group is completely dynamic, and you can add friends as your night unfolds.

NiteEvo's feed creates a timeline of your night's memories. The feed pulls your and your friends' comments and photos to create a real-time conversation telling the story of your night.

NiteEvo's map lets you see where you and your group of friends are during the night. It also allows you to scroll back through time to see where everyone has been, throughout the night.

With NiteEvo, you can choose to record your location, even when the app is inactive. This means you can start a Nite, close NiteEvo, and do your thing. The next day, when you look back through your Nite, you can see your whole journey on the map.

At the end of your night, NiteEvo archives your story so you can share and relive your most memorable moments with your friends.
