Momento has several things going for it. Not only does it collate activity from a wide array of social media apps, it is also very attractively designed and a pleasure to use. This iOS app is ostensibly a journal in that it offers a password-protected place to add thoughts but it also pulls in feeds from platforms including Instagram, Twitter, Facebook and YouTube so you're getting a review of your day too. And with Moves and Foursquare's Swarm added, you now have a picture of how many calories your burned, how long you were active for and where you visited. The whole 'Quantified Self' movement can have a practical application in this context: your personal data is combined to work like a diary. momentoapp.com
