While Addappt has been teasing painless contact syncing between iOS-using friends and colleagues since its December launch, its invitation-only nature has kept most of us on the sidelines. It may be time to try Addappt now that an update opens the doors to the public. On top of widening the app's audience for its update once, share everywhere approach, the 1.3 release brings group management that easily lets us lump coworkers or social circles together. Messaging is appropriately easier as well -- it's possible to quickly text or email everyone in a given group, including the option to share more photos at once than the five that iOS usually allows. A port to Android isn't yet on the cards, but iPhone and iPod touch owners tired of missing phone number changes can give Addappt a whirl today.
