IM, text, and video-chat capabilities have shoved the old phone call aside. Thrutu looks to update voice-to-voice communication by letting users share contacts, photos, and more as they gab. The best utility is a location-sharing function that shows you and your buddy on a map.
WIRED Shows you which contacts have the app installed. Does in-call coin flips and shared browsing.
TIRED Works only if carrier supports simultaneous data and voice. Must initiate calls in-app on the iPhone.
