CALLAROUND

Smartphone-based communication service, combining a) voice calls, b) geolocation and c) twitter-like hashtag grouping. CallAround gives ability to find people geo-closest to you by hashtag (profession or interest or whatever) and voice-call them with your phone. User can become "findable" too. Example: 1. User enters tag - for example #taxi 2. He taps it to find other people around you with tag #taxi or just call closest 3. Success: he can order a nearby taxi. 4. Then... he taps another button on tag #taxi, stating that other people now can find and call him as in step 2 (he can toggle this state, if he don't want to be found at the moment) 7. Success: he is now himself a "taxi driver" - when he wants to. Service proposes a multitude of social and small business uses - with tags like #girlWantsCinema, #occupySchoolLibrary, #beerNow, #emergencyLawyer, #washMyCarNow etc. Has Twitter and Facebook integration (profiles, groups, likes).More
