After a meeting or a long day of shopping, you fish out your phone and see multiple missed calls from an unknown number. While there might still be some who may be quick in calling the number back (it may indeed be an emergency), most of us nowadays will think twice before doing so. After all, behind that number may be among swarms of undesirables that we would rather not talk to. But what if that number may be the client you pitched to, the university you sent your application to or maybe, that rather nice guy who you gave up his line in the coffee shop for you? CallerSmart is an app that helps you find information about unknown calls or texts by simply searching the number to get all the data you need to make or not make that call. CallerSmart lets you investigate a suspicious call or text by reading comments about the number from other users; avoid annoying telemarketers, bill collectors, scammers, prank callers, even ex-lovers through the search results from their database which covers 600M numbers. You can also help other people by contributing information on the phone numbers you know about while earning prizes and having fun. Your input will be appreciated and will be rewarded through Caller I.Q. points which you can use in receiving prizes and badges for helping the CallerSmart community. CallerSmart reports to having 225,000 active users and 40,000 searches per day. See how it can benefit you and how you can help outsmart unwanted callers by downloading the app free in the App Store.
