We categorise calls by type (debt collection, serious number, sweepstakes, etc.) and give the number in question a tellows score, which indicates whether a number is trustworthy or suspicious, helping you to decide whether or not to take the call.

    We've all had to deal with the same thing. Does this situation ring a bell? Unknown callers pester you all day long and you wonder if answering the call would be waste of your valueable time? Hence the question, who calls me? Unsolicited calls are a menace around the world, they operate in the twilight of the barely legal - if at all. tellows intents to provide a system to categorize the caller according to its nature and, thereby, warning you about possible dangers to you nerves and purse.
