Who Calls Me?

One of Europe’s leading phone-spam checking services, with websites in nine countries and an Android app that warns about and blocks nuisance calls.

The challenge

Unsolicited calls are a problem everywhere, and number-rating sites came and went without ever warning you as the phone rang. What began as a director’s side project was brought in-house.

The solution

Launched in 2014, the multi-domain website shares one trusted brand across the UK, US, Czech Republic, Slovakia, Germany, Switzerland, Austria, Poland and Russia, and quickly became one of Europe’s leading spam-checking sites.

A native Android app built with Xamarin hooks into the call screen to flag spam before you answer and can automatically block persistent callers.

Highlights

  • Nine localised domains under one brand
  • Real-time caller warnings and automatic blocking
  • Used by thousands of people in Czechia and Slovakia
  • Hosted on Azure with SQL Server
