Ofcom, the UK communications regulator, has launched an app which shows the broadband and mobile coverage availability for your address. It will also show the predicted speeds available for broadband.

The app can also test your connections and suggest tips for improving your speed. The checker quickly runs a series of tests and measurements from your smartphone or tablet to tell you how well your mobile or broadband connection is performing.

Poor Wi-Fi can have a big impact on performance and might mean you’re not getting the best out of your home broadband connection. The app will identify if there is a major drop in performance between your broadband connection and your home Wi-Fi network. It will give tips to help you fix any problems.

To get a complete view, we recommend running tests in different places, at different times, and on different devices.

Feedback can be provided to us via the feedback option in the app’s setting menu.

Great App for testing internet

I’ve been using this app to test my Sky Fibre Optic broadband which is never running Fibre speeds, however it could do with a feature that allows you to report your Wi-Fi when it is performing nowhere near like what it should be because I am quite frequently getting internet speeds of 1 Mbps when it should be in the 30s

Best checker in store

Great app if you are wanting to check your internet speed. Also deals with mobile coverage maps which helps for choosing network providers. No adds or “upgrade to this” gimmicks

Does not work - misleading

Worse than not having the app at all because it led me to think there were no other mobile signals other than the one I am on until I discovered from other people otherwise!
Does not pickup EE mobile network where signal is known to be full strength.
Does not show all broadband operators either eg. the fibre-to-the-door network available at my home for 3 years now did not feature.
