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.

Useless for testing NI mobile data

Thought this was a great idea for letting ofcom see how pathetic the NI mobile data is for Vodafone.
Sadly, their tests rarely complete (15 mile radius - including town - is E or awful 3G with 0 upload speed - it’s so awful, rendering it pointless.

Accurate, quick, useful. Possibly the Best available; certainly my preferred option.

I’ve not been using it long but after recently upgrading my TalkTalk package I wanted to monitor developments. This app seems to be giving accurate and expected results so far as I can tell by comparison with pretty much all the other apps out there.
It doesn’t have all the visual bells and whistles of more commercial competitors but I like the professional cleanliness of it. Importantly neither does it have any pop-ups or ad’s that I’ve noticed. The ‘detailed test results’ are useful and pitched just at the right technical level I need to make performance judgements. If there was a pro version, I’d buy it.

I’m using an iPad Pro via TalkTalk (no probs) with nominal 70mbs connection. My favourite of all the many I’ve tried.

Completely and utterly rubbish - Do not use

Where did Ofcom get their data from? Let me guess, the likes of Vodafone,EE,O2,Three etc! They have been lying to their customers for years, ‘the signal in your area works fine’. I don’t even have enough signal outside for O2 for a call, yet alone any other network. Ofcom state that it has a complete across the board green stars! Look at the map and if they are not sure they use a ‘chance’ of a signal in their positive results. Shame on you Ofcom! You are meant to be regulating the mobile phone operators to ensure a decent service! Bring down the fees for the customers like us who do NOT get a good signal for ANY of the networks! Why should we pay the same as people who get good signal. You have known this for years and are full of empty promises! Try and make a call in your car and it just cuts out! Shocking!!!!! Do something about it Ofcom NOW.!!
