But, despite the milestone, the app has a poor two-star rating, based on more than 11,000 reviews, with the majority of reviewers giving it just one star. What gives?

HTC is prepping a budget version of its feted HTC One handset, according to a new report. The rumours suggest that HTC is gearing up to launch the pared down smartphone in June and is currently developing it under the HTC M4 codename. According to "sources from the upstream supply chain," the M4 will feature a metal alloy chassis supplied by Catcher Technology, with HTC predicting initial Q2 demand of 700,000 units for the new handset. The manufacturer is said to be hoping that establishing exclusive relationships with its suppliers will help it avoid the kind of component shortages that delayed rollout of the HTC One in some regions. In addition to a sleek metal look, the HTC M4 is tipped to feature a 4.3in HD (720p) display, 1.2GHz Snapdragon 400 chipset, and an 'UltraPixel'-branded camera. Elsewhere, the M4 is expected to offer 16GB of on-board storage, plus the most recent iteration of Android, 4.2.2 Jelly Bean, as augmented by HTC's custom UI, Sense 5.0.

When an event as large and established on the IT calendar as Infosec comes around, it’s always likely to take up some healthy column inches in the tech press, but the state of Internet security at the moment throws more significance than usual on this week’s three-day showpiece in London – when ITProPortal will be attendance. With so much activity unfolding in the security world this year and its wider implications becoming more significant than ever, the light shines brightly on the engineers, researchers, experts and company executives assembling at Infosec this week. These are the ones providing countries with the insight and technology to shore up the cyber sphere, and, more directly for most at Earls Court, the ones who promise to protect their business. The digital sparring between powerful countries and their most adept hackers is eroding the layers of protection around these businesses, putting huge emphasis on the support network brought together at Infosec. The stage is set for the event, so get the full low down on why Infosec 2013 may be more significant than any of its predecessors.

Windows Phone hits a new low with the Nokia Lumia 520. By which I mean a new low price. So keen are both Nokia and Microsoft to establish Windows Phone as the smartphone operating system everyone wants – and everyone can afford - that they are moving further and further down the price range in order to cover as many budget bases as they can. What we have here is a Windows Phone handset that’ll set you back just £150 SIM-free. That price puts the Lumia 520 on par with budget-end Android handsets and is a far cry from where the OS started – at the top of the money tree. But is this a worthy low-end option or a handset to avoid. Follow the link to find out in our full review of the Nokia Lumia 520.
