According to MicrosoftInsider.es one of the apps is HP Voice Recorder, which will apparently do what its title suggests: record audio from an HP product with the twist that it will be in stereo. The other app is HP Device Hub, which will offer info on accessories and apps for owners of an HP product, along with special offers. The site claims HP has even more apps under development, with one of them code named "HP Alfred".
The HP Elite X3 is likely to be a big part of the company's Windows 10 app plans. The 5.96-inch Windows 10 Mobile device does not yet have a launch date or price.
