Have you ever wanted to “hear the distinctive sound of a shaver” on your smartphone? If you own a BlackBerry device you can, thanks to the app Mega Shaver. The software was developed by S4BB Limited, a Hong Kong based company which is also responsible for 48,000 other apps available in BlackBerry World. You read that right. As initially spotted by BerryReview, one developer is responsible for a third of all the apps in BlackBerry World. A well-developed app ecosystem has long been a stumbling block for BlackBerry, which lags far behind Android and iOS in the number of apps available in its mobile app store. But this news makes the situation even more desperate, especially after BlackBerry CEO Thorsten Heins announced that BlackBerry World hit a milestone 120,000 apps back in May. This means that without S4BB Limited, BlackBerry World would be home to well under 100,000 apps.
