It's true that Windows Phone (and now Windows 10 Mobile) doesn't have as many apps as Android or iOS. However, the perception of that app deficit may be just as problematic -- why would you switch to a Lumia 950 if you assumed that none of your favorite apps had Windows equivalents? Microsoft clearly isn't happy with this state of affairs, as it just released AppComparison for Android to help set the record straight. The app (a spiritual sequel to the old Switch to Windows Phone) tries to match the Android apps on your phone with their mobile Windows counterparts, either giving you an exact parallel or the next best thing.
