There is more to this than just numbers
I'm referring to Quality.
Some of the Android apps I've installed are so flaky that as a Software Dev I'd be ashamed to release things with so many bugs.
If you contrast that to the app I used on my old iPhone, frankly there is no competition. the iPhone wins hands down.
It appear that the Android App devs have been afflicted by the Microsoft/FOSS Disease (and I'm speaking as a FOSS dev in my spare time) that they don't understand the meaning of 'Getting to Done'. i.e. making the app complete and work properly before releasing 'stuff' before it is ready and letting the users find the bugs.
MS has been doing this for years. It is a habit that many OpenSource projects have adopted as well. I applaud the efforts of the LibreOffice Community to clean up and fix the bugs in the codebase they inherited.
I wish more projects would adopt a 'This release is going to be a bugfix only'.
