re: Is there really an app gap on WP?
I run 2 phones - an iPhone 5 that I'll upgrade later this year, and a Lumia 930. One for personal, and one for work.
What I find is mainly missing, are app for controlling consumer electronics (my TiVo, my Olympus Camera) and apps for banking. Otherwise, I'm good (although it is about time Microsoft got Facebook to build their own app instead of MS having to write one).
Back in February, there were two news stories within days of each other. Microsoft said 60000 phones were running the Win10 Tech Preview, and AdDuplex said these accounted for 0.2 % of unique devices it saw that month. So 6 months ago there were 30 Million Windows Phones in regular use (and that included a few hundred thousand WP7 devices). In January, Google announced it regularly sees 500 Million Android devices (including all the AOSP devices that don't use the Play Store, and tablets) in use. In May it was announced there are 94 Million iPhones (not iOS devices, just iPhones) in use in the USA alone.
This is why the App Gap exists. There are probably 10 times as many iPhones, and around 15 times as many Android Phones in use as there are Windows Phones. Since development for Windows Phone has been (up until recently) completely different to development on iOS or Android, it involves the same amount of cost but will only reach a fraction of the users.
Now, I am crossing my fingers that the three things Microsoft are doing are going to change those numbers so dramatically that there will be no disincentive to develop for Windows 10
- Microsofts target to have Windows 10 on 1 Billion (in use!) devices in 3 years, by basically giving the OS away. They've made a good start with 50 Million in a month, and that's even before those 30 Million or so WP peeps get their upgrade
- The Universal Windows App platform. Write one app, that targets those 1 Billion devices, and it doesn't matter if it's a Surface, a Lumia or an Xbox, it will run
- Forget Astoria, it's Project Islandwood that is the big news. Devs can take their iOS apps, and with only a partial rewrite, create a Universal Windows App that runs on all 1 Billion of those devices
Someone at Microsoft has been watching the Kevin Costner movie Field of Dreams. "Build it, and they will come...".
