We want to build a smartphone app which uses geolocation, etc. and target the most important smartphones. Which OS would you support for a b2c application? I found a german statistic here: http://de.statista.com/statistik/daten/studie/150842/umfrage/prognostizierte-marktanteile-der-smartphone-betriebssysteme-in-2013/ which forecasts the smartphone usage for 2013. To summarize it lists the following OS, ordered by priority:
Symbian, Android, Blackberry (RIM), Windows Mobile, iPhone
Would you agree with this priority or should we start with the classical: iPhone/Android combo?
It probably depends on the market you're targeting. The statistics you're quoting might be right for Germany but in the US situation is quite different. Blackberry still holds the biggest share, but if your app is a consumer (not business) one, iPhone/iPad and Android is the clear choice. Symbian is not a large player here at all, besides, there's a lot of talks going on about a crisis of the platform so I wouldn't even take it into consideration.
