I need some software for my mobile and I know I can't ask it on SU because it's not related with PCs in some way.
So for mobiles, where can I ask questions? Does the Stack Exchange Network have any community for mobiles?
If you are looking for a site that can recommend which application you should use, Software Recommendations is exactly what you want.
Since Gadgets was shut down, there's no Stack Exchange site for mobile gadgets.
The only 'exception' is Apple.SE which obviously allows questions about all Apple products, which include iPhones, iPods and iPads.
