Hello Everyone, I am new to unity 3d and I wonder would it be the best tool to implement GPS based application. Thanks in advance.
It depends on what sort of GPS based application you're making. If you want something with platform-standard UI, like MapMyRun or similar, then no. If you want an app with a completely custom UI, perhaps some sort of game that you interact with using your real-world position, then sure, Unity would be great for that.
