Mobile app to meet one another

Edit: No, it's not Tinder.

Two people who know each other want to meet up. They both have a smartphone with a GPS device.

There could be an app to spare them planning a meeting point, and that would instead calculate for each of them the shortest path from one person to the other and update it every now and then.

Differences between iOS and Android development

Android is programmed in C, C++ or Java, whereas iOS is programmed in C, C++ or Objective-C.

In a commercial point of view, Android seems to have a bigger market share.

People argue that iOS have better apps: all iOS devices have identical specs and features, disregarding resolution. It is easier for a developer to take advanatage of the whole screen, trust it will run smoothly... Android devices are different.

Developing Android apps for Android on Eclipse requires tons of module installations, AVD configuration. The default Xcode installation requires absolutely no complementary configuration. The app can be launched directly once the project is created.
