Why we chose to make an app over Arduino

We have decided to work on the Fruit Tree Mapping Project. I decided NOT to do anything regarding Arduino as I already know the platform. Both of us have no prior experience making apps so we think we can get a lot out of this project.

For now we have to choose which platform to program for. Due to limited manpower and time we can only choose one platform. The following info is taken from here

Android apps are programmed using C, C++ and Java. It is an "open" platform; anyone can download the Android source code and Android SDK for free. Anyone can create and distribute Android apps for free; users are free to download apps from outside the official Google Play store. There is, however, a one-time $25 registration fee for developers who want to publish their apps (whether free or paid apps) on the official Google Play store. Apps published on Google Play undergo a review by Google. The Android SDK is available for all platforms - Mac, PC and Linux.

iOS apps are programmed using Objective-C. Developers must pay $99 every year for access to the iOS SDK and the right to publish in Apple's app store. The iOS SDK is only available for the Mac platform.

Thus we chose Android. We excluded Windows phones due to the small user base.
