Android Pros

Android development can occur on various platforms. It provides open access to app functionality, enabling call history access, inter-app notifications, and content sharing. Apps can be installed from several sources, and publication to Google Play is low-cost (one-time $25 fee).

Android Cons

Android faces significant fragmentation across OS versions, impacting app compatibility. Upgrades are delayed by manufacturer/carrier customizations, demanding complex user experience adaptation. Graphics performance can be slower on some Android devices.

iOS

iOS is a mobile operating system based on Unix, developed for iPhones, iPads, and other Apple devices. It has multiple layers, including Core OS, Core Services, Media, and Cocoa Touch. It's known for its multi-touch gestures.

iOS Pros

iOS upgrades are generally well-adopted; a high percentage of users are on the latest version. New features roll out quickly. The OpenGL API is consistent across iOS devices; navigation isn’t prescribed, allowing app-specific designs.
