For those of you looking to get your feet wet with iOS or Android development for either games or apps, engine developer Unity3D is currently offering the iOS and Android SDK development modules for free until April 8th along with the core Unity Free toolkit necessary for use with the modules. The modules also allow for a full Android/iOS license of the Unity toolkit for personal or small-scale commercial use while additional features require the purchase of the Unity Pro license which starts at $1500 a seat, with a 30 day trial.
The entire package is available now and only requires registration to download. No credit card or other financial information is necessary to complete the transaction and the core SDK and modules are more than enough to get started on learning basic game development. Unity3D is one of the most popular toolchains for mobile game development and the current availability of the Android and iOS modules for free underscores the drive by the company to draw hobbyists and small development teams to the game engine.
