B4i allows you to easily develop native iOS (iPad and iPhone) apps. B4i follows the same concepts as B4A, allowing you to reuse most of the code and build apps for both Android and iOS. This is the only development tool that allows you to develop native iOS apps without a local Mac computer.

Hosted Mac Builder
The builder service allows you to develop iOS applications without a local Mac computer. All of the development steps can be done with the builder service including the final step which is uploading the application to Apple App Store. Note that the builder is currently limited to projects of up to 50mb.
If you are less experienced with Mac OS then it is recommended to start with the hosted builder even if you have access to a local Mac computer.
