Are you a Ruby developer interested in mobile development, but needing a bit of help to get started? Look no more!

We offer full 5-day classes that will teach you everything you need to know about iOS and RubyMotion, from the very basic concepts to advanced topics. Experience with iOS is absolutely not required.

At the end of the training you should be able to start writing full-fledged apps for iPhone or iPad in Ruby.


This is a hands-on training. You will get to write a few iOS applications during the course. You will also be given exhaustive material and access to a dedicated forum where you can discuss with the instructors and other students.

Currently, the course focuses on iOS. An Android version is under preparation.

The training costs $2500 per student. Because we want to deliver high-quality training, our classes are small (25 students at most) and we always provide two instructors. We offer a discount for groups.

Requirements: The entire course is given in English. You should have basic Ruby knowledge, a Mac computer, a provisioned iOS device and a valid RubyMotion license. That's all!

What our alumni are saying

"Cyrus Innovation sees lots of opportunities to develop iOS apps for our consulting clients. We were excited to take the training, since we have a strong corps of Ruby developers. Laurent and Norberto delivered a great, wide-ranging introduction to both RubyMotion and native iOS development. We came out of it with the knowledge and confidence to take on developing native iOS apps. In the weeks since, we've already taken on our first paid RubyMotion work and we're moving fast thanks to the great kick-start." Paul Infield-Harm Directory of Product Development, Cyrus Innovation
"The folks at HipByte are amazing instructors. Their easy manner and depth of knowledge helped them adjust to the specific needs of the people in the room. The exercises were rich and enlightening, and the course was very interesting and informative. Overall, five days of training was definitely a worthwhile investment!"
