ESRI is hosting a Massive Open Online Course (MOOC) on building your own Geo Apps.  They state:

You don’t have to be a software developer to build valuable geo-enabled apps that make your communities smarter and businesses more successful. This course will show you how to combine location and narrative in one application to better communicate and broadcast your story, create custom web applications that solve problems in your community, and build powerful native applications for iOS and Android devices without touching a piece of code. If you are a developer, you’ll be interested in Esri’s APIs, SDKs, and the buzzing GeoDev community.

The course includes:

• Hands-on exercises, short video lectures, quizzes, polls, and discussion
• 4 week course with 7 sections open throughout the course, 1-2 hours of study per section
• Certificate of completion and awards

You will be exposed to application templates and test drive Web AppBuilder and AppStudio.  The free online course runs from February 3 to March 3, 2016.  Check it out and sign up!
