The beautiful, open source framework for developing hybrid mobile apps with HTML 5

Justin James

"So you want to build a native app?"

More Platforms.  More Problems.

Why are we still coding for multiple platforms?

The Downsides of Native

  • Proficiency in each platform required

  • Entirely separate code bases

  • Timely & expensive development

  • Diminishing returns

"Is there an alternative?"

Web code 

wrapped in native layer

with direct access

to device APIs

"Hybrid apps are slow!"

"The Times They Are a-Changin"

Mobile devices have rapidly improved!

Year Device Processor RAM
2007 iPhone 620 MHz 128 MB
2010 iPhone 4 1 GHz 512 MB
2015 iPhone 6 1.4 GHz dual-core 1 GB
