AppGyver Steroids.js Closes the Performance Gap Between HTML5 and Native Apps

New AppGyver Steroids.js Draws on Native UI Components, Navigation and Animations to Achieve Native App Performance

SAN FRANCISCO, CA--(Marketwired - Aug 21, 2013) - AppGyver (, provider of innovative tools for rapid mobile app development, today announced the release of its new AppGyver Steroids.js, designed to close the gap in performance between native mobile apps and PhoneGap based HTML5 hybrids. Please see:

Adobe's PhoneGap is a popular open-source HTML5 hybrid app framework. Hybrid apps have several advantages, including cross-platform re-usable code, a rich trove of open source libraries and technologies, and a ready pool of web development talent. However, in terms of performance, HTML5 hybrid apps are generally not on a par with fully native apps. Since app performance is crucial to meet today's high standards, it can be a difficult decision whether to develop native or hybrid apps.

AppGyver Steroids.js resolves this app development dilemma by utilizing native UI components, navigation and animations, together with the HTML5 wrapped application. This enables AppGyver-based apps to achieve native app performance in hybrid apps and offer the best of both worlds: HTML5 hybrid apps with animation and other performance results that are indistinguishable from those of native apps.

Apps can be developed with AppGyver Steroids Toolbelt, a development tool used by thousands of companies including Fortune 500 companies such as IBM, Accenture and Intuit. PhoneGap developers can transfer their projects in seconds, and then use AppGyver Steroids.js to boost app performance or extend their existing projects.

"We are extremely excited with our beta debut of AppGyver Steroids.js, and we look forward to a flood of HTML5 hybrid mobile apps with performance levels that match their native counterparts," said Marko Lehtimaki, AppGyver Founder and CEO. "This is another milestone in achieving our mission to make the building of HTML5 apps that are indistinguishable from native apps rapid, pain-free, and fun."
