Scringo, an emerging mobile startup that aims to improve developer productivity, just launched its software into general availability. The company offers a platform-agnostic SDK that covers the “3 Rs” of mobile application development: reach, retention and revenue.

Scringo’s feature repository includes components such as an activity feed engine, integration with Facebook and Twitter, and custom algorithms that allow developers to target their content based on metrics such as gender, age and location. The package also ships with messaging functionality, including IM, push notifications, and a two-way feedback channel.

The company says that over 1,000 developers have already implemented functionality from its SDK into their apps. According to an internal study, participants in the beta program saw a 97 percent increase in the average user time spent on the app by 97 percent, and an 89 percent increase in the number of recurring session

Ran Avrahamy, Scringo’s c-founder, stated “We founded Scringo with the goal of helping developers bypass the time-consuming and costly process of creating comprehensive functionality themselves, so they can instead focus on their core app features and monetization.  As evidenced by the strong metrics from our beta program and the number of developers already using Scringo, our solution has been overwhelming successful in achieving these objectives.  We’re excited to now offer Scringo broadly to iOS and Android developers everywhere.”

Mobile developers are a huge market that has attracted both startups and IT whales. Intel recently acquired appMobi, one of the biggest providers of HTML5 development tools.  The company, best known for its mobile-optimized variation of jQuery, has more than 130,000 using its software to fine-tune their apps for other platforms. Terms of the deal were not disclosed, but the chipmaker said did disclose that appMobi’s staff will be kept as is.
