Appstatics, an iPhone, iPad and Mac application performance tracking service, has been bought and relaunched by Appsfire, which offers a versatile platform for mobile app discovery, recommendation, sharing, promotion and monetization.

Appstatics is essentially a native iOS app (get it here) that was designed specifically to help developers and publishers monitor how well (or poorly) their apps are performing on the App Store.

Appsfire co-founder Ouriel Ohayon tells me they acquired Appstatics from a company called MOS teknoloji after looking for that type of solution (“like App Annie but for mobile”) for a long time.

They were just about to decide to build it themselves when they stumbled upon Appstatics and thought it would make for a solid foundation for the product they needed – so Appsfire went ahead and bought it from its developers.

Terms of the acquisition were not disclosed.

The tool can be used by app publishers and developers looking to track how their apps are doing, compare performance to competitors, but can also serve investors tracking portfolio companies, journalists and bloggers, and so on.

The app has been republished to the App Store and is usually priced $1.99 (it’s free for a week though).

Ohayon says Appsfire will add a lot of new features to Appstatics in the near future.

Appsfire raised close to $5 million in funding from investments firms like Lerer Ventures and Idinvest Partners, as well as a group of angel investors that includes Meetic founder Marc Simoncini, Xavier Niel and Fabrice Grinda.
