About Us

Our Vision + Our Mission

appbackr’s mission is to index the world’s apps, enabling app users to make informed and inspired decisions, and making apps accessible to everyone through the App Anatomy™ Project.

Our Story

In early 2010, appbackr created an innovative marketplace to help developers raise funding and to build attention around their apps and app ideas. The crowdfunding platform also enabled app-savvy users to profit from the success of good apps, once they hit the app retail stores. The appbackr Marketplace earned numerous awards including the PayPal X Developer's Challenge Award.

“Marketing and distribution are some of the biggest challenges for developers, something appbackr can help address.”

The New York Times

As Marketplace gained thousands of registered users, we wanted to find a way to identify the most promising apps to help them raise more funds for marketing by better informing our users’ purchasing decisions.

In August 2011, we began to build appscore Xchange, a distribution service based on our machine-learning algorithm. The mechanism looks at publicly available data to objectively score apps, and identify apps that deserve to be discovered. Our data sets include information from 13 countries’ Google Play stores, Apple via their enterprise feed, Chrome, Firefox OS, Blackberry and Windows Mobile data.

“appbackr has added a new tool, called Xchange, that serves as a data analysis tool [that] can optimize when and how developers use the wholesale services and help get developers paid.”


Within the first few months of the new project, companies like Motorola and Intel approached us to use the appscore to identify apps to either feature or port to a new platform. We realized that the appscore could become an important tool for companies in the mobile ecosystem.

Also in August 2011, we hosted our now-annual App Retreat in Napa Valley, followed by a wine-tasting reception at Hall Winery in St. Helena. The invitation-only event brings together a small gathering of thought leaders in the app economy. Speakers on the presentations, panels, and discussions join as attendees with the idea that everyone is a relevant peer. The founding purpose of the App Retreat is to allow leaders and innovators in the app space to engage in great content on topics around app distribution, discovery, and ecosystem development.

At the end of 2012, Xchange allowed partners such as Samsung, Amazon, and the new OS Tizen to view Android apps next to their appscore, and make decisions based on the score. The appscore Xchange developed huge growth, adding 13 ad network partners.

"Using this methodology allows appbackr to discover great apps that are typically not readily exposed to customers because they are not present on top 10 lists for apps."

Wall Street Journal

At the fourth annual App Retreat in August 2014, we announced Version 2 of our appscore. This version incorporates our App Anatomy™ Project, a collaborative effort to catalog the world’s apps based on three components of an app: its technical performance, behaviors, and user sentiment.

These components are measured by appbackr internal analysis and tools: gesture-mapping tool, user sentiment analysis, curated behaviors.

In late 2014, we began developing several products that use our data. Our team is now building the next version of the appscore, which will be released through various API services to our partners and consumers.

“appbackr’s new scoring engine may help good apps emerge from the muck...The system applies a numeric score to Android apps, which could help people find great apps lost among the sometimes hundreds and thousands of options in the stores.”


We encourage you to have a look at our FAQ which addresses all the details both large and small.

appscore is a quality score which drives discovery, distribution, and incentives for developers' apps. It is the core of what appbackr does. We use a machine-learning model to score every app on major platforms including Android, iOS, Chrome, BlackBerry, and Windows Mobile. It's our product used by consumers, developers and partners.

appscore is the foundation of Xchange which provides incentives and rewards to developers based on a ratio between the appscore and its current market performance. Based on this ratio, developers receive incentives to port apps and to promote their apps on partner sites operated by carriers, OEMs and other third parties.


Xchange provides a platform to developers to receive offers from stores and platforms to port their apps. Based on the appbackr appscore, the higher the app scores, the greater the incentives to port. Developers also can promote their app on carriers and OEMs based on the score of the app. appscore looks at reviews, stars, app traction and other factors to score every app on iOS and GooglePlay from 0-10. The higher the number, the better the app and the better the reward.


Marketplace has helped developers crowdfund over 1 million dollars to develop and market their new apps. Developers build a distribution network around their app campaign page through online email, social media and blogging and offline communication.
