App store GetJar has released a new conversion tool to help developers of all open platform stripes track user engagement. It’s a simple, automated process that tells developers whether a user who downloaded an app has actually opened and engaged the app. All that incoming data can then be broken down by phone, country and even network, becoming a potentially powerful diagnostic tool for developers who need to know how their apps are operating across various devices and networks.
This is how it works: a developer signs up for an account on GetJar. The developer adds GetJar’s conversion code into their app (it’s free), which is then published on the site. When a user downloads and then opens the app, the app pings GetJar about the event.
