Our thanks to Tapstream for sponsoring MacStories this week. Tapstream helps app developers earn more from their apps.

For those of you who don’t advertise your app, Tapstream is completely free. You can embed it in your website to understand which referring sites and which landing pages are responsible for the biggest share of installs. Alternatively, use Tapstream’s URL shortener to get this same data from social networks, email or anywhere else on the web. If you decide to spend money on mobile ads, Tapstream is partnered with the best ad networks out there to help you advertise and make sure you’re not double-charged for your users.

Beyond just telling you how your users are getting to your app, Tapstream keeps track of exactly how valuable each channel is. Automatic In-App-Purchase reporting tells you where you get the most of your revenue from. Add to that a bevy of features like device-aware shortlinks (that discriminate between iPhone, iPad and Android visitors to send them to the correct destination), cohort tracking and integrations with HootSuite, KISSmetrics and MixPanel.

Tapstream is already on your iPhone in many of the apps you use today - it should be in your app too.
