I created Udid.io together with my team called MacBuildServer.<p>Udid.io has an API, so you may generate link for your beta users and grab theirs devices UDIDs to set up properly mobileprovision configuration for your iOS app builds.<p>I want to hear from you. We've got a number of API users and I want to know if there any more features you would like to have in this tiny web-app...<p>Additionally, I want to hear what we can improve, or any ideas regarded to monetization of such service. Now it's absolutely free, but uses Google AdSense and it makes UDID.io looking not good. Probably you could recommend what to add to make us able to remove Google Ads ;)
