Is there any way to get a breakdown of how many of the downloads for an app have been for each specific device? I'm curious what devices my apps get used on so I can concentrate development effort in that direction.
currently the only way to get that info would be to upload several versions of your app to the store (one for each device (group))
(well alternatively you could also track usage by communicating the uniqueId + deviceType to your server, but when you do that you should at very least mention it in a privacy policy)
