I noticed recently that you can now look at stats on your app downloads/installations. Is there any documentation on this yet? Some of it's a little opaque without being able to directly compare numbers from one graph to the next.
Stats page should be pretty self-explanatory. If you don't understand some parts of it, feel free to reach out to me directly with your app link, and I'll help you to decipher it, and add to a common FAQ, if needed.
