Very Cool - Even cooler when there are actual stats

Someone asked for a use-case - ie why would I want this app? Night photography: How still really is your camera for a long exposure shot? Take a measure, adjust as needed.

This is a great app and fun. Would love see some stats that can viewed and saved for later comparison. The Roller Coaster Physics app is along the lines of this app, and now allows you to email a full run of the measurements for later loading into Excel or other app. Looking forward to a new version
