Deserves more than "cool" – Vibration Meter, seismograph, seismometer Review

I don't live in an earthquake-prone area, but I still enjoy this app. It records movement data for all three axes and displays them separately, it shows numerical data in case numbers mean anything to you, and probably other stuff that I haven't discovered yet. From what I've seen, the ads that appear aren't as invasive as they can be in other apps. It's also free, so give it a try if you're at all interested. If this review window were not covering the developer's name, I would mention them. Thanks!
