really sensitive, i got readings from people walking up my sidewalk, to my front door. Did not expect that! I wish i had it on when we had a small earthquake off the Oregon coast, but i was asleep and didn't feel it at all. I'll bet it would have registered something. Great app, fun.

Used this app in an odd use case to balance a rebuilt driveshaft on a car restoration. Somewhat a trial and error process of adding weights to part of driveshaft and needed to quantitively measure inprovements while the car is driven while on jackstands. Worked really well.

Agree that it has good sensitivity. Staying at a hotel near railroad tracks, and this one beat out another one I tried.
