I have MyShake but I also have an app simply called “Earthquake” that pops up pretty fast with what the magnitude is. It doesn’t give any pre-alerts or anything, but I like it anyway because it showed up within 30 seconds of the quake (I’m in Sunnyvale for reference) and when I tapped on the notification, it told me it was a 4.0 based in Millbrae and provided a map.

About five seconds after it stopped, my dog started barking. A bit late, sweetie! My 9 year old near me on the couch felt it, but my 7 year old in her room didn’t. But it’s possible she was just oblivious.
