You are of course free to not use MyShake. The project makes no guarantees of efficacy or advance notice. If your bar is "it must work perfectly" you probably won't be satisfied with any earthquake notification or prediction tools for many years to come. That said, this app provided value to many people during this quake, and likely has access to a much larger number of sensors than any other providers that the HN ecosystem seems to know about, so it's unlikely there's a magical additional service out there that's astoundingly better than this one. But you're certainly free to uninstall the app and dis the company for not being perfect, that's your choice to make. I'm happy they are doing the work they are doing and looking forward to them continuing to get better, as innovative technology products frequently do.
