Update 3/3/2026 Developer updated me on things they have added to their app so it is so ,check improved now, that I decided to change my rating to a 5 star . Too little is shown on the non-subscribers of this app to know what what is really missing from not being able to see what subscribing to this app really shows .

This app has potential & the developer is very responsive & working to increase the capabilities of the app. It’s impressive the developer actually responds. These are the things needed to be useful to me; Actually SHOW the fault lines. Show ALL levels of quakes; don’t limit to just those 2+. Be sure the level allowed matches in both map choices & actual settings page, Let the user sort by state & dates. I want to be able to see every quake in an area, w/date & size. Thank you.

Developer Response
Edited: Hi nonfunc, Thanks again for the thoughtful feedback we’ve addressed the items you listed in the latest updates.Fault lines are now fully visible with detailed fault line layers.You can now view all earthquake magnitudes (no longer limited to 2.0+), and the filters are consistent across map views and the Settings page.We improved the earthquake feed so you can see every quake in an area with date/time and magnitude, with better browsing and filtering for faster reviewing.We also rebuilt the app end-to-end and added major new features, including I Felt an Earthquake, Family Group (invite code, safety status + chat), and a location-based Risk Calculator that lists your 5 nearest fault lines and estimates risk using nearby earthquake magnitudes.Please make sure you’re on the latest version to get all fixes and improvements.
