User reviews

Needs much work

As of this review, faults are limited to the western USA. No faults in Alaska. Only the major faults have been digitized. Zooming in does not reveal more. Pretty disappointing.

Having read the developer’s response, I agree. But then the app needs a new name.

Still disappointed.

Response from developer

This review is not fair or accurate. 1. The app description has always made it clear that the app covers the continental United States. The continental United States does not include Alaska and Hawaii. 2. The app has always covered the continental United States, not just the western states. 3. The app description has always made it clear that the app shows the vast majority of faults the USGS classifies as “Historic” (active in the last 150 years) and “Holocene to Latest Pleistocene” (150 to 15,000 years) and that it does not show faults classified as “Quaternary” (15,000 to 1,600,000 years). The app description has always been accurate. It appears that the reviewer did not read the description before purchasing the app.
