Review summary

The app is easy to use with adjustable sensitivity and offers peace of mind for some users, but it suffers from serious reliability issues: frequent false alarms, failure to alert during real earthquakes, and a lack of critical scales like Richter or Mercalli. Users also report limited, non-live notifications (often only once daily) and confusing setup for filtering stronger quakes. Support and internet connectivity complaints exist in some reviews. Overall sentiment is mixed: positive on usability, but problematic in accuracy and alerting, with key feature requests unanswered.

Pros

Adjustable sensitivity / ability to change sensitivity
Easy to use
Provides peace of mind for some users

Cons

Unreliable detections with frequent false alarms and failure to alert during real earthquakes
Missing scales (no Richter; requests for Mercalli)
Alerts are not timely (limited or daily notifications, no live alerts)
Setup/configuration is confusing or difficult to tailor to filter stronger quakes

2026-04-20	Pl*****	When my device is s completely still, the shindo scale says 3. And on the Mercalli scale, it says IV. So please work on the sensitivity of the detections.

2025-04-23	"…*****	I think this app is mid, because there is no Richter scale, which makes it harder to use than other apps, and I put my gadget on the bed and it kept showing me there was an earthquake every time. On the ground, it showed me the same results. It was not shaking at all. What plans do you have to fix this?

2025-04-16	Na*****	Really gives me peace of mind when i sleep. Easy to use and also really nice that you can change the sensitivity. Youre a life saver.

2024-03-23	Lu*****	Works good but notifies you only once a day, at a set time. getting notified tomorrow morning at 10 AM about an earthquake that happened today, it is not helpful. it would be great if you could set it to alarm you Live, when an earthquake happens . I appreciate the app but could be very very helpful
