And on the Mercalli scale, it says IV. So please work on the sensitivity of the detections. **Developer response:** Thanks for your feedback. Seismometer uses highly sensitive phone motion sensors calibrated with science-based and official reference values, so even very small vibrations can register when a device appears still. For the most accurate results, the phone should be placed flat on the floor (be aware that even wooden floors can transmit vibrations) and left completely untouched, ideally while charging. We’re continuing to refine sensitivity handling to make readings more intuitive in everyday use. ### 3/5 — Good but drains battery fast *2025-06-24* Good app, but drains battery fast. It would be nice if this can run as background app so that other work is not interrupted ### 3/5 — Pls add Richter scale. *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? ### 5/5 — Helps a lot after Bangkok earthquake *2025-04-16* 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. ### 5/5 — It was great, but always kept sending me a two magnitude earthquake *2024-12-08* Like every time I would set it off it would show a two magnitude earthquake, and Flagstaff usually gets Shindo three upper **Developer response:** Thank you very much for your rating! Seems there is slight movement of the surface you have it on. Try the floor. Movements are defined from each scale in the form of acceleration. ### 1/5 — Why *2024-12-06* This app is a joke. Doesn’t work the way you think it’s going to **Developer response:** Hello there. It is clearly stated that the free Seismometer app is intended to be used as an instrument of visualizing movement and has live alerts according to 4 types of major earthquake movement scales. I can’t really say what did you expect, expectations can be misleading some times. You could always contact support. ### 1/5 — Alarm stuck on *2024-10-30* Please get the alarm off update etc **Developer response:** I am truly sorry to hear you encountered an issue with Seismometer app. Unfortunately your issue is isolated and I can not help you unless you contact Support through the app. Thank you ### 3/5 — Works good but notifies you only once at a set time *2024-03-23* 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 **Developer response:** The notification acts as a reminder to open the app. If the app is not open and monitoring for earthquakes (movements) cannot alarm you about an earthquake. That is why is called Live Monitor. ### 3/5 — Works good but notifies you only once at a set time *2024-03-21* 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. **Developer response:** The notification acts as a reminder to open the app. If the app is not open and monitoring for earthquakes (movements) cannot alarm you about an earthquake. That is why is called Live Monitor. ### 1/5 — It doesn’t even work *2023-09-24* It doesn’t do anything! Last night we got a intensity 4 or a shido 3 It was super terrifying. I thought they were warn or something. all it does is it tests for some reason **Developer response:** Hello, I am really sorry to hear that you were terrified from the earthquake. Was the app monitoring for earthquakes? Did you press the play button after you have set up the intensity and the scale? There is a specific procedure that is outlined in the app’s help and in the app’s website. Please make sure you have done all that and please remember that you can always contact support within the app. Thank you ## Frequently asked questions about Seismometer ### What does the Seismometer app do?
