Features & Capabilities

iSeismometer turns your iPhone or iPad into a live seismograph using its built-in accelerometer. View three-axis ground motion, scroll through up to an hour of history, analyze frequencies, and detect tremors with adjustable STA/LTA sensitivity. Automatic recordings can be browsed by day, reviewed for events, and exported as CSV or raw files.

Compare activity with live USGS earthquakes on a globe, or stream multiple devices to a Mac over Wi-Fi for a home seismic station. Designed for education and experimentation, iSeismometer is ideal for observing footsteps, machinery, traffic, and nearby vibrations—not a replacement for official earthquake alerts.

User Reviews

iSeismometer is praised for its sensitive readings and advanced features like FFT analysis and data export, but it appears abandoned with compatibility and stability issues on modern iOS versions. Users report crashes, freezes, and outdated UI, plus no background data collection. Its core functionality remains compelling, but lack of updates undermines reliability on current devices.

Pros

Very sensitive and accurate accelerometer readings for seismology.
FFT analysis capability and data export options (including UDP with low-pass filtering).
Lightweight footprint with a small storage footprint on the device.
Unique, innovative concept as a mobile seismometer that users appreciate.

Cons

No longer updated and compatibility with newer iOS versions (e.g., iOS 11+) is problematic; app may be unusable on current devices.
Frequent crashes and freezes; the app becomes unresponsive or locks up after use.
UI and controls appear outdated for newer iPhone models (e.g., iPhone 5/6) and lack modernization.
Lack of background operation/multitasking support limits continuous data collection and usability.
