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 Users report crashes, freezes, and outdated UI, plus no background data collection.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No longer updated and compatibility with newer iOS versions (e.g., iOS 11+) is problematic; app may be unusable on current devices.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UI and controls appear outdated for newer iPhone models (e.g., iPhone 5/6) and lack modernization.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.
