## What is FranjasQuakeDetector?

Franjas QuakeDetector — Seismograph for iPhone

Turn your iPhone into a precision seismograph. Franjas QuakeDetector uses the built-in accelerometer to measure vibrations in real time and displays them as a classic three-channel seismograph (X, Y, Z axes).

Features:

• Live seismograph display with continuously scrolling traces
• Record vibrations and save them for later analysis
• Detailed statistics: min, max, average values and peak magnitude per axis
• Scrollable timeline for saved recordings
• Export recordings as CSV or JSON for further analysis
• Clean, minimalist design inspired by classic seismographs

Use cases:

• Detect and document vibrations from construction, traffic or natural events
• Educational tool for physics and earth science
• Measure structural vibrations in buildings
• Fun science experiment for curious minds
