StillMetric: Motion Journal

Turn a few quiet seconds into a clear, repeatable motion record.

StillMetric uses your Android device's accelerometer and gyroscope to record a guided 12-second hand-motion observation. Choose Rest, Posture, or Task, follow the same setup each time, and review a descriptive signal trace on your device.

WHAT YOU CAN RECORD
• Motion amplitude
• Dominant frequency in the 3–12 Hz band
• Signal quality and handling-artifact indicators
• Optional context: medication timing, sleep, stress, caffeine, recent activity, and a personal note

BUILD YOUR JOURNAL
Save only the observations you choose. Reopen any entry to review its trace, measurements, protocol, timestamp, and context. Delete one observation or clear the complete local journal whenever you want.

COMPARE LIKE WITH LIKE
StillMetric compares recent sessions only with the same protocol. Frequency, amplitude, and quality changes are described without labeling a change as better or worse.

EXPORT YOUR RECORD
Create a CSV or paginated PDF for an observation through Android's system document picker. You choose where the file is saved.

DESIGNED FOR CONSISTENCY
The in-app guide explains how to repeat the same posture, phone placement, timing, and context. Signal-quality and handling-artifact indicators help you recognize recordings that may be less consistent.
