SimpleAcceleration
Walking time, speed & motion
Free · Designed for iPad. Not verified for macOS.
SimpleAcceleration helps you measure and record straight-line walking. Review walking time, speed, estimated steps and acceleration waveforms alongside participant names, dates and notes. The app and all features are free.
PREPARE A MEASUREMENT
Choose a course of 5–50 m and a separate run-in of 0–5 m, in 0.1 m increments. Record the participant, walking instructions, walking aid and notes. Illustrated instructions explain device positioning and the course.
USE ONE OR TWO DEVICES
With one device, hold it steadily in front of the chest or abdomen and choose manual timing or AR distance measurement.
With two devices, hold or secure the measurement device at the waist and operate it manually from the other device. Tap Start as the participant crosses the start marker and Stop at the finish marker. With no run-in, start as walking begins from the start marker. Update both devices to the latest available version and check that their versions match in Settings. On-screen and audio guidance are available in Japanese and English.
REVIEW RESULTS AND WAVEFORMS
See walking time, mean speed, estimated steps and cadence. Details include mean gait-cycle duration, three-axis acceleration RMS, autocorrelation (AC), harmonic ratio (HR) and gait-cycle duration variability (CV). Each measure shows its calculation status, reference-value limitations, reasons it was not calculated, and the cycles or intervals used.
Review saved video and waveforms, and save edits to contact times and analysis intervals as revisions while keeping the original.
Short walks may contain too few cycles, resulting in short-segment estimates or unavailable measures. Handheld device-axis analysis is distinguished from waist-mounted trunk reference measures.
FOLLOW THE SAME PARTICIPANT
Select a participant and previous conditions for another measurement. Search records by name, date or notes, view a participant's history and compare two records. Measures that cannot be compared show the reasons, including differences in conditions or analysis methods. Numerical increases or decreases are not assessments of clinical improvement or deterioration.
SAVE, SHARE AND BACK UP
Records and waveforms are stored on the device. There is no automatic deletion based on record count; free device storage is required. Export CSV, PDF reports, JSON backups, waveform images and videos. Video files are not included in JSON backups, so export and retain them separately. Previously saved measurements and analysis versions are preserved and are not automatically reanalyzed.
BEFORE USE
For one-device mode, keep the screen facing you and the rear camera facing forward. For waist mounting in two-device mode, secure the device vertically with its top edge upward, screen facing outward behind you and rear camera toward your back.
AR distance is experimental. Validity of acceleration, step estimates and detailed analysis in real walking is still being assessed. Treat results as reference values. HR means harmonic ratio, a measure of within-cycle symmetry; it does not mean heart rate. The app is not intended for diagnosis, treatment decisions or fall-risk assessment. Continue normal supervision and assistance.
