The Gait & Balance App (G&B App) is a mobile application that uses built-in smartphone sensors to capture movement data during basic standing and walking tasks. It is designed for use in supervised settings by professionals familiar with balance and gait observation protocols. The app does not provide any clinical decision-making guidance or diagnostic interpretation.
Movement challenges, such as reduced balance or altered walking patterns, may be observed in various populations. However, clinical assessment tools often rely on basic, low-resolution methods.
The G&B App offers a structured interface for capturing motion data using smartphone sensors during a predefined set of standing and walking activities. It is intended to support observational gait analysis, but not be relied on to detect, diagnose, or monitor any health condition.
The App is suitable for trained professionals wishing to conduct structured movement assessments under controlled conditions. The user assumes full responsibility for any use of the App and for compliance with local research, clinical, or privacy regulations.
The app is intended only for structured movement assessments by professionals. It does not interpret data or suggest any clinical actions.
The G&B App captures inertial motion data during the following six standardised tasks, based on widely used clinical balance testing protocols:
Some metrics show good reliability for research use (not diagnosis), and others are included for transparency only. Gait and balance metrics such as acceleration patterns, periodicity, and step symmetry may be estimated. These metrics are not validated for clinical use and should be interpreted cautiously, in research or exploratory settings only.
Reliable Metrics
Postural steadiness, postural steadiness AP, postural steadiness ML, walking speed, periodicity, step length, and step time
(ref: Rashid and Olsen)
Less Reliable Metrics
Step length variability, step length asymmetry, step time variability, and step time asymmetry
No interpretation, risk classification, or threshold is provided by the App. It is the user’s responsibility to understand and interpret all data.
These peer-reviewed studies reflect independent academic evaluations. They do not imply regulatory approval or clinical endorsement.
Some research teams have reported their independent use of G&B App data in non-diagnostic studies.

The G&B App is compatible with iPhone 7 or newer. Functionality on older devices or unsupported platforms is not guaranteed. No support is offered for hardware or software modifications.
The G&B App is provided as-is and without any warranties. It is not intended for clinical, therapeutic, diagnostic, or life-critical purposes. The developers, contributors, and affiliated institutions accept no liability for any decisions, outcomes, or adverse events arising from the use of the App or its outputs. By using the App, you acknowledge full responsibility for all actions and data practices.
The G&B App does not collect, store, or transmit any personal or movement data to external servers. All data remains local on the user’s device.
No login or personal identifiers are required.
The App may request permission to access:
No data is used for tracking, advertising, or analytics.
No personal data is accessible to the developers.
Users are responsible for any exported data and for complying with local privacy laws.
Users have full control to export or delete their local data.
We'd love to hear from you! Please reach out at your convenience so we can discuss your project.
