Every step tells a story - we help you and your healthcare provider see it.
OneStep is the easiest way to see how well you’re moving. Just place the phone in your pocket and take a 30 second walk. That’s all it takes. No additional hardware, no cameras involved.
Our clinically validated app uses your smartphone’s sensors to analyze your gait in seconds - revealing insights about your balance, recovery, and risk of falls. Whether you’re recovering from surgery, managing a health condition, or just staying active, OneStep helps you track progress and stay connected with your care provider.
Backed by science. Loved by patients. Trusted by leading healthcare providers.
Because we are how we move - and now it’s easier than ever to see it.
Please note: Accessing OneStep is only possible via select healthcare providers. To learn more, ask your provider to contact us by visiting www.onestep.co .
