Smartphone-based mobility assessment

Objective gait and mobility, from the phone already in their pocket

Sentinel by Mahalo Health is a smartphone-based mobility assessment platform. A patient carries their own phone, takes a few steps, and Sentinel captures objective gait, balance, and functional mobility information from biomechanical data — no wearables, no sensors to ship, no calibration. Qualified care teams review the results; clinical interpretation and decisions remain human-owned.

One connected platform

Everything the assessment feeds into

Four coordinated surfaces carry movement information from a patient's pocket to the point of care.

Measurement

What does Sentinel actually measure?

Sentinel is designed to collect gait parameters, standardized functional assessments — including Timed Up and Go and balance tests — range of motion, and patient-reported outcomes, in the background or on demand. Together they form a longitudinal mobility review: not a snapshot from a single visit, but movement as it actually happens, day after day.

From measurement to action

Clinical signals, kept in human hands

Balance. Stamina. Stiffness. Sentinel is designed to turn raw movement data into fall-risk visibility for qualified teams — with timely notifications, draft notes, and preventive intervention workflows. The platform surfaces the signal; the clinician owns the interpretation and every decision that follows.

Foundational science

How can a phone measure movement this precisely?

Sentinel is built on movement data, sensor innovation, and applied AI — a foundation for objective movement information, validated against gold-standard methods.

01

One-of-a-kind database

A large, tagged database of gait data, ADL codes, kinematics, and clinical cases informs objective movement information.

02

Motion SDK & API

Smartphone sensors provide continuous, battery-efficient movement data streams, translated into structured mobility signals.

03

Care engine

Sentinel is designed to translate movement data into clinical decision support signals — from balance to stamina to fall-risk visibility — for human-governed teams.
