To correlate a smartphone-based assessment of mobility, stability, and posture with those derived from standard clinical tests among a heterogeneous cohort.

Smartphone movement health assessment introduces a new measure of health that helps users analyze and improve their mobility, stability and posture through performance of movements and physical exercises. To verify the accuracy of this measure, the goal is to provide data-driven evidence regarding its accuracy in comparison to gold standard tests for measuring movement health. To address this challenge, the assessment scores will be benchmarked to a set of gold standard tests and sensor metrics for measuring movement health recommended by professional associations such as the American Physical Therapy Association (APTA) or American College of Sport Medicine (ACSM) and found valid in clinical studies , .

Inclusion Criteria:

1. All participants should be able to perform the Smartphone movement health assessment and receive a score for their movement health. This will be evaluated by the research team members during the recruitment process.
2. Ages 18-85 years old
3. Able and willing to give written consent and comply with study procedures

Exclusion Criteria:

1. Pregnant or nursing
2. Skin allergies or irritation that would prevent safe use of sensors described in protocol
