Head-to-head comparison
Nymbl is a consumer-facing balance training app. It guides users through short daily exercises designed to improve balance over time. Able Assess is a clinical screening tool. It captures four objective, sensor-based functional health metrics, scores them against normative data, stratifies risk, and routes the result to the care team. Nymbl is an intervention. Able Assess is the screening that tells you who needs an intervention and whether that intervention is working.

Category
Clinical falls risk screening (objective measurement and risk stratification)
Balance training program (consumer wellness exercises)
Primary purpose
Screen, stratify and track falls risk with objective data
Improve balance through daily exercise routines
Data output
Four objective metrics scored against age- and sex-matched normative data, with longitudinal trending
Exercise adherence and self-reported balance confidence
Clinical defensibility
Peer-reviewed metrics, FDA listed, CE marked, aligned to NICE 2025 guidelines
Consumer wellness positioning, not a clinical screening tool
Staff involvement
Any staff member runs a five-minute screening, no clinical certification required
Self-directed by the resident or client, minimal staff involvement
Operator visibility
Risk banding dashboard with population-level reporting for operators and payers
Individual exercise adherence reporting
Care plan integration
Automated risk banding routed to the care team, EHR and OASIS integration-ready
No direct care plan integration, sits alongside the care workflow
Payer defensibility
Objective data trail for HHVBP, VBP and regulatory reporting
Wellness program, not typically accepted as clinical evidence by payers
Why screening comes before exercise
Multifactorial falls risk screening outperforms single-test approaches in predicting falls in older adults.
