Frozen Shoulder Recovery Tracker (Mobility App)

Frozen shoulder, medically known as adhesive capsulitis, is a condition where the shoulder joint becomes progressively stiff and painful, limiting range of motion in all directions and making simple tasks like reaching overhead, behind the back, or out to the side extremely difficult or impossible, typically progressing through distinct freezing, frozen, and thawing phases that can last months to years. Approximately 2 to 5% of the general population experiences frozen shoulder at some point, with higher rates among people with diabetes, thyroid disorders, or after shoulder injuries, and while most cases eventually resolve, recovery can take 18 months to 3 years without proper treatment and consistent physical therapy. Currently, no dedicated apps exist to help frozen shoulder patients track their range of motion improvements, document daily pain levels and mobility limitations, monitor adherence to prescribed stretching and physical therapy exercises, or provide objective measurements that show whether they're progressing through recovery phases or if their treatment plan needs adjustment.

People need an app that measures and tracks shoulder range of motion in all directions using smartphone sensors or guided photo measurements, logs daily pain levels during rest and movement, records completion of prescribed exercises and stretches with video guides and reminders, monitors functional abilities like reaching, dressing, or sleeping comfortably, tracks interventions such as physical therapy sessions, corticosteroid injections, or hydrodilatation procedures, and generates progress charts showing gradual mobility improvements over weeks and months that provide motivation during the frustratingly slow recovery process.

This represents a solid business opportunity because frozen shoulder patients are extremely motivated to regain function that impacts every aspect of daily living from dressing to driving, the condition's long recovery timeline creates excellent subscription potential with users needing tracking for 12 to 36 months, patients struggle with exercise compliance without accountability tools and visible progress metrics, the market includes millions of sufferers who are often middle-aged professionals willing to invest in recovery tools, physical therapists could recommend the app creating professional referral channels, and the objective demonstration of range of motion improvements provides clear value that justifies ongoing subscription costs while helping patients stay motivated through the long, discouraging recovery journey.
