Almost $40 billion is spent on in-office post-surgery rehab, sports therapy, and chiropractic care in the US, yet there is almost no support for patients when they go home, despite the importance of at-home exercise to recovery.

So I made Koach--a mobile "tele-health" app platform allowing physical therapists to help improve their patients’ at-home exercise compliance and form through mobile video guidance, feedback, and progress analytics.
