My favorite aspects are ease of putting in a menu, picture handling and the exercise library (great also for browsing to find e-cises I am not familiar with as well as different positions for e-cises I know). Being able to pull up a community menu (low back pain) which I know works well and have it instantly available saves time. My clients have enjoyed using PTX over the past several years on all platforms: phones, ipads PC's, etc. Client interface is excellent. “ -Heidi Loh
