Over engineered
One benefit is that the app helped me get my head to 45 degrees.
One weakness is the written instructions: they fail to mention that you must turn the head *before* lying down slowly.
I gave up on this app after one day and made by own “hands free” timer from a free HIIT app. Now I can listen to a podcast while the free app speaks instructions. Much more relaxing.
Response from developer
Thanks for the feedback. We developed this app because I found that when I adopted the approach of using a simple timer and listening to audiobooks that I tended to unconsciously relax my posture thereby reducing the benefit gained from the exercise. Instead I found it better if I remained engaged with the exercise as this helped me maintain the recommended 45 degree angle which is what the app was designed to do. While I was using the app I still listened to my audiobooks which certainly made the time fly past and is why we added the 'change position' chime. Once again thanks for the feedback and I wish you a speedy recovery.
