I am a doctor in alternative medicine homeopathy I have been using the app since quite sometime to track my sleep pattern as well as my patients have been using it . I have tried Nearly all the sleep apps and sleep gadgets to be worn but I found this app the perfect match and best.About 40% people who enter old age do not get sleep , and another huge percentage of other disorders are stress , allergies , anxiety , fear , ocd, children with allergies, sleep apnea and many disorders can be treated but there was no mechanism to track the difference after treatment but this app seems to solve all.I treat chronic and cancer cases what I have observed in my field Is if the medicines is working properly the sleep is more better and longer. And the restless is less and this app shows exactly that. I hope David you can add one or 2 suggestions so it’s the perfect app . 1 - it will help if A text field is added then I can write a small comment of why sleep was good or not good etc on that day.2- if possible the share the sleep data to another user , always or with permission each time or for n number of days .This helps me to see the patients records .3- a calendar like view to check the week or month . So a glimpse can help to see the pattern .In my clinic we give a chart to monitor this . Thank you for such a good app.
