Unhappy with this app - when I set up my account was delighted to be given 2 weeks access to "Huckleberry plus", and the app encouraged me to complete a sleep questionnaire to submit for analysis and personalised recommendations. However after completing the (long) questionnaire the button saying "submit for analysis" changed to "upgrade for analysis" - I needed to infact pay for the addition, "premium" level subscription. I don't mind paying for a service but this is misleading.
