The latest update causes it to log me out and disconnect the device every single time it is used. When it worked it was great, but if I have to log in and reconnect the device every time I want to use it I will probably throw it away and just go back to timed fasting.

Membership buyer beware! Grounds for class action lawsuit. This company probably should have just let $179 yearly membership fee go rather than risk this review. I cancelled the membership with one day left. I took a screenshot with the website saying I had one day to change my mind. I did not change my mind. I hadn’t used the device in probably 6 months. They decided to charge me $179 anyway. I disputed it through my credit card company (American Express for reference). American Express initially returned the $179 to me. Then a month later I get an email from American Express telling me that this company searched their records and found no evidence for my cancellation request. How can this be? Well, I went back to the website just now (a month later) and now it mysteriously says that they had trouble cancelling my membership. Apparently this message was somehow sent only through the website, and only after they seemingly assured me that the membership was cancelled. This seems to me to be a relatively tricky, sneaky and not good business practice.

Outside of taking a measurement, there isn’t a way to update our fasting start or end time. If I miss a measurement (wake or sleep), my fasting appears considerably longer than it actually was in reality. Instead of the 36 hours, the fast should have ended at 18, and the one I’m currently on would’ve been around 8 or 9 hours.
