The Band bracelet itself has stopped supporting as early as October 2016, but some users have expressed shock and sadness after hearing this news. The comment post on the app download page says:
Since my phone updated Android, Band stopped working completely and couldn't open the app. What's worse, it drained my battery in some way. After I submitted the problem report, I have been waiting for Band's update, but still not. Unfortunately, I am using Band to collect my heart disease-related biometric information, but lost all data because I stopped supporting it.
Microsoft then said that they will provide users with support for downloading data, but the FAQ explaining how to do this seems to have failed.
Microsoft said it will synchronize Band data to active users of Health Dashboard from December 1, 2018 to March 1, 2019.Request a refund. Microsoft offers $19.99 for Band 1 owners and $175 for Band 2 devices.
After the service is stopped, users can still track and track daily health information (daily steps, heart rate, basic exercise), record activity data (running, cycling, hiking, etc.), track sleep and set alarms, but they reset After their Band, they will not be able to set it up again.
