Totally unreliable
App has worked properly one day out of the first week Ive had it. Band disconnects when you least expect it (like at the start of an 8-mile hike) and does not sync properly when you finally get it to connect later. Hike and thousands of steps, of course, go unrecorded. Sleep function has not yet worked a single night. You get what you pay for -- luckily my Mi band was a gift...
