my phone seems more accurate all around- counts time “awake” in bed as sleep, so you have to manually subtract that yourself- the sensor bar is like a mini rave light, and it gets very mad if you take it off

Not sure if I would recommend, this watch didn’t record my sleep, and the battery died way too frequently

The fit is comfortable, even at night while sleeping.

I have no idea if the sleep indicator is accurate as far as deep sleep.

Sleep tracker isn’t accurate neither is the heart rate monitor

Tracks my sleep and steps accurately, has held up really well for the last 9 months, and I wear it pretty much 24/7

I have had the device for less than a week, so I'm still waiting to see how well it tracks my sleep and other activities.

Product was ok but had issues getting the sleep to track but for a cheaper tracker was decent for price i guess

Sleep tracking stinks

The sleep is extremely accurate from what I can tell

I used this to see my sleep tracking because I did not think I was getting enough sleep

This product isn't how I planned it glitches really bad and don't track my sleep very well very disappointed:(

Not sure if I would recommend, this watch didn’t record my sleep, and the battery died way too frequently

Also I'm not sure how accurate the sleep is

It does a great job tracking steps, light sleep and REM sleep and the app is easy to use.

The fitness program is spot on, the sleep monitoring work very well also

UPDATE: well it doesn't sink with the app well so tracking my sleep isn't great

You have to check the sleep function and alarm through the app

It is easy to use this wrist tracker and I have liked tracking my sleep - especially when I am in a deep sleep vs light sleep.

Love this watch and sleep tracking, accuracy

Some time it gives an accurate sleep time but not always
