This is not a very smart watch. It disconnects from the app on my cell phone quite often which is a nuisance. The weather was NEVER correct. Even though it was connected to my phone, it never showed the same weather information as my phone did. I don't know where it was getting its information from, but it was not from the area I live in. Now it doesn't give the weather at all.... just shows a question mark which is better than seeing the wrong information. The heart rate app was always higher than my actual heart rate and the fact that I could have the watch off of my wrist and laying on my bed and it would register a heart rate for my bed makes me believe that function is bogus. The Find Phone function works about 1 out of 20 tries (or less) even if the phone is close to the watch. If you're buying this to monitor your sleep... don't. It's not accurate at all. I can sleep for a solid 8 hours and it will say I slept for 3. I don't bother with it anymore. The step counter doesn't work well around the apartment. I can walk from the bedroom to the bathroom and back in the morning and no steps will be registered. (No, I don't levitate.) On the days that I knit, I reach my step goals sooner than the days I actually get up and walk.
The shutter and music functions worked when I tested them, but I don't use them so I don't know if they work all the time. The stopwatch works but drains the battery like crazy!
I kept this watch despite it not living up to its description, because the news function works most of the time so I can receive text messages while at work without checking my phone and it had a way longer battery life than high end "real" smart phones. Also, I can set reminders to drink water and have five different alarms set for the day.
