Most people will never know this is a smart watch. However, it has the ability to display text messages, calendar reminders, email messages, Facebook notifications, weather and more. It is a nice, subtle way to receive these messages without having to take out your phone, unlock it, open the app and get whatever info you want. The Martian app, which lives on your smart phone, is quite comprehensive and enables significant amount of customization (which apps you want notifications from, what vibration patterns you want for each app, etc.). Battery life for the smart watch portion is about 4-5 days, if you turn it off at night. Charging is done via proprietary micro USB cable. And, this is also an analog watch, with a separate 2 year battery. Other features: LED flashlight, Do Not Disturb Mode, Find my Phone, Notification if you leave your phone behind (leash), multiple languages. firmware update. The watch is water resistant, not water proof. Some reviewers have criticized this, but it's a non-issue for me. Don't shower or swim with it and it will be fine. There are a couple of bugs in the app, which is why I lowered it one star. But I expect that to be worked out with future updates. So far, I really, really like this smart watch. Oh, and it does NOT look like you've strapped an iPod Nano to your wrist.
