ZeFit4 is a stylish activity tracker with color touchscreen that tells the time, tracks steps, distance, calories burned and sleep quality.

From ZeFit4 free mobile app, you can choose a watch face from a variety of designs, set daily goals and reminders but also monitor your results on a daily basis. The app helps you to set-up a fitness routine, giving you the possibility to adjust your goals and check your results on a daily basis.

Suffering from a lack of motivation? If you have been inactive for too long, ZeFit4 “Inactivity Alert” encourages you to move about throughout the day with a gentle vibrating reminder.

When synced to a smartphone via Bluetooth, ZeFit4 shows notifications of calls, SMS, emails, calendar events and social media activity.

ZeFit4 gives you the ability to control your music and take pictures from your watch, without having to look at your phone.

In addition, ZeFit4 features an Anti-theft alarm that alerts you when your paired device is too far away and a “Find my phone” function that helps you to track it down.

Staying connected has never been easier.

I like my Krono‘s. I like this system to be a bit easier when it comes to checking messages not sure how to do it the same every time. Love the HR feature in the many different faces. Nice and light!

Major problems with time

This app, or the watch, clearly has problems with time. Heart rate records show up in the future. Oftentimes there are two heart rate records for the same time period. My guess is that it is a time zone problem, but that is only a guess.

Update: I am not sure where they get their weather information from, but it is bad. If you choose the manual entry in the settings, it always says “Please input a correct city name.”

Update 2: now seems to have disappearing steps. On first glance on a day, the steps will be there only to disappear a half second later, dropping to zero.
