Konitee Heart Rate Blood Pressure Monitor is water-resistant, but it is not good enough for swimming or diving. Unless you keep it closer, it won’t give you the best tracking results. What makes this smart tracker worth the asking price is the sleep monitor, which, by default, is set to work between 22:00 hours and 08:00 hours. The sleep monitor can track deep sleep and even identify all of your light sleep hours.

Monitors Sleep

This fitness tracker does an amazing job with its sleep monitor. The feature tracks both light and deep sleep, while recording your progress to give you a precise status.

Blood Pressure Tracker

Konitee Blood Pressure Monitor tracks regular activities, including distance walked, steps taken, and calories consumed. And then it displays the results in the app.

Notification System

If you are the kind of person that relies on reminders to live an organized life, Konitee might likely be your wrist friend, thanks to the notification system. It has SMS and call alerts, and it can even remind you to take your medication, go for a drink, or attend a meeting. 


  • It is compatible with many Android and iOS smartphones and tablets
  • Because it is a multifunctional device, it can monitor almost anything you want
  • It is the only activity tracker with electrode and photoelectric technology, making it a good option for testing blood pressure.


  • Battery misbehaves, a lot
  • The user interface is awkward, completely prehistoric
  • Requires charging as soon as the battery hits 25%
  • Risk of losing data if battery runs out

LetuFit Plus might just be the best fitness tracker with heart rate for people that love Smartwatches that integrates tons of features into a single wearable. Weighing about 30g, this pulse rate monitor is so lightweight that you won’t even notice you are wearing it. As for the battery, only 2 hours of charge is enough to make the watch function for a week and a day.

Multiple Activity Tracking

LetuFit Plus is a high-end device designed to monitor multiple activities. From yoga and dancing to hiking and trail running, this device can track just about any activity you can think of. Also, it monitors your heart rate and displays the results on the LetuFit Mobile App.

Data Synchronization

Waterproof fitness trackers are great. But many of them are designed for men. LEMFO is different because is solely for women that love to set and monitor their fitness goals.

Another important feature of LEMFO P1 Fitness Tracker is its ability to measure heart rate. It has a high-tech, high-performance central processing unit that detects blood pressure and returns accurate and reliable results.

  • While the battery doesn’t last a year like Garmin, I’d say the device has a good battery life
  • The battery charges very fast
  • It is both dustproof and waterproof
  • Good, solid design


  • Although the design is solid, the tracker doesn’t have a good battery life

LYOU X5 Plus HR Fitness Watch is what I like to call a private health assistant, and pretty much the best alternative to a dedicated personal trainer. Designed to motivate you towards your fitness goals, you can use this device to track just any activity all-day long. It tracks steps, sleep status, distance, and calories burned pretty well, so I would say it is worth the asking price.


It is good that the LYOU X5 HR Fitness Watch supports call and text notification. But not every person loves this feature. If you don’t like getting call or text alerts all the time, simply long press the touch button, for about 5 seconds, to turn off the notification mode.


LYOU X5 HR Fitness Watch is waterproof, so it is suitable for swimming. To confirm this
yourself, submerge the watch in water for at least 2 minutes. Notice that it doesn’t break down, as it is indeed waterproof.


  • Works well for adults as well as for kids
  • It is an affordable fitness tracker that works as expected
  • It always lights up, making it very easy to read
  • This fitness tracker turns green after it’s fully charged


  • This one has minimal instructions, so a lot of things are difficult to figure out
  • LYOU X5 Plus doesn’t display as accurate results as you’d expect
  • Also, the tracker is a lot thicker than expected
  • The heart rate monitor could use some help as it is not accurate
