WeLoop Hey 3S Sports Smartwatch Review – Part 2: GPS, Running, Cycling, Notifications, and More

WeLoop-Hey-3S-Review

As mentioned previously I did not have such good luck with smart wearables so far, with disappointing products often with a short lifetime (a few weeks to a few months, and some design issues here and there like an e-Paper display without backlight, a touchscreen display with poor locking mechanism (so it’s activated while taking a shower), unreliable heart rate monitor, poor waterproofness and so on… My main requirements are always-on display, battery life as long as possible, notification support, good waterproofness to do tasks like taking shower or swim without having to remember to remove the watch, among others less important requirements. I mostly gave up on the category for about year, but decided to give it a try when GeekBuying asked me if I was interested in reviewing WeLoop Hey 3S sports smartwatch.  Maybe things have improved since then. I’ve already gone through unboxing and initial setup in the first part of the review entitled “WeLoop Hey 3S …

Mediatek Unveils Sensio MT6381 6-in-1 Biosensor Module for Smartphones

Nearly exactly two years ago, Samsung unveiled S3FBP5A bio-processor for fitness tracking wearables with five analog frontends measuring PPG, ECG,skin temperature, BIA, and GSR data, and that is (or was?) expected in the company’s S-Patch3 health tracker. Mediatek has now come up with something with similar functionalities, but instead of being a standalone bio-processor for wearables, Sensio MT6381 biosensor module is designed as a companion chip for smartphones, and capable for delivering 6 different types of heart and fitness data in about 60 seconds.

Some people may need to frequently measure their blood pressure because of their health condition, but it’s often a cumbersome experience, so they may get lazy, and not do it as often as needed.

Review of Xiaomi Mi Band 2 Activity Tracker

I’ve been using Xiaomi Mi Band 2 for a little over two weeks now, so I’m not ready to report my findings, and the results are mixed. If you are interesting in checking out the accessories, and physical aspect of the watch, feel free to read Xiaomi Mi Band 2 unboxing post first. Since the new model adds an OLED display, let’s first see what options it has to offer. The display is off by default, and pressing the capacitive touch button (please note that it’s not a real physical button, so it won’t work with most gloves for example) will turn on the display for 5 seconds. You can keep pressing to go through time, step count, distance, calories burnt, heart rate monitor, and battery level. Except for time, there’s a icon shown before display the actual value. If you find that the display does not look clear, that’s because despite its IP67 ingress protection rating, humidity made it …

Energympro EP-SH09 Fitness Tracker Review

Energympro EP-SH09 is a strapless fitness tracker with an heart rate monitor and Bluetooth 4.0 LE for synchronization with your smartphone, in the first part of the review, I took some picture of the device, and expressed my opinion about the build quality. I’ve now played close to two weeks with the tracker, so I can share my experience with the device. Bear in mind that this was still considered an engineering sample, so the company will likely on some of the issues I encountered before it ships to the general public or resellers. A capacitive touch area just under the display is used to cycle through 7 watch faces: Time, Date, Bluetooth (Icon will change to a chain when connected), step count, distance, calorie count, and heart rate monitor. It works well enough, but there are a couple of point that you may want to be aware. The display will stay on for about 15 seconds after the last …

Xiaomi Mi Band 2 Fitness Tracker Unboxing

Xiaomi started selling Xiaomi Mi Band 2 fitness tracker with an OLED display last week in China for 149 CNY (~$23), but it can also be purchased overseas with the many online resellers, and one of them, GearBest sent me a sample for review, and sells it for $33.91 with coupon GBMI2 once oversea shipping, currency conversion, and possibly some margins are included. Today, I’ll start by taking some pictures of the devices and its accessories, before writing a review in a couple of weeks after testing the device features and battery life. I received the device in a typical Mi package, and GearBest also included a User service card to encourage people leaving feedback, and helping with returns and issues. That’s the first time I receive this card, so maybe GearBest is trying to improve their customer service. The product is definitely geared towards the Chinese market, as the specifications are shown in Chinese on the back of the package. …

Xiaomi Mi Band 2 Fitness Tracker Adds an OLED Display, Promises 20-day Battery Life

I’m not a big fan of fitness trackers without display that require you to monitor your daily progress on your smartphone, and that’s probably why when Xiaomi released their first fitness band I was not quite as interested, but now the Chinese company has released Mi Band 2 with an OLED display, an heart rate monitor,  IP67 ingress protection rating, and a 20-day of battery life for just 149 RMB ($23).
