truefree Smart Watch for Men Women with Bluetooth Call 1.96" Full Touch Screen Fitness Tracker with Heart Rate Blood Oxygen Sleep Monitor, IP68 Waterproof Activity Tracker for Android and iOS Phones

This watch puts everything at your fingertips and paired with the APP has historical and robust connectivity features! I am loving the watch.From the moment I put it on, the watch has been incredibly comfortable for me, especially with the band allowing very small incremental size changes. The screen is crisp, clear and responsive. [Apologies for how much I wrote here! I was keeping notes for myself and turned that into this! There is so much detail about what this swatch does, that I don't even cover it all!]I was happy to find that there are many things this watch does well, including: tracking sleep, periodic and on-demand blood oxygen saturation readings, and displaying continuous heart rate, as well as displaying all the metrics daily and historically. Showing HR and HR zones during exercise/training on the watch face is done simply. The APP allows a mostly intuitive interaction with everything. Receiving texts and seeing who is calling you (if in your synced contacts) without taking out your phone is a plus. The ability to exchange watch faces on the fly from the app and phone is nice (though I don't seem to be able to store all MyDial faces on the phone, still figuring it out.) Importantly, no subscription to see and access your own data and it has LOOOONG battery life (its Day 9 and I am at 43%!!!!).I should note that I am an exercise physiologist and athlete and I value having easy access to my training and recovery information. I like being able to assess my fitness and my state, and I like to challenge myself and see if I have maintained and improved. I typically use a chest strap connected to an APP to track exercise, a sleep APP to track sleep, and a separate device for measuring blood oxygen saturation. So, it was nice to have all these together in one place on the watch. In addition to the health and fitness options, the watch has lots of other functions.The watch operates smoothly, with down, up, left and right swipes bringing up the different screens, some of which have additional swipe screens, which are indicated on side (up/down) or bottom (left/right) when available. By default, the screen stays lit about 10 seconds without interaction, which has been plenty of time to see or start to navigate to what I need. This can be set to 5, 10 or 15 seconds in the swipe right menu under “Settings” (at the bottom of the menu). Clicking the button on the watch takes you up one level or the watch face.If I swipe down there is a menu with basic control option buttons (such as phone, menu list style, don’t ring, screen brightness, wrist flick activation). There is a left-swipe screen indicated and if I then swipe to the left…there are option buttons to change the watch screen’s brightness, engage a full watch face “flashlight” or make my phone ring if I misplaced it. There is also a “Toolbox” with a stopwatch and timer as well as also linking the Flashlight and Find Phone options, both of which I use more than I should need to!Swiping left from the clock face screen goes through the daily exercise screen with estimated steps, estimated distance and estimated calories info. The next left swipe brings you to phone call controls. The next swipes take you to Heart Rate, Sleep, Blood oxygen, music, and weather panels. Heart Rate, and Sleep allow scrolling down for detail windows.The watch arrived nicely packaged. On removing from the box there was a simple protective cover for glass and backside sensor. The watch was completely uncharged when it arrived and took 2-hours to charge to 100%. The watch clearly displays the charge % on the screen during charging if you press the side button. Some watch faces also show your charge % remaining, its up to you what you see based on your choice of watch face design.On turning the watch on, it immediately showed the QR code to scan to download the app. This was very fast. On opening the APP there was a fast process to pair the phone with the watch. Finding a personal watch face in the APP was very simple, I just kept scrolling down until I found what I wanted. I selected it, it synced with the phone in about 30 seconds, and was done. My Dial choices are saved in My Dial in the “Dash Board” on the APP so I can change when I want. I like to switch depending on what I am doing! In addition to time on a watch face with hands, I like to see heart rate, charge remaining, month, day, and day of the week. I found both a simple moon and a cyberpunk watch face that I really like and have the information I want.The watch charging is via a USB-A cable that is about 12 inches long. The phone charging end is via a magnetic connector attached to the back of the watch, so charging requires that the watch be removed. The magnetic binding is strong enough not to disconnect when you casually move the watch around.The Phone calls, texts, notifications (I am on Apple!):All these require that you have Bluetooth on and enabled between the watch and phone/APP.Calling out and answering the phone on the watch are very easy and the audio can remain on the phone or a headset, or it can be swapped to the watch! The watch audio is clear enough. It is quite convenient to look at the watch and see who is calling or has texted without taking the phone out.I can receive my “Messages” texts, though without photos, but can not respond to them on the watch (Android users can).THE APP:On the APP screen at the bottom are Home, Sport, Device and Profile.>DEVICEMost of the settings for the watch are in the APP under Device. Many can also be disabled/enabled on both phone and APP!• Bluetooth Call – sync contacts (choose which to Sync for call ID)? Enable/Disable Calls?• Dash Board - where the watch faces are. Swipe up to load more.• Heart Rate Settings - detect over 24 hours or not? Notify of maximum HR is exceeded?• Blood oxygen settings – Automatic? When to test? How often to test?• Phone – should the watch vibrate with incoming calls? Requires Bluetooth is on.• APP – what apps can interact via Bluetooth…must stay Bluetooth connected.• Sedentary Reminder – should the phone alert you? What intervals? Between What hours?• Alarms – set complex alarm schemes.• Light up – Turn off or on the watch face activating up when you flick your arm.• Do not disturb – Set a time range to disable vibration, screen lighting, and info pushing• More Settings – SMS?, 24-hour clock? Language?• Firmware Update – seamless updates• Reset Device – resets to factory and unpairs, but it quickly pairs and updates to the APP again.• Unpair>PROFILEHeart rate training zones are determined based on age and the calories reported are simply an estimated expenditure based on your age/bodyweight/steps, and steps are estimated based on arm movement, you can go into Profile under Profile and enter key values.>HOMEThe Home screen displays the current days: Steps with Step Goal, Distance and Calories, as well as panels for Heart Rate, Sleep, and Blood oxygen.Clicking Steps, Heart Rate, Sleep, or Blood oxygen panels opens the respective area where you can view different things for each.STEPS, DISTANCE AND ESTIMATED CALORIESEstimated steps, estimated distance and estimated calories are reported, though they are not the most realistic values to focus on for fitness, except for the most sedentary person. This section does have a summary that you can view for any day, week or month. This would allow identifying changes in average steps, distance and calories by scrolling through. There is also Todays data showing all the bouts of walking/running and “Other sources” with your other walking type workouts, but I will talk about this under SPORT.HEART RATERecords and displays heart rate 24/7. Allows reviewing HR history. Each day, a waveform of heart rate recording is plotted throughout the day on both the watch and the APP. Both present daily Minimum and Maximum as well as Average HR (watch shows a weekly average HR) and APP shows % in each Zone of HR Range for day.Currently, even the best sport watch devices have issues with HR measurement accuracy at higher intensity heart rates compared to chest straps. Interestingly, the watch got better as I used it. I am only a little hairy with fine hair, but I tried removing hair in the sensor area to see if this mattered. I think the accuracy at higher intensities is worst at low humidity and improves most when I am sweating/wet! My recent training has had the most accurate recordings, which included when I was training and sometimes followed by being in a sauna, where the watch tracked my heart rate quite accurately for periods over an hour between 60 and 90% HR max. Bravo!!One of the most important metrics on the watch could be Heart Rate as it is an actual readout of activity intensity. The newest studies show that EVERY WEEK accumulating a mix of 150 minutes of FAT BURNING and CARDIO [Moderate] and/or 75 minutes of ANAEROBIC and EXTREME [Vigorous] heart rate zones (as used on the APP!) leads to improved health outcomes, and these are the current WHO and USA CDC guidelines.I compared watch recorded HR values during training and rest to Wahoo Tickr chest strap recordings.SLEEPSleep recording starts itself and was pretty spot on for start and end of sleep as well as being fairly accurate for total and other sleep information. The APP and watch show Averages for Sleep/Deep sleep/Light sleep/Awake/Rapid Eye Movement. SLEEP is an important metric on the watch and the APP allows viewing results for the last sleep day or any recorded day, or averages for any week or month. Since this can be used to roughly gauge sleep quality over time, it is nice that this does have these summaries. This has allowed me to identify changes in my sleep just by scrolling through. Week and month averages show Sleep/Deep sleep/Light sleep as well as early and late to-sleep and waking times!I compared watch recorded sleep to sleep recorded in Sleep Cycle using an iPhone.BLOOD OXYGENRecords and displays in a daily history at whatever intervals you select in the settings and also any spot tests you perform! This is well done. This can be a very important metric for athletes and those with respiratory conditions. Athletes and those who train hard or have a lot of stress can combine sleep and Blood oxygen measures to understand their recovery or state! Further, blood oxygen levels can indicate how much oxygen is reaching muscles during intense exercise. So, looking at sleep values, testing on waking, plus during and after exercise can be informative! Fortunately, the APP and watch allow you to do a SPOT TEST whenever you want! On the watch, you swipe to Blood oxygen or choose it from the menu! In the APP there is a “Start” test button at the bottom of the Blood oxygen screen. In the APP it may ”fail” at first, just repeat it. The watch will start checking and then will vibrate when it is done. Tests get a time stamp. What could be interesting, would be the option to tag a spot readings for Waking, Mid Workout, Post Workout, etc for the APP to include in a plot and comparison over time.>SPORTWhen I swipe R and select TRAINING and then choose a type of workout on the watch from the list, the watch will start to display the duration and HR performance during the training. If I happen to choose a type of training recognized by both watch and APP, it will sync some aspects of the session to the APP, but into the tab for that type of workout and sometimes in “Other sources” in the Steps window if it is a walking/hiking type workout. This need to be simplified into a single workout list by date.If you can find your training in “Other sources” in the Steps window, it will provide steps, cals, duration, miles and then heart rate average, minimum, maximum and charted in workout minutes. Retaining the HR training zones would be more useful for me. Especially since training HR is excluded from the daily total!The syncing of training from watch to APP does not always work. Once I end some of the training types, the record will VANISH. There will be no history under the sport tab and there is nothing in “Other sources” in the Steps window.Other things I have noticed are that the HR recorded during training is EXCLUDED from your ongoing HR recording for the day. Though, any Blood oxygen measures I may have taken, ARE integrated into the list on that window for the day. The workout session and any information are not retained at all in some training modalities that are on the watch but are not in the APP!Currently, this is an under-served section.There are many types of sport to add (via the APP) to the sport list by looking at the “+” at the top, there, select the ones you want to appear in the Watch. REMOVE the ones you don’t want. I found this to be a bit buggy. It would show 3 Yoga and 1 of something I did not select… etc.You can start the exercise in the APP to insure it saves the record, but this is not what I got a sport watch for.Huge thumbs up and I look forward to some adjustments in later software updates.

Buy this watch don’t work

The Truefree GT1 Smartwatch is a solid product for its price. It offers a wide range of functions with a reasonably intuitive user interface. Considering the price, the variety of datapoints is pretty impressive as is the functionality which includes phone calls and simple messaging. You can control music on your phone as well as volume. The vibration is reasonable for notifications, though I do find it to be not enough to wake me up on its own. Battery life is solid. A single charge can last me well over a week, but this is also dependent on how often you pair with your phone for phone calls. Whether or not the battery’s capacity will remain at this level in the long run I can not yet speak on. The watch charges quickly. The screen glass hasn’t shown any signs of damage after a few weeks of not being particularly careful with it, though again I can’t speak yet on how it will hold up in the long run.Anyone looking for an inexpensive Fitbit alternative should be satisfied as long as you’re coming in with tempered expectations (it is significantly cheaper than a Fitbit). You are able to display graphs on both the smartwatch itself and its companion app, which, at least on the iPhone is easy to use but suffers from sluggish (relatively speaking) connection time to the smartwatch when pulling data. Often, you can find yourself waiting 10 seconds for the app to connect and pull data from the watch. Once pulled, the data is presented well, with graphs broken down into bins classifying heart rate and sleep, and you can adjust parameters like measurement frequency for SPO2 (from the default of once every hour to as often as once every 10 minutes.) While the maximum SPO2 measurement frequency does leave a bit to be desired, it’s perfectly sufficient to detect your response to a 20 minute jog. Whether the data is accurate is another question altogether, and is difficult to judge without comparing against gold-standard measurement equipment. That being said, the data seems to be in at least the right ballpark based on measurements while at the doctor’s office and in response to substances like caffeine. O2 Saturation (SPO2) similarly appears to be in the right ballpark. The watch itself is heavier than what you would typically expect from a more expensive smartwatch. For example, the Apple Watch is roughly a third of the weight. The screen’s responsiveness leaves a bit to be desired. In my case I have to touch the virtual buttons a bit off-center to register the correct selection, but it also didn’t take too long for me to get accustomed to this and it soon becomes less noticeable.Everything told, any of the GT1’s shortfalls are easily overlooked when considering it is just a fraction of the price of a more expensive competitor. This smartwatch is absolutely worth the purchase for it’s extremely reasonable price.

I loved it right away surprisingly...however, the 2nd day i had it it froze for half the day. I got it to help me keep track as I exercise and create healthy habits. This is not a good rating so far. I'll try it for 5 more days and see what's really happening here.I was at work when I realized that it had frozen in place for more than an hour. I couldn't access any features. At night when I checked it out it was dead even though I had it charging over night.Since i recharged it from a dead battery from being frozen for hours, now it's working....I wanted to keep track of my steps while at work...so again, we will see. I'll update later...A week later I went out for a run of 30mins, and the watch left me 3 red dots for over a day. I can't trust this electronic over my veins 🤒
