PowerWatch 2, Body Heat Powered Fitness Tracker Smart Watch, 200M Dive, GPS, Calorie and Step Count, iPhone/Samsung Compatible

*Update*I just recently switched from a Google Pixel 3 to an iPhone 11 and holy crap...there is a massive difference between the iOS app and the Android app. You can tell Matrix cares more about the iOS app, either that or the Android developer team is lazy as hell. The iOS app is cleaner, it displays sync progress as a percentage, the in app owner’s manual actually works and most importantly, the watch STAYS connected to the phone. With my pixel 3 the watch was CONSTANTLY losing Bluetooth connection, and I would have to power cycle my phone and my watch at least once per day. I know it wasn’t just my phone either because a lot of the reviews were saying the same thing. If you do get this watch, make sure you are using an Apple phone. You’re just going to give yourself a headache using this watch with Android.I've used this watch for about a month, and my overall experience is positive. As a heat harvesting watch, it's calorie burn tracking is very accurate since calories are a measurement of heat. However, the step tracking is difficult to measure because it isn't updated in real time, but I've got the impression that it overestimates your steps throughout the day. I've literally seen it say 50 steps in the morning before I even got out of bed. The heart rate monitor seems pretty accurate, especially during workouts when you can see your heartbeat updated in real time. The GPS is also very accurate, but you can't be moving at all when the watch is searching for your position; you have to stay still until the watch locks onto your position, which takes about a minute. The sleep tracking is hit or miss. Most days the watch would estimate my sleep pretty well but there would be other days where it would tell me I got 23 hours of sleep when I most certainly didn't. I feel like it's a software issue that they can easily fix in a firmware update.As for their claims that you never need to charge the watch, this is only true if you're very active. I'm not the most active person because I usually don't have time for it. If I'm lucky I can get in 1 run per week. The watch lasted me about 3 weeks before I had to charge it. If you're an active person I have no doubt it would last forever.The reason I only give this watch 3 stars is because of its unfortunate tendency to periodically restart itself or just lose connection with my phone. It seems like every 3-4 days the watch will just restart itself for no reason, and after restarting the time and date will automatically be set to a specific date that isn't correct and it won't send any of my phone notifications to the watch. My watch seems to set to June 14th at 6:36pm when this happens. In order to correct the watch, I'll have to do a hard reset on the watch, turn Bluetooth on and off on my phone and kill the powerwatch 2 app before doing another sync. It might just be a hardware issue with my watch but more likely it's a software bug that Matrix needs to correct.

So, you been through a couple of smartwatches and you are curious about PowerWatch 2 and the notation that you do not need to charge the watch because it charges via your body heat and or solar. Well, if all you want is to purchase a self-charging watch and pay the expensive price, that is EXACTLY what you will get! The developers have not figured out how to KEEP the watch linked/synced to the Bluetooth feature with your phone. So, when you get this watch, you download the app, create your account, start the watch via the instructions included and you pair the watch to the app. All your problems begin following that act. The purpose of the smartwatch and its trackers is to collect the data and make the data available in the app to track your progress. BUT your watch will lose its Bluetooth connection to the app and it will not automatically sync once you lose the connection. In my experience, it happens two to three days after you pair. Your next effort is to review the instructions for reconnecting your watch to the app and you are surprised to learn that the instructions do not indicate how to re-connect due to a lost Bluetooth connection. Your choices are first set-up and factory reset. You try turning off then on the Bluetooth on our phone hoping that your watch re-connects, and you learn that it won’t. You have been using the watch to track your activity and you don’t want to lose that data, so you contact the PowerWatch 2 support team (via email only option) inquiring for assistance. The email you receive dictates that you unpair the watch from the phone, uninstall the app and get into the watch Settings to factory reset your watch. Then you cycle through re-installing and pairing the watch. A few days later the watch has lost its connection again and you once again cannot reconnect the watch to the app. Your phone’s Bluetooth indicates that the phone is paired, but that app indicates that the watch is not connected. So, you are back at uninstalling, factory resetting, and re-pairing. You will have to do this several times in a month because the watch loses its connection in a relatively short amount of time. When you must update to a new firmware version, your watch will also not be connected to the app and you must uninstall it all again and cycle through the same processes to reconnect. What this means is your watch is not successfully and frequently updating your activity data to the app and the trackers, therefore no data is communicated from the watch to the app for you to see or compare. Which means you are not tracking anything. So, if you want to spend a lot of money on a body heat/solar generating watch, with poor Bluetooth connectivity and lack of tracking any or all your activities, this is the one. If you want a smartwatch and or fitness tracking watch that successfully monitors and successfully transfers the data, it collects to the app PURCHASE A WATCH FROM A DIFFERENT MANUFACTURE. My Marshall speaker’s Bluetooth connection is more reliable than this watch and the speaker is not that SMART. I purchased this watch in February 2020 and I am ready to get rid of it because it will not keep its Bluetooth connection which defeats the purpose of tracking my activity and the data the watch collects NEVER transfers to the app BECAUSE I AM ALWAYS HAVING TO FACTORY RESET the watch to reestablish a Bluetooth connection. I have updated the firmware a couple of times and PowerWatch indicates in its update "improved Bluetooth connectivity" but I still experience the same problem, loss of connection, and inability to connect sync/transfer data from the watch to the app. My recommendation, purchase from another manufacture because you will waste $499 for a watch that does not do what it proclaims to do. It will self-charge and show the time, but you’ll be hard-pressed to get your data into the app for your review.

As a wearer of Rolex for a good part of my life, I wanted to upgrade to a smartwatch. I wanted a watch that I could wear with my formal clothes and also my sporting attire. (I go for long walks and I am health nut). I had been looking at a lot of Smartwatches and most of them either look bland or futuristic none of them looked smart enough that would cover the above needs. Further, all of them had me tied to my electrical socket. For me, the phone was about as far as I am prepared to go.Then someone told me about this company called Matrix and their watch that never needs charging. He told me that it is charged by you. I thought this was ideal for my needs as described above. I must say I was not sold that it could do what it says it would. When I saw the picture of the watch, I liked the look, it for sure fit the look I needed and if indeed it would fit my Untethered need from the socket I was in as they say Hog heaven. So, I decided to buy it.I have been wearing this watch 24/7 and it is really beating all my expectations. It looks great on, I can go in the shower with it, I can swim with it. I go on my walks. I live in the country and I can walk feeling the safety that I have my GPS and I can walk at night under the stars and I have my watch.I love this watch and its sort of part of me. My Rolex has been moved to the safety box in the bank. If there is one this that I would say that I would like is a few more seconds on the night light. Otherwise, I am a convert to Matrix. I don’t put many reviews online this one I was compelled to do since I really love the product.Silincowala

It's a good concept but it's badly let down by buggy software, both on the watch and the companion app.I've had mine less than a week and had to reset it several times as data wasn't syncing to my phone.It loses connection to my phone when my phone is less than a metre away.Reviews online and even the dedicated Facebook group are littered with complaints.It obviously thinks I'm dead (no heartbeat) and I can go days without sleeping according to this watch.I'm hopeful the next firmware update might improve it, but as this is their third stab at making a watch I'm not hopeful.

Didn't work from new. Returned with 48 hours. Great idea, pathetically poor quality

Cuando pagas casi 500€ por un reloj, esperas algo de calidad y cuanto menos algo que funcione,Pues ni la calidad, plástico malo, silicona mala..... ni funciona, lo emparejé tras 20 intentos, errores en la actualización de firmware continuos, a veces medía el ritmo cardiaco y a veces no y no logré que cogiese en ningún momento señal GPS.Por suerte he podido devolverlo

Leider ein unausgereiftes Produkt.Sync mit Google Fit funktionierte anfangs überhaupt nicht, durch ein Firmware Upgrade jetzt hin und wieder mal, dafür funktioniert nun die Taste zum Nachrichten abrufen nicht mehr.Das einzige was tatsächlich zuverlässig funktioniert ist die Selbstladefunktion.Und das Schlaftracking hat neulich behauptet, dass ich 34 Stunden an einem Tag geschlafen habe, die Hälfte davon eher unruhig...

Ja, es gibt vor allem aufgrund des Preises eigentlich keinen vernünftigen Grund sich eine Powerwatch zu kaufen. Doch wer einen Fitness- Tracker sucht, der nie geladen werden muss, ist hier genau richtig. Aufgeladen wird die Smart Watch durch Körperwärme und Licht. Die Powerwatch unterstützt u.a. GPS - das dank AGPS sehr schnell die Position bestimmt- und Messen der Herzfrequenz. Die Temperatur wird auch gemessen. Normale Uhrfunktionen wie Stoppuhr und Alarme werden auch unterstützt. Mithilfe der APP kann sehr exakt eingestellt werden, welche APPs Notifications an die Uhr senden dürfen. Ja, man muss Technik begeistert sein, um sich so ein Produkt zu kaufen. Zur Sicherheit wird ein Ladegerät mitgeliefert. Dies habe ich nur am Anfang genutzt um die Smart Watch ein Mal voll zu laden. Jetzt benutze ich die Smart Watch seit einer Woche und der Akku ist noch immer voll :) . Der Support antwortet bei Fragen innerhalb von 24h; ich habe es mehrfach getestet. Da können sich andere eine Scheibe abschneiden.Alles im allen ein tolles Produkt.
