Scanwatch - Smart Watch & Activity Tracker: Heart Monitor, Sleep Tracker, Smart Notifications, Step Counter, Waterproof with 30-Day Battery Life, Android & Apple Compatible, GPS, HSA/FSA

This is my third intelligent watch. I started with a 2nd Gen iWatch and used that for a few years. Last year I decided it needed updating, and driven by cost I purchased a new watch from another manufacturer. I liked that it operated between charges for 12 days, was lightweight, had a very clear display and could monitor my sleep habits as well. Then I discovered the hybrid watch, and after careful research bought this one.LIKES:1) I was after a constant-on display, at least to show time. My previous watches only displayed in response to certain arm movements, and often ignored my attempts to display time, without having to push a button, which required both arms. My last watch could be set for a constant-on display, but only at the cost of battery consumption and more frequent charging. This watch simply solves that problem. I am writing this after wearing and using the watch for about a month. It is only on it’s second charge cycle.2) 24 days between charging, that is an excellent power management scheme built-in.3) ECG and SP02 measurements in addition to heart rate, distance and steps.4) Simple and easy-to-read display of your status, a single knob/button to access any feature the watch has. And the hands move out of the way if they are obscuring the screen, they are separately motored.5) I’m after functionality, not flash, and this fits the bill perfectly.6) Phone app seems pretty reliable and updates data the watch has collected.7) Simply nice looking and comfortable on the wrist.8) Easy to read single-hand lower dial shows your percentage of steps taken. Now this could be a second display, or repurposed possibly.DISLIKES:9) The watch collects sleep data, but it only is displayed on the phone app. The watch itself should include the previous nights sleep score.10) No indication on the watch of the charge remaining in the battery. Most lithium batteries prefer to be recharged when the remaining charge drops to ~20%. This watch does inform you when the remaining charge drops below 10%, but that is going further than I would choose. The single-hand lower dial could be usefully re-purposed to display remaining charge which is an option I would use.11) The display, albeit small, does not have a feature where you can have it black-out at night. My previous watch had an option to set a go-dark period (say 10pm to 6am). I have noticed this display illuminate while I am moving around in bed. It is distracting if I am dozing.12) The Bluetooth does not seem to have the range my previous watches had. If I’m close to my phone any texts coming in will scroll across the screen of the watch. Many times, I just see a Text icon (…) but no text. And often it will not even notify me of a text, possibly because it is out of range. I do not lug my phone around with me in the house, which was not a problem before I got this watch.13) The watch is heavier than my previous, probably similar in weight to my old iWatch.14) The watch repeatedly tells me how far I cycled. I don’t cycle. I don't have a bike. You cannot turn off that ‘feature’, even though you can deselect cycling as part of your exercise regime.15) To use the ECG and SP02 features you have to put your other hand over the watch top bezel, and hold it there for 30 seconds. The SP02 readings have been concerning. It has offered by 02 levels being at 89% or 93%, but when immediately re-taking them, it reports 98% or 99%, so I’m not sure I can trust it.16) The sleep monitor function has accused me of getting up at 4am (not going to happen!) and consequently given me a very low sleep score.17) On the App, it depicts your sleep state from going to bed to getting up in a bar graph form. The included key to the bar graph is wrong. It has reversed the bar colors for light sleep and deep sleep.18) I can find no stand for the watch charger.19) There seems to be no indication of when the watch is fully recharged, although it seems to take less than three hours.Overall, this watch is pretty well thought out. Sure, I have some criticisms, but it is better than the iWatch I was using and I can always see the time single-handed.UPDATE 6 months later. I still like this watch. It had endured some harsh use and looks like new. A couple of negatives:1) The blood oxygen measurement is not reliable. I will try it, which takes 30 seconds of measurement. It comes back as ’measurement failed’. I immediately try it again. 93%. I immediately try it again. 98%. Blood oxygen levels don’t change that fast. Only the ability to read them can.2) The pedometer counts steps, except it consistently undercounts by about 30%. I first noticed this when family and I walked the Las Vegas strip. My family had iwatches fitbits etc. Even though we had walked as a group my step count was 30-40% less than theirs. Theirs were consistent between different products. Mine was always low. I used a belt mounted pedometer and a second Watch product on my other arm for a day. I swapped which watch was on which arm for a second day. The Withings watch always counted ~30% lower. Not a big deal, but could be better.3). The watch lasts days between charges, which is great. But it does not have any indication of the state of the battery until it is below 10%. You can drill down menus on the phone app to find it, but that is not convenient. On its own, that’s ok, except it has a second feature that trips on this. If I glance at my watch, I can see the time based on the hands of course. If I lift my wrist to see the time the digital display lights up as well, depicting the time and date. If I lift my wrist and press the crown I can select readings on the digital display, and cleverly, if either of the two hands are obscuring the display they motor over to 10 and 2 so they are no longer obstructing it. Nice feature. Except if you lift your wrist to see the time when the battery needs recharging, the hands motor to 10 and 2 so the display is unobstructed to inform you it needs recharging. So I glance at my watch, and can no longer deduce the time with the hands. Ok, you say, no big deal. But it has annoyed me more times than I would have anticipated.3) if I get a text on my phone, one of three things happen. Nothing. A message (…) symbol appears on the display. And often, the actual message scrolls across the display. Which is great, except not so much. If you are using your hands when a message arrives, and can’t immediately read the message as it is scrolling through, there is no feature I have found that recalls it on the watch. So you miss the first part of the message , you have to go find your phone to see who sent you something, and what it was. I find this quite distracting.It is still my favorite watch, but there is room for improvement. Lastly, I wish it would display my sleep score. Why I have to open the app on my phone to see that is beyond my understanding.UPDATE: The Settings screen in the watch now shows state of battery charge. Now maybe it’s been there a while but I’m pretty sure it wasn’t when I purchased the product. That is a nice enhancement.It has other watch settings under ‘Settings’ but I haven’t yet resolved them.

Super big selling points: 1) long battery life, 2) very scratch resistant glass, 3) "normal" looking watch that can track basic info about sleep and steps and heartbeat, 4) can measure ECG, 5) heartbeat measurements are consistent with what a standard pulsoximeter measuresThings I do not like: 1) timer is not great, after 20 min one can choose times only with 5 min increments, and the max time is 2 h. 2) when i take off the watch in the evening before sleep for a short time and then put them for sleep, it thinks i was sleeping while it was just taken off, but at least i can edit this later in the appThings Im neutral about: 1) heartbeat and SpO2 are not measured in real time but rather once every 30 min or so. There is an option in "workout" to measure those non-stop.2) SpO2 measures well only if you wrap the watch reasonably tight around the wrist. But if you do wear watch reasonably tight, the skin on that area eventually starts coming off (a little bit). I believe this is a general problem with all the smartwatch.Overall, I think the price of the watch is a bit too high for a relatively linited functionality (it does not measure the body temperature and the sleep info is also pretty basic, it does not distinguish REM from deep sleep, etc). I got "used" option which came in very good condition so I'm glad I did not pay the full price for it.If you have an Android phone and want more details about your sleep and health, get other watch.

I really love this watch. I say "watch" because most of the features of the fitness tracker aren't that accurate. Let me 'splain.TLDR; It's beautiful, the O2 sensor and heart rate monitor seem pretty accurate, but the steps are off. Readability is much improved over the previous model, but still not that easy. The ECG function is pretty cool, but not something you use very often if you are healthy and of course, I have only their word that it really works. It doesn't really detect activity and since I usually forget to start it on a work out, all I get are increased steps. The crystal is very durable and scratch resistant. IP68 Waterproof!Long Story:My wife and I are "required" to wear a fitness tracker for insurance purposes, because it's a free country and all. Anyway, they did provide us with something they called a fitness tracker and I called future ocean pollution. All it did was track steps. Every other feature was merely derived from that. I put that on my wrist and walked 10 paces. It registered 11. I also put on my friend's uber-expensive Apple watch tracker thing and it registered 0 steps. I used an app on my phone which registered a massive 40 steps. I also put on a regular old pedometer and it registered 10 paces. So from this, I concluded that the pedometer was the best at tracking steps. I should note that 10 steps is not a very big sample and over time switching off various trackers and wearing them simultaneously I found that none of them are really that accurate, so you really need to adjust your thinking on this matter. Face it, they are measuring arm swings and vibrations to determine how many steps you've taken. Holding a Starbucks in your hand has GOT to affect that somehow.Because I hated that stupid crappy freebie I was given, I bought the previous model of this Withings which I thought had a beautiful design. But it had some flaws. The tick marks for the numbers were so faint and the hands were so difficult to see, determining the time was nearly impossible. Pressing the button displays the time, but that was pretty much impossible to read outside. There were few features and the steps were about 30% high (going by the feeling I have after so many tests with steps over the years).This new one has fixed many of those problems. It is a little larger, which is kind of a bummer for me, since I apparently tend to round corners too sharp and smack it on everything. That said, it is still much lower profile than most men's watches and I think the larger diameter makes it easier to read. On that note, they improved the visibility of the tick marks massively as well as the hands and so now you can actually read the time. Pressing the button displays the time in the tiny attractive circular window at the top, but it is still very difficult to read outdoors. The heart rate monitor and the O2 levels were very close to the medical finger tip reader we have at home. So kudos there. The steps however, report quite a bit low. For instance, I play disc golf twice a week and sometimes I'm out there for 4 hours. On a long day like that I know I should be in the neighborhood of 12,000 to 15,000 steps and the Withings will only report my goal of 7000 steps after I've arrived home sometime later in the day. No flippin way! For me this is not a problem, because I use these tools on a relative basis. Disc Golf is 6000. Today I got 3000 so I'm about 2 hours of golf. Not a bad day. But for the insurance company though, you probably want to get that app that over reports by a factor of 4, because the more the better, right?The app is ok. It has some of the same annoyances that others do. Nothing is going to be perfect. Anyway, I could go on all day and still not cover everything, so bottom line; If you are willing to admit that NO fitness tracker is going to be too accurate, then I think this is the best because even if it weren't a fitness tracker at all, it's still a beautiful watch. More like a watch +. Think of it that way and it's totally worth it. I love mine but can't in good conscience give it the full 5 stars.

El sentimiento de no tener que cargar todos lo días es muy raro y bien recibido.Tiene las mismas características que uno smartwatch de última generación (ECG, sleep track, saturación de oxígeno) pero sin ser invasivo y de forma minimalista, lo que te ayuda a desconectarte un poco de la cadena que se ha vuelto un smartphone y una el diseño (pasa por completo desapercibido por Smart) es muy casual para combinar fácilmente con cualquier estilo.En los contras a veces tiene problemas con las notificaciones, pero he escuchado que ha mejorado bastante y no dudo que siga mejorando. Las manecillas en un par d ocasiones se dejaron de sincronizar, pero consultando la app del reloj se arregló en automatico sin problema. No veo el razón para no confiar que todos estos detalles se arreglaran en updates de firmware.¡Muy recomendable!

Me gusto muchoo

Like the looks and the functionality, battery life is much shorter if you enable all the features, i got 4-5 days but if you minimise these it’s much longer which kind of seems strange to me, never expected 30 days but to have to turn stuff off to get reasonable life seems to defeat the purpose of a hybrid.

This is a very nice watch, very stylish, made with quality materials and nice features. What is a deal breaker for me is the inaccuracy of the heart rate sensor. I tried fitting it in my arm in all positions and at first the results would be correct, but at the end of the day I would see swings into the 30s bpm, which is obviously wrong, unless I entered into a Tibetan monk trance for a minute and I didn't notice and also swings into the 160bpm even if I spend the day working from home... I know my colleagues are a bit exasperating, but I don't think that is enough to put me into this marathon-like heart regime.I understand that all this optical HR sensors cannot be perfectly accurate, but withings should be able to do some noise cleaning of all those curves. There are so many ways to detect outliers that I'm a bit disappointed they have not even thought about it. I hope withings will do something about this in a coming software update... I will return the watch anyways and I may think about getting one again in the future if the forums show positive feedback about the updates.

Awesome Time Piece! Very Snazzy!Great look to it. Always get comments. Has an awesome fireworks star message when you reach your step goals n buzzes! So purdy! Very easy to use. Anti scratch is a life saver. Banged on so many things.. I work with animals... say no more... not a scratch or dent on it. Rock solid! Sooo good! Finally. A watch that lasts more than just a few days at work! Works a ok apart from you gotta keep it charged otherwise the time is incorrect and sometimes wont connect easily to my phone. But all normal issues. Overall, top knotch! Thanks!
