Daniel Condliffe –
Cracking watch. does exactly what i need Steps, heart rate, sleep, calories. very easy and simple to set up and use. very comfy once i put a new strap on it. Digital everything and easy to connect to apps on phone so no worries about it losing track of anything. Battery life is really good. 1 charge a week does it. shame i cant swim with it. Good value for money.

This is a fantastic watch, I wanted an upgrade. It’s perfect and I love the look of it. It charges so quickly and the battery life is extremely high, it connects to my I. Phone easily and I feel it’s great value for money

I loved my watch, I bought a screen protector, and a metal strap at the same time. Worth going for the metal strap, as you don’t get all the gunk that you have with their straps.Within a couple of weeks the silver sensor came off the back, but it was replaced by Fitbit promptly after contacting them. My down side is that just after 2 years old, the battery started to fail. It was saying it was full, but would last 10 minutes, or it would say it’s empty and when you plug it in it’s then saying it’s full. Not long after it went in to rebooting and then total failure. Unfortunately for me, because thinkassemble.co.uk would not show the warranty date starting from the time it was replaced I lost out. Would I buy another, well I just did. Despite it’s issues I loved the watch and it may have saved my life, because it had detected Atrial Fibrillation, which can lead to strokes so because of that my doctors are keeping a close eye on me. Give it a try. I think it’s worth it.

This was bought to replace a Fitbit Sense 1 which had broken. The Sense 1 was always a little finicky. Sometimes it wouldn’t charge, sometimes it’d only charge halfway. The sense 1’s footstep detector was wildly inaccurate. About the only thing it did well was the heartbeat thing, which was quite accurate.The Sense 2 fixes a lot of these issues, and makes for a faster, smoother experience. The Sense 1 would lag occasionally when swiping, but the Sense 2 doesn’t. It’s a better watch all round, I think.We both, originally, paid for the subscription, but it just didn’t seem to give us anything worthwhile. Apps like Zombies Run! give you fun, cool things to do to get fit. Other apps give you recipes, or fitness ideas, or reminders etc… I just feel that the fitbit ecosystem has stagnated a little and they’re just selling smartwatches/fitness trackers without evolving the experience.So, there’s one thing that’s the same with both, and it’s still a disappointment, the app:The thing that annoyed me about the Sense 1 was that it constantly had a “disconnected from phone” icon on the screen, despite the phone sitting RIGHT THERE. What’s the point of having a smart watch that can control the phone, if it only works if the app is loaded and showing on the phone’s screen?I can count on one finger the number of times that I’ve had the Fitbit app loaded, and someone’s tried to call me, and I’ve been able to answer it using the smart watch.The sense 2 does the same. Despite having the App on the phone, it still doesn’t detect the phone unless the app is loaded. And sometimes you’ll load the app, and it’ll take ages for it sync with the watch, despite the watch being in the active bluetooth devices list.I know Bluetooth is a bit flakey, and not all devices are equal when it comes to supporting different profiles, but I would have thought the one thing the watch was supposed to do (exchange information with the app) would have been sorted.The watch was for my wife, and she’s had no problems with it so far. She likes the features, but doesn’t use much of the additional functionality. She occasionally loads the fitbit app to sync the data and see how she’s been doing. but, if I’m honest, I think the App needs a major overhaul. She shouldn’t have to take the watch off, and lie it next to the phone for ten minutes to sync for her to know how many steps she’s taken, or for the most useful information to be buried under a dropdown, which is in a tab, under a graph, which is about four scrolls down. The app has most of what you need, but it could do with a little of a redesign I think… Perhaps find a way to let people configure their dashboard, both in the app, and on the notifications, or widgets on the home screen.

I upgraded to sense 2 from a 7 year old Charge 2 and I have to say I love it. It does everything I personally need from a fitness tracker. Battery life lasts 6 days most of the time but can be less if using your gps. Some of the advanced features with the free trial of Fitbit premium drain the battery. I did have one glitch where the battery drained over night but I removed sp02 tracking and daily readiness, and it then went back to normal at 6 days. The ECG function is good and gps worked well when I tested it on a 9 mile walk. You have to physically turn on gps in the exercise settings which is fine, otherwise it drains the battery a bit. Yes it takes a minute or so to kick in and you can tell once it’s on as the little gps arrow is red whilst kicking in and white once on. Steps are accurate, as are the floor counting. I can take calls on my watch (once I linked it to sense 2 calls on Bluetooth) which is great as you never miss a call if you’ve left your phone in another room etc Obviously you can’t make calls or texts from it as it’s not linked to a phone contract, but I find it useful to be able to take the calls and the sound on it was fine. I personally love the Fitbit app, and the way the calorie tracking and targets work. It is glitchy occasionally but what app isn’t? That really doesn’t faze me as the data is on your watch and always syncs again once the app is fixed as long as you don’t reboot your watch during that time. In 7 years of using Fitbit I have only ever had a handful of issues with the app. The ability to change clock faces is good but it would be nice if there were more that showed battery life as a lot of them don’t. Overall, a good tracker but if you are a massive fitness fanatic who wants a lot more of the advance features some have like fall detection, quicker gps, ability to make calls etc then you may want to opt for another brand of Watch. For me though, the sense 2 is perfect for what I need.

Love it!
Love this activity tracker. Feels more comfortable on a hand to me than other trackers, recognize and tracks automatically workouts a bit better than other trackers. Screen sometimes can lag a little.

love the battery life
It would have been nice if it could also share HRM like the charge 6, otherwise it provides me all the functions i need with a 1x per week charge that was the deciding factor for me vs pixel watch. It would be great if the make a sense 3, however i suspect this is the end of the line for sense products which is a pity.

Uyku takip için ideal.
Öncelikle, bu ürün tam anlamıyla bir akıllı saat değil. Bir fitness takip cihazı diyebiliriz.Uyku takibi için fiyatına göre en doğru verileri veren akıllı saatlerden biri. Veri doğruluğu açısından bir tık üstü Apple Watchların yeni modelleri. Daha iyisi de yok zaten.Ne yazık ki nabız hızlandığında tıbbi cihazlar arasında gözle görülür bir fark mevcut, bu saat normal nabzı gayet iyi ölçse de nabız hızlandığında veriler sapıtmaya başlıyor.Ayrıca adım sayar verileri de gerçekle birebir uyuşmuyor, örneğin sırtınızı kaşımak için elinizi kaldırdığınızda bunu adım olarak sayabiliyor. Oturduğum yerde memleketten gelen fındıkları kırarken 5 bin adım hedefinize ulaştınız diye bildirim gelmesi can sıkıcı, evden bile çıkmamıştım o gün.Koşuya veya yürüyüşe çıktığınızda harita üzerinden gittiğiniz yerleri, hangi yerde ne kadar nabız değişimi olduğunu, oradaki hızınızı vs. gösteriyor. Yüzücü iseniz yüzdüğünüz mesafeyi, havuzun uzunluğunu, kaç tur yüzdüğünüzü gösteriyor.Telefon uygulamasında premium üyelik mevcut maalesef. Ürünle birlikte 6 ay premium hediyesi geliyor, ancak premium bitince aylık 200 TL civarında bir ödeme isteniyor. Bazı verileriniz premium olmadan görünmüyor. Verilerinizi görebilmek için aldığınız bir üründe verilerinizi görmek için bir ödeme duvarına toslamak gerçekten can sıkıcı.Saate neredeyse hiçbir uygulama kurulamıyor, fitbit’in izin verdiği gereksiz iki üç app mevcut. Spotify, youtube music vs. kurulamıyor. Google asistan özelliği bu saatte yok.Eğer kalp ritmi ve adım sayar sizin için geri plandaysa, kaliteli uyku takip verileri için almayı düşünürseniz alabilirsiniz. Bu kadar olumsuz özellik saymama rağmen ürünün şıklığı, uyku takip başarısı (uyku apnesi için takip ediyorum) ve muadillerine nazaran ucuzluğu sebebiyle iade etmedim. Bütçeyi bir tık arttırmak istiyorsanız Samsung Watch 6 önerebilirim, zira Samsung Watch 6 tıpkı bu saat gibi birebir doğru veriler sunamasa da en azından uygulama kurma özelliği mevcut.Umarım gönlünüzce bir saat bulabilirsiniz, iyi alışverişler 🙂
