Great fitness & smart watch.

ArringtonNovember 4, 2025

This watch is great, let me tell you why. It's durable, haven't had any issues with it so far. Been using it everyday for about 4 months now and haven't seen any issues with it. I like the color, but not a huge factor for me. The notifications are great and have a lot of customization options. The band it comes with fits my wrist and leaves no irritation. Set up was interesting, upon turning the watch on, it was initially in Spanish, probably due to the fact description says international version.... But anyway, since I have a Samsung phone it auto dected it after I installed the app and then setup was super simple. The battery life is great, it will usually last me about a week or more. And that's without the always on display and while wearing it bed for sleep tracking. I've found the watch to be fairly accurate as far as heart rate and sleep tracking. I would say it's step counting is probably 50 to 60 steps off when compared to my phone. If it had a built in gps it would probably be just as accurate as my phone. You can reply to texts but only with the pre set reply, which you can customize. You can answer/decline calls, but I find it pointless to use the answering feature unless you have a Bluetooth ear piece. I have notice that if you are in a group text you won't receive notifications from it. I don't know if I missed something in set up, or if it just isn't a thing. All together it's a great budget friendly fitness & smart watch. Read more

The fitbit killer

inayat2012 on youtubeJuly 9, 2025

My wife and I have been fitbit fans since the Charge 2 (2016). Before the google purchase, fitbit was a strong leader in lower cost fitness trackers. It did concern us that our fitbits would die frequently (nearly each one we had died within a year from the Charge 2, 3, 4). However after talking with customer service they would send us replacement. So, ok, we can deal with that. (Even though in the past few years you had to provide a ton of documentation including, IIRC, your drivers license.) I had a fitbit 6 that I got for Christmas 2024. Wow, a color screen. LOL. I needed a replacement as the screen on my Charge 5 kept getting dimmer, and dimmer, to the point when I could not read it outdoors and barely indoors. So I was gifted the Charge 6 and it was big step up. But it took me a few months until I realized that the floors option was gone, not just not working, but removed, to make space for other features I could care less about. So I looked around in late June and discovered the Fit 3. So I bought one. I am SO GLAD I did. What do I need? Step counter, heart rate, floors, distance, calories. Oh, and the kicker for me was AIRPLANE MODE. I study various energetic sciences including BioGeometry and the EMF coming from our devices is not benign. I don't wear a tracker to sleep, don't want anything live, and keep my blue tooth turned off unless I am actively syncing. This is what I see comparing Fit 3 to Fitbit Charge 6. What the Fit 3 has as an advantage: Larger screen, airplane mode, beautiful faces, much cleaner UI on the watch and in the android app(s) (I am using this with a Pixel 7 phone). The ability to sync only turning on bluetooth. A few years ago fitbit/google basically said we aren't syncing your fitbit unless you have both location/GPS and bluetooth turned on. Sometimes you could get the fitbit to sync with location off but this was tricky/spotty. What advantages did the Charge 6 have for me, personally. None really. It cost about 3x the amount for the Charge 6 compared to the Fit 3. That's ridiculous. In a head to head comparsion of measurements this is what I see. Fitbit Charge is often slower to start your step counts and the Fit 3 is quicker on that. So you steps counts are going to go up and perhaps the Fit 3 does count some arm motions as steps when it should not. But the Fit 3 is still very close (within 1-3%) with the Charge 6. The Fit 3 tends to undercount calories compared to the Charge 6, I can't tell which is more accurate. On the Charge 6 bluetooth syncing was always a laborious pain taking sometimes minutes to get the past few days of data and often having to turn bluetooth off/on and/or restarts to get it to sync. The Fit 3 is very fast *most* of the time. I did have one instance where the Fit 3 was not syncing in the Health App and I had to open the Wearable app and trigger a sync from there, which worked. The big thing is battery life. I have automatic activity tracking turned on and except when syncing in the evening I keep it on airplane mode. I charged it overnight last Thursday/Friday before I first put it on. It's now Wednesday evening, nearing 6 complete days of use and my battery level is at 55%. That frugal energy use is really good and is on par with the earlier monochrome fitbits. I am very pleased with my Fit 3 purchase. Back in the early to mid 2000's I was very excited about Timex was doing just in digital watches (Iron Man, etc). The Fit 3 harkens back to those kind of days for me when you could get a very full functionality wrist device that looked good, worked great, and was a good deal. This is definitely worth a close look if you don't need an higher priced fitness/communication device that is emitting EMFs into your pericardium meridian 24x7. Well done. Read more

Such a good watch!

Stephanie KuhlmanNovember 9, 2025

The charge last SO much longer than the round Samsung Galaxy watch and is so much cheaper! It has all the features I wanted like getting texts, showing all the steps, hr, tracking exercise, etc. I wish I would have bought this instead of the more expensive Samsung Galaxy watch. It charges super fast, holds a charge so much longer and is exactly what I need! Read more

Easy setup, great price, decent battery life

ShannonSeptember 2, 2025

Nice little smart watch. Setup was simple enough on my Galaxy S24. It does everything I wanted. Sleep tracking, step count, even blood oxygen levels. The battery will last me, with my current settings of constant heart rate monitoring, about 3-4 days. I've used a few other "fitness" smartwatches and even a Galaxy Active 2 and I'm very happy with this watch. The only issue I have, and the reason for 4 instead of 5 stars is the watch faces are lacking. The ones available are OK but the lack of availability or the ability to upgrade to more, like with other smart watches, is a little unsettling. All in all though, I'm happy with this watch.

Great smartwatch for a great price.

DianeRNovember 25, 2025

Was a long time user of FitBit but soured on that product after newer watches failed quickly. Decided to give this low priced option a chance since I already own a Samsung Galaxy phone. Easy to install app and the features are great! Gives me everything I need to know and lets me customize the face and most importantly, i can actually SEE the watch face again! This was impossible on my old FitBit. Will never go back. Been using for several months with no issues. Impressive! Read more

Didn't know I needed it until I got it.

BrittanyDecember 23, 2025

This has been the most useful and functional purchase I made in a long time. So many benefits. This is what I use it most for: tracking sleep quality, steps, vibration synced to phone alarms, text/email notifications, finding my lost phone in my house (happens more than I'd like to admit), timer (handy to have it on wrist), and water tracker. I have zero complaints and have had it for many months now. I didn't realize how useful this would be (only bought it to track steps) and now cringe when I have to take it off to charge (which is only after 3-4 days). Read more
