The Nautilus Activity Fitness Tracker Smart Bracelet, Smart Watch with Blood Pressure Monitor, Heart Rate Monitor, Pedometer or Step Counter, Blood Oxygen Monitor, Sleep Monitor, 50 Meter Waterproof

I'm really enjoying the The Nautilus Activity Fitness Tracker! My main purpose for buying this watch was to be able to have a record of how many miles I run each time I workout and to then eventually challenge myself to beat that record and further my distance. I only started a short run the other day but already, I find it so easy to use! Once you download the free application onto a smart phone that works with the watch, you'll be able to have a log of everything that you accomplished. There are various activities such as running, swimming, biking and a few more and this watch will even tell you how many calories you've burned!There are many other very cool features such as this watch can read your heart beat, blood pressure and blood oxygen!There was a bonus to this watch that I just love and that is having a record of your sleep pattern, showing you exactly how much light to even deep sleep you have and I was so surprised to find that I only was having 2 & 1/2 hours of deep sleep!If you want to make changes to your health or just improve on your fitness goals, then I strongly believe this activity fitness tracker is the way to go to fulfilling your goals!My watch came within a week as expected and was packaged properly to protect it! I'm very happy and so grateful to have found this wonderful watch!

I have had this now for a couple of weeks (my 3rd tracker in 5 years). I'm liking the watch for the most part but the Fitness App for the phone is crap. Sometimes it registers readings. Sometimes only HALF of the readings. Sometimes nothing for days. Sometimes it registers readings while sitting on the dresser for 3 days (surprised me that I had heart rate and blood pressure readings when I wasn't wearing it!) I don't use the message or weather. I'm not confident in the accuracy of the heart rate or blood pressure readings as they continually run much lower than what I get for readings taking them myself. But for steps and distance, it seems to be pretty accurate. Battery is better than most -- last about a week before needing to be recharged.

Unfortunately this didn't work for me. I got the app and set everything up. The watch was synced and it appeared to be working. No matter what I tried it would not take any readings on me. It worked perfectly well on my husband. I'm not sure if it's because my wrist was too small or perhaps my readings were too low, but it simply won't work for me. It looks nice and the display is clear though.

I like the bigger display and it is visible outside in the daylight. The app that works with this watch lacks a link to the O2 sensor feature of the watch but that isn't a big issue. I am a little disappointed that the heart rate monitor doesn't have a setting for checking the heart rate every 10 minutes like my first fitness tracker. The shortest interval that can be set in the phone app one hour apart. The phone app, Flagfit 2.0, could use some improvement but I was able to figure out how to access it and use it's features & settings.

Works as good as any expensive one would. Keeps everything I need to know and waterproof it is. I love to swim and this smart watch is fantastic. Since I have stage 3 CHF it keeps me knowing just how much my oxygen levels are. It let's me know to slow down and get my oxygen levels up.

It came Really Fast And Was Packaged Really Well!! I Know My Husband Will ♡LOVE♡ It For Father's Day!!:-)

Nice watch with a lot of features. This watch is being used by my dad to keep an eye on his vital signs.
