## Questions & Answers

**Q: I need to know if this product measures spo2 levels? that's the only reason i'm looking for a new device.**
A: The Fitbit Sense measures Sp02 at night which is vital for my health. Also the alerts when your heartrate goes above or below certain numbers iis awesome. BEWARE: If you change the band to a designer band (I got the Pendleton Weave), it changes the fit, stopped giving me a sleep quality score, stopped measuring my Sp02 @ night. And I started earning 8X the floors I normally get. Lol Not so bad but I knew I didn’t earn the # of floors. Even though this question is 4 mos old, hopefully it will help someone else when choosing a band. The band that comes with the Sense isn’t very flexible. It rubbed a very sore place on my wrist bone.  I had a Charge 3. Chose a Sense after 3 pneumonias; one causing congestive heart failure and because I have 
SVTs. There are nice features to help me monitor these things & share with my physicians.

**Q: Does it regiater 02 sats?**
A: Yes... It measures SP02, but only at night while sleeping. That is when its important; when the heart is at rest. The Sense does measure the resting heart level. During the day, there is a relationship between breath rate and heart rate. The body calls for more 02 so the heart pumps faster for faster passage of blood through the lungs. You can see this relationship at HEART RATE. At the top there is a heavy white graph of the average resting rate. Swipe LEFT and you will get your cardio score. I have breathing issues sleeping and the Sense has helped me greatly.

**Q: Is there a way to calibrate the heart beat? it is really inaccurate as measured by my charge 2, polar, kardia , anybody?**
A: There is a whole thread on the Fitbit Community board with multiple users saying  how inaccurate the Sense is when measured by accurate heart monitors like the Polar chest strap and that the Sense is only accurate when you are inactive. So if you are just sedentary you are ok. But I've found that it is not as accurate as even the Charge 2.  So idk if it can be synced- I don't think so.

**Q: If i buy this on amazon will the watch only come with alexa support or will it also have the google assistant support as well?**
A: At the moment only Alexa is enabled on the watch. Next month there will be an update that enables Google, the ECG and probably SPO2 sensing without a specific watchface. Trust me - Fitbit is about to be owned by Google... Google Assistant will be at least offered on it regardless where you bought it. It's just they need to update the firmware to support it.
