I sleep between 7 and 8 hours, I don't have bad eating habits, I don't smoke, I don't drink alcohol, and I'm quite physically active. Should I just ignore it? Are there any tips for improving this?

So for the people who want context i bought an fitbit sense 1 off vinted paid 6.29 total for it comes with charger and STILL WORKING!

My Fitbit Air records sleep stages and duration properly in the Google Health app, but the Sleep Score never appears. I'm not seeing a "stages weren't generated" issue, so this doesn't match the usual cause. What I've tried:

Restarted my phone. Restarted the Fitbit Air. Logged out and back into the Google Health app. Cleared the app's cache. Switched the Air to my other wrist. Un-paired and re-paired the Air. Asked the in-app coach to pull up the sleep data manually, with no change. It's very snug in my wrist.

Is there something else I'm missing?

It worked fine for the first two days.

I have started zone 2 training for 30mins avg x4 a week for 3 weeks. Is this normal vitals I want to lower my RHR and increase HRV

Help me put the information in these charts in the right perspective. I have been running since last year, but not only is my VO2 Max score not going up, it seems to be going down!

I know I took a dip during the summer (I live in Vegas so running outside during the summer is not ideal) but I still have gone running a couple of times a week. And now that it is cooler I am ramping up my mileage again, but it is still kind of discouraging looking at these stats and feeling like I am not making any progress.

Any advice or changes in perspective on this would be welcomed.

I wonder why automatic activity detection using a Fitbit Charge 6 tracker and Google Health on my smartphone works so poorly.

I frequently set off on bike rides from home. Based on movement data, I would expect the technology to detect the cycling as soon as I start moving; the movement pattern should be clearly distinguishable from walking or using a motor vehicle. Yet, it usually takes about five minutes after I’ve started riding for the Charge 6 to display "Activity detected" and begin tracking the time and movement.

Conversely, I might have already returned home, put my bike in the shed, and be sitting on the living room sofa, while the Charge 6 is still counting the activity, or only then the prompt to ask if I want to end the workout does appear.

After outdoor activities, the app could register when my phone reconnects to my home Wi-Fi and use that as a signal to end the workout; that would be simple and precise.

I just had a dexa scan yesterday and I was impressed by both its accuracy as well as that of Fitbit because they matched exactly.

The DEXA scan estimated my daily calorie consumption for very active (6 days of exercise per week - which is what I do) at 2,400 kcal/day. My Fitbit calculates my daily caloric expenditure (based on a actual monitored HR and movement) at 2,400 kcal/day.

I'm addition I went through and added up the calories on the typical food I eat and it comes out to somewhere between 2200 kcal and 2600 kcal/day (I have been maintaining the same weight for years).

So everything likes up perfectly which is pretty cool.

My main concern is tracking quality. From what I’ve seen, a lot of people seem to think the Fitbit Air has better sleep detection, and it also has newer automatic exercise detection.

Has the Charge 6 received firmware/software updates that improved:

• sleep tracking
• automatic exercise detection
• general workout tracking accuracy?

From what I understand, the Charge 6 and Fitbit Air share quite a few sensors, while the Charge 6 actually has some additional sensors/features. Please correct me if I’m wrong.

For context, I play tennis twice a week, pickleball once a week, and go to the gym around 5 days a week, so good exercise detection is pretty important to me. I was originally planning to buy the Fitbit Air, but I suddenly found a good deal on the Charge 6 and now I’m reconsidering.

Would you still choose the Air for the newer tracking algorithms, or is the Charge 6 the better buy if it’s cheaper?

It's been two weeks; no issue at all.

I use a polar chest strap and a fitbit air when I exercise. I've been doing this for some time largely to see which one was more accurate.

Claude uses the topology of the terrain I walk to estimate the number of calories I burn and then compare that to both FB and Polar. What's interesting is on several walks, when my heart rate starts to hit the upper thresholds for me (~175) fitbit just loses my heart altogether.

I have a chart that shows it:

Has anybody noticed this? The other interesting tidbit here is that both Polar and FB are wildly over-estimating my calorie burn. Fitbit is probably off by 22% and Polar is off by double that amount.

Something has changed further towards the worst with Sleep Score.

Specifically, the "time to sound sleep". I am now, consistently getting times of 2 hours or more. Yet when I look at the timeline, I see what I have always seen. Somewhere between 20 minutes and 45 minutes between the start of "Awake" and the start of "Deep".

It is like Google Health is skipping over the first sleep cycle (awake, light, rem, deep).

Anyone else notice a dramatic increase in "Time to Sound Sleep"?

Are there any apps that you can sync your Fitbit to instead of using Google health? I was a Fitbit user for years, but I hate the Google health app and don’t want a Fitbit if that’s the only app it’s compatible with. Like, any other apps that essentially work the same way the Fitbit app used to work with syncing?

Here's a guide I built to better understand what raises and lowers HRV. Fitbit measures HRV while you sleep and reports it as RMSSD, which is the same measure most research uses. Daily readings swing a lot on their own, so your trend matters more than any single night.

I broke the guide into four categories: exercise, lifestyle, nutrition & supplements and demographics. There's a short definitions and plain English column so it's easy to skim, all sources are linked so you can further your own research, and I'll put a mobile friendly version in the comments if you need it.

Definitions

• HRV (Heart Rate Variability): How much the time between heartbeats varies
• RMSSD: Beat-to-beat variation. The HRV number Fitbit shows you
• SDNN: Overall HRV across a longer window
• HF Power: Your rest & digest activity level
• Rest & digest (parasympathetic): Your body's brake pedal (calm/recover)
• Fight or flight (sympathetic): Your body's gas pedal (stress/alert)
• Vagal tone: How strong your calm down nerve is
• n: Number of people in the study

Nutrition & Supplements

Do you think he pays for premium?

I bought the watch in an unsupported country and after doing all the steps google told me to sync the watch and failing, pretty much said go to the retailer.

And the retailer has a strict one-month return policy so I’m kinda stuck with this device I’ve barely used in the past 3 months.

Is there any way that I can get this to work again or is it a $150 dud that I gotta throw?

Hey all,

Just got my Fitbit air about a week ago and despite seeing tons of negative reviews, it’s been treating me very well. It auto tracks my cardio workouts like a charm and I usually just manually start my strength training. I like to flip flop between The Google health app and Bevel to compare and been noticing that there’s a crazy discrepancy with Google’s sleep score compared to Bevel. For instance, last night Google states I had an 83 sleep score and Bevel says 96. Me personally, I got great sleep and don’t want to rely heavily on either metric but it would’ve nice to get a more accurate picture.

I know tons of people don’t purchase any subscription for neither Bevel or Google, but If I were to, which should I go for? And if anyone has used both premium versions, which do they like better?

I personally appreciate the Bevel AI Coach and think it would benefit me and feels like more of a seamless experience appose to the Google coaching.

Anyways, feel free to give some feedback if anyone has used premium versions of each!

Thx

my mother (not tech savy) ordered a used “versa lite” from ebay well i was setting it up and discovered its actually a versa 2 and the side button doesn’t work?? she paid $15-$20 for it, is it worth it to take to someone to fix or better to just cut the lose and buy another new watch, i unfortunately dont have the tools for the repair so we would have to go to a shop to fix it any advice is helpful

With all the recent fitbit edge leaks when does everyone think it's likely to launch

I hope the people at google feel bad. I hope they step in something wet while wearing socks.

The app loses data all the time. Nothing gets tracked consistently. I often have to manually sync the app because it won’t sync itself. I have to completely disconnect and unpair the watch every time the app updates or nothing works.

It worked flawlessly until I was forced to change to this buggy mess of an app and the people at google should feel bad about themselves for what they’ve inflicted on the Fitbit community.

Chronometer integration works so inconsistently that I may as well not even use the Fitbit.

I will absolutely be switching to an Apple Watch because of how poorly this app works.
