Charge 5 Cardio Target still calibrating after 1 month

[RICK603]

I was excited to see the cardio load feature show up, and my Charge 5 has been syncing well, and displays my history of daily cardio load data. Unfortunately, the cardio target still says it is calibrating one month after setting it up. As far as I can tell, both my device and app are running the latest software version. Any suggestions on how to get the target to show up?

Hello @RICK603 

I just saw a Moderator post from 07 Jan 2025 stating that an update to the Fitbit app will start rolling out soon and includes fixes for the Cardio Load & Target Cardio Load general issues. That said, I've seen some users reporting that they got the update earlier this week to version 4.35.

The updates tend to rollout in waves. Keep checking your app store for the update and install it when it's available to you.

If you don't see your Cardio Target Load after installing the app update, please let us know.

App Store is showing v4.34, which I installed. This partially fixed the issue. Now I periodically see popup notices with Cardio Targets, but the main Cardio Load widget still indicates “Today - No Target”. Awaiting access to v4.35…

Hello @RICK603 

My apologies for the typo. The new app version is 4.34, which you've installed.

It might still take a bit of time for your Cardio Target load to begin to show. It's not clear to me if the target algorithm re-starts with the app update or if it will use your current data to calculate your target. If I see any information on this, I'll report back.

Thanks @RiekoC ! I will let this soak for a week to see if it starts working better. I find it weird that I get a pop up that says (today):

“Ready to hit your target today? You’ve been maintaining fitness recently, and your readiness is moderate. Aiming for 6-22 cardio load will keep you on track to maintain your cardio fitness.”

So clearly the app understands my cardio load history, and can calculate a target range for me, but when I scroll down to the cardio widget, it clearly states “Today - No Target”. And once I dismiss that popup message, I cannot get back to anything that tells me today’s target cardio load. 🤷🏼‍:male_sign: All my Cardio Load history is accessible inside the widget, so that is a start…

I’ll be back in a week to let you know if the cardio widget started working properly or not.

Hello @RICK603 

Thank you for your patience & understanding.

It's strange that you are seeing the popup with your Target Load, yet the Cardio Load page doesn't show the recommended Target Cardio Load for the day.

If you're still seeing this problem, please post on this thread in the Charge 6 forum (<-- click link) and tag DavidFitbit, the Moderator, like you've tagged me in your responses. He can forward your info to the engineering team and let them know what issues have not been resolved by the update.

Thanks again @RiekoC !! I do see others in the Charge 6 forum experiencing exactly what I am seeing. Saw one person who said uninstalling and reinstalling the app cleared the issue. Just wanted to confirm that my historical data is stored on Fitbit servers, so in theory I should not loose the historical data when I delete and reinstall the app. I appreciate that odd things can happen, it would just be a shame to lose several years of data, so if loss of data is expected, I might prefer a less disruptive solution or see how I might retain a copy of my historical data locally. I will follow up on the Charge 6 forum after I get your confirmation on how my historical data should behave on an uninstall/reinstall cycle. Thanks for the ongoing assist!

Hi @RICK603 

Deleting & re-installing the Fitbit app on your phone does not delete your data. The way that I understand it is your data is uploaded to your account on the Fitbit servers when the Fitbit syncs with the app. Although there was an issue on the Fitbit side with users seeing their historical data, according to the user reports I've seen, the latest app update to version 4.34 resolved that issue.

I, personally, have delete and re-installed the Fitbit app on my phone without losing my historical data. I've also cleared the storage/data for the Fitbit app on my phone without losing my historical data. The only thing to be aware of when clearing the app's storage/data is that you will need to log back into the app & complete the prompts as if you logging in for the first time. Once I was logged back in, all my data was there.

Please let us know if deleting & re-installing the app worked for you.

@RiekoC Eureka!! Deleting the Fitbit app from my phone, and then reinstalling from the App Store appears to have fully resolved my problem. I’m guessing that there is an issue in the upgrade process that is avoided with an uninstall/reinstall cycle. All my data is still there. As you described, I just had to log back in an everything was great. One step to note: during the uninstall process, I selected the option to retain my Fitbit subscription, rather than deleting that also. Thus, once I reinstalled the app, I could log back in and my subscription and historical data were all still there. Thanks for all the assistance in sorting this out!!

Hi @RICK603 

You're very welcome. It was a pleasure to work with you to get the issue resolve and I'm glad to see that it was successful.

Again, thanks for your patience & understanding.
