I’ve had the Ultra for a while and was curious to compare it to the Ultra BodyScan. I took a reading with the BodyScan, then with the Ultra. When I looked at the app for the BodyScan it had the same format as the Ultra and even the slightly different weight as the Ultra just recorded. It looked like the Ultra overwrote the Bodyscan.
So I deleted the BodyScan and re-added it. I repeated the measurement on both, then looked at the app. This time the BodyScan had the full report, but the Ultra had the identical format and info as the BodyScan. So this time it looks like the BodyScan is overwriting the Ultra.
So it looks like I’m stuck with one or the other and can’t compare them,
Edit: After waiting a few minutes, I checked the Ultra in the app again. It had updated with the correct info for the Ultra, however, the BodyScan now looks like the Ultra. So I’m guessing that the last one to update will update both devices in the app with it’s format.
I don’t use either of these but have Scale S, and my expectation with having two different scales on the same account is that all of the measurements would be added to the account chronologically. With Scale S, I can check the History screen to see data for every time I’ve stepped on the scale. If your Scale Ultra and Scale Ultra BodyScan are updating your user profile correctly, then I would expect to see measurements from both in the History, but I didn’t see in your description if you checked that.
Since I don’t have those models, I don’t know if you have that feature (I would expect to see it) and don’t know where it would be in the UI, but that’s something I’d poke into, because I imagine you’re recording data from both and not seeing anything overwritten. I imagine the app is just showing you the most recent reading for you (regardless of which scale was used) whenever you open one of those modules within the app.
Did the app keep all of the data from the ultra? Meaning, can you use your body scan going forward, but look back in history and see all of your data from original ultra readings and new body scan readings? Or does the body scan data overwrite the historical data and can no longer be viewed?
First, let me say I have the Ultra and the BodyScan as separate devices in the Wyze app.
If I use the BodyScan, it will show me the detailed report and segment analysis in both devices, changing the UI for the ultra device. If I then use the Ultra, both devices will have the Ultra UI, meaning the report and segment analysis of the BodyScan is gone.
In both cases there is still the History graphs, but it’s annoying that both devices will have their UI sync to whatever was used last. There was no point in adding the BodyScan as a device to the app.
Correct. I upgraded from the original scale to the scale.X and then to the ultra and now to the body scan model and every time I upgraded it preserved all of my data from the previous models and I can open the icon for any of the scales in the app and it will show me all the data from all of the scales because it is stored in a central scale database that they all use the same way. So you can take a measurement from one scale, then another scale model than a different scale model and they will all update the same history location, and you can view most of the same data by looking at any of them in the app… Unless that model doesn’t have a particular measurement then it won’t show it of course, such as if I open measurements in the scale X or the ultra or the original scale, then I’m definitely not going to see the detailed body scan measurements for my arms and legs, etc. but it will show me the weight and fat measurements and most of the others that all of them support. Each scale model’s UI only pulls and displays the measurement data in the app for the fields that scale actually supports (the rest remain hidden), and If you want to the model specific data, you have to open that model’s UI in the app (For example, you are only going to see the arm measurements data in the body scan scale’s UI, It won’t be displayed if you open one of the other scales in the app because they don’t support the arm measurements, so they won’t show you that information in their UI page, even though the data exists in your Wyze account).
I should make one clarification with that though. The above is true for your main profile in your account. If you have multiple profiles in your account, such as pet profiles, or children or other people who don’t have their own Wyze account but we’re using a sub profile for the scale under your account, I think those don’t transfer over. You won’t be able to view the historical data for sub profiles from a previous scale model that weren’t using their own Wyze account. Your primary profile data will show up, but not the pet or other subprofile data. Most people won’t care about that, but I thought I should clarify, because mine have not transferred over for my kids or my cats when I set up a new scale, but all of my data does show up in the new scale, and my new scale data always shows up in the old scales too in the app.
No. It just “appends” new data.
As a clarification, I bought the original wyze scale in 2020, and I didn’t get the new body scan scale until 2025, but my body scan scale shows all my data accurately all the way back to 2020, years before it even existed.
I hope this is sufficient clarification to answer your question.
That would’ve been my expectation. Thank you for confirming that.
I think that’s an important clarification, too, and that’s also what I would expect. I wonder if that’s the experience @franks59 is seeing and trying to describe.
Are you saying that if you use the BodyScan, then open the Ultra (not BodyScan) device in the app, you do NOT see the Detailed Repot and Body Segment Data in the Ultra and the latest weight reading in the Ultra was the one where you weighed yourself on the Ultra and not the BodyScan?
Likewise if you then weigh yourself on the Ultra then open the BodyScan device in the app, you can still see the Detailed Report and Body Segment Report and if you then open the Ultra device, the Detailed Report and Body Segment Report are NOT showing there?
This is a known app syncing issue where both scales share the same user profile and measurement slot, so the most recent sync temporarily overwrites how the data is displayed. After the cloud finishes processing, it usually corrects one device but then flips the other, like you’re seeing. At the moment there’s no reliable way to keep both scales’ reports separate in the app for direct comparison unless they’re assigned to different user profiles.
That is how it used to work when I first used the new Bodyscan scale. I hadn’t checked recently, but after your insistence I checked now and it turns out they have updated the scale ultra and scale x UI now to show the Bodyscan data if the most recent entry was from the Bodyscan scale. Interesting. It didn’t used to do that when I first checked. I wonder when that changed. It doesn’t happen on the original scale UI, just the ultra and Scale X now.
Why do you say it’s a bug? From what I can tell, all the scales use the same database table to add new measurements to and then the app just pulls what all of the most recent measurements are and displays those regardless of which scale was used. It just shows what the most recent measurement was from, any device. But if I recall correctly when I was testing this out myself, the scale display itself only stores the local measurements for that exact device. So if you look at the history on the device display, it will show you the most recent measurement made on that particular device, but if you look in the app, it will always show you the most recent measurement from any scale on your account using the same profile. That is exactly how I would want it to work. I don’t think that’s a bug. Or do I misunderstand what the bug is? I think they have just updated a lot of the scale Uis to be more dynamic and show whatever the most recent measurement was. So if the most recent measurement was from the body scan scale, then most of the other scales measurements will now show the arm and leg measurements as well in their UI. They didn’t used to do this, but it looks like Wyze has updated them intentionally to dynamically display it when it’s relevant to the most recent measurement stored in the cloud table. I wouldn’t expect them to change that. Can you help me better understand why it should be considered a bug (in case I need to better explain your position to an employee to pass your feedback on to the scale product manager)? Any exact steps I should try to understand this better? (Note that I still have the original scale, scale X and ultra, but I rarely use them anymore because the Bodyscan is so great… But I still have them in the app… But if I need to pull them back out again and put new batteries in them to do a test from the old scales again to better understand the bug, I can do that).
Anyway, it’s actually a pleasant surprise to see they’ve updated the other Scales UIs to dynamically display the newer measurements when they’re relevant. I like it.
