Smart scales?

I have the Withings total body analyzer. I love it! as for the body fat% I dont know how accurate it is. Mine has been changing as I lose weight but it is different within a percentage point or two daily. I think it is more of an estimate

I have the fit bit aria - love it!! However we had to work out some ticks at first lol
I found out after much frustration that it has to be stored flat or it will have to re-configure every time which gives you false readings. I now store it flat and it has been within 2 ounces of my other scale. I weighed myself with both for a month or two to make sure before completely switching We also tested it using weights for accuracy and to see how sensitive our stance would be. Regardless of how you shift your weight (if you tend to put more weight on one side of your body) it did not make a difference...still gave the correct weight. My other scale sometimes was touchy with that sort of thing.

My husband and I both use it and it uploads our weight when we do - to the correct account. No issues there

Edit to add - i do not pay attention to scale body fat % as I do not believe they are accurate at all to begin with

I have the Aria scale and the fitbit. I step on my scale first thing every morning and then it just syncs with all of my programs... MFP and fitbit automatically have the data and there's no way that I can fudge it! I also have mine synced with Trendweight (trendweight.com) because it gives me great stats. Basically it finds what your trend is over time, so if you fluctuate back and forth a bit it doesn't feel like you've gained two pounds, rather you're still the lower weight with 2 lbs of bloating or a belly full of food.

The scale seems to be accurate and matches within a pound or so of other scales I've used. The only awkward thing is the reporting on MFP. If I go up a pound and then regulate back to the lower weight the next day, it says that I've lost a pound. So basically, even though I've dropped about 40 lbs in total, the daily reporting makes it look like I've dropped like 100 pounds. people have congratulated me on losses that aren't really losses, rather normal up/down fluctuations. I know I can change that setting, but I haven't.

All in all, I'm really glad I have my Aria because it keeps me honest, I can see patterns with my choices and it really works with my laziness as far as reporting weight change. I've also had it about a year and haven't had to change the batteries!

Best of luck!

I have the Fitbit Aria and I love it so far! Had a little trouble setting is up with my home WiFi but once I took the batteries out it reset and worked.

I love that it syncs with my Fitbit dashboard (I have the Fitbit Flex), MyFitnessPal and also my employee Virgin Health Miles account without me having to go to a million sites to update them.

I'm thinking the body fat is spot on as well.

Good luck with your scale shopping.
