The smart in the name is a joke, they are kidding, the scale is pretty dumb.
2.4 out of 5 stars on Amazon (I have promised myself not to buy anything below 3 starts)
The scale loses all of its settings after 48 hours. Repairing fixing it.
Wait 48 hours, a magical guest measurement appears.
The physical user interface on the scale is completely cryptic. The scale's bluetooth profile on the iPhone has to be removed and re-added every time I want to manually sync because the one that's saved doesn't work on reconnection attempts. Most of the time the scale gives you feedback (a pictogram) that a child's weight was recorded and the user recognized, but synching to the "cloud" rarely happens. Yes, the scale is configured correctly and all other devices sharing the same wifi network work just fine. Most of the time I have to write down the weight by hand just to be sure in case synching doesn't happen. If I have to do this by hand why spend so much more for a smart scale?
Just extremely lousy software quality, lousy user experience and interface, cheap looking hardware (about the same quality as any digital bathroom scale), lousy and crashy iPhone app. I'm returning or trashing this thing. Maybe I will take it to a shooting range and use it for target practice.
At the beginning, it was working great. I saw the avg rate of the scale but I was thinking that it was due to first version of the firmware, but I was wrong... latest firmware is still causing trouble.
At the beginning (June 2015), My wife and me were very happy of this purchase, but, after 1 month, issues arrived.
It started with pairing issues with the Iphone 5S of my wife, then the scale was always starting in kgs instead of lbs, every time I had to spend 5 minutes to resynch the scale with the phone of my wife, then our son was considered as a "guest" by the scale....
After 1 week with everyday the same problems, we decided to return the product.
For this price, you shouldn't have this kind of issue. The software of the scale doesn't seem to be well optimize/written and the support is very slow to answer to our concern.
If you decide to purchase this product, be at least aware of the risk ! :)
Beware Withings! The product is great until it breaks. They have acknowledged that some of these are faulty but never respond to my requests for help!
