What scale are you using that syncs well with Apple Health? I'm using one I got on Amazon that had great reviews but doesn't seem to be very reliable. I can step on it and step back on it 5 seconds later and it'll give me +/- 3 pounds weight within seconds. Heck...I don't understand why Apple just doesn't make one. It would probably sell well.

We've been pretty happy with our Garmin Index. I like the on board memory and tracking for multiple users. When the temps start rising, I'll often weigh myself before and after a run/bike so I can effortlessly see my net sweat loss.

I love my renpho scale.
