Add more Body metrics besides weight.

You have body weight and I see you are planning on adding more metrics.

You also say in the weight info that check how your pants fit to see if they are loose. Meaning your weight can stay the same or even increase when you add muscle. So checking your waist line will let you know if you are losing fat. In general. It would be nice to be able to add the waist measurement for tracking. And possibly a fat% I use a scale and look for trends not absolutes. Possibly other measurements for tracking.
