Here is another scale that gives you more insight into your health & fitness than just your weight. The Omron Body Composition Monitor works with iOS and Android devices. It tracks body weight, fat %, visceral fat, skeletal muscle %, resting metabolism, and body mass index.
The device has memory to store 30 readings for up to 4 users. It can handle users up to 330lbs. The BCM-500 has a large enough LCD display for you to look up your readings easily.
