Eatsmart (400 Lb Capacity Silver Precision Tracker Digital Bathroom Scale Product Details As studies have shown, tracking the progress of any weight loss regimen is vital for providing real-time feedback and increasing motivation. With the new AccuTrack software from EatSmart, monitoring weight changes has never been easier! EatSmart' s propriety AccuTrack software allows users to monitor both short term and long term progress. After a brief initial setup, the individual will weigh themselves and the scale will log the starting weight into memory. On each subsequent weigh-in the individual will step back onto the scale and get three results: 1) Their current weight 2) The change in weight from the last time they weighed themselves 3) The total change in weight since first use. The Precision Tracker Scale stores up to 8 different users' personal profiles and will be able to recognize these users as soon as they step onto the scale. The Auto Recognition software automatically locates your user profile based upon the proximity in weight to your last weigh-in. The Precision Tracker uses "Step-On" technology which means no more tapping to turn on your scale. It measures up to 400lbs and will display an accurate readout to the nearest .2 lbs. on the oversized 3.5" LCD display. Its sleek design and slim profile fits perfectly into any surroundings.
