With three measuring modes and a digital display, the Bagel Smart Tape Measure ($70) will make counting tiny ticks and fighting a metal blade a thing of the past. Use the retractable string for when you’re measuring more than just straight lines, like a waistline, or flip it on its side and wheel it along any surface with one hand. For really hard to reach areas, point the ultrasonic sensor at a wall or ceiling to track the distance up to 16 feet. The Bagel will automatically save up to 100 measurements or can send them directly to your smartphone. A mobile app will organize and analyze your measurements and can help you create virtual blueprints, purchase the right size clothes, and keep track of weight loss. Its lithium polymer battery lasts up to 24 hours and can be recharged with any micro USB cable.
