Smart squeeze ball measures your grip strength
You may not give your grip strength much thought, but it's important for many daily tasks, and for lessening the chances of developing repetitive strain injury. A new "smart" squeezable stress ball is intended to help you build that strength – and the device is known as Squegg.
Featuring a soft silicone rubber body, Squegg's onboard electronics include pressure sensors that measure how tightly (and how many times) it's being squeezed. The ball utilizes a Bluetooth module to transmit that data to a free iOS/Android app on a paired smartphone, where it's displayed in terms of reps and pounds/kilograms of force.
The app also allows users to track their grip-strength-building process over time, and be guided through workout routines. Should they feel so inclined, they can additionally engage in online challenges with other users.
Squegg itself is water-resistant, weighs 66 grams (2.3 oz), and can reportedly run for around 80 hours on one two-hour charge of its lithium battery.
If you're interested, it's currently the subject of a Kickstarter campaign. A pledge of US$29 will get you one in your choice of two colors, when and if it reaches production. The planned retail price is $39.
