The Perfect Drink App-Controlled Smart Bartending is a smart scale with a free app that allows you choose from hundreds of drink recipes and you follow real-time pouring instructions. Watch as a virtual glass fills on your smartphone or tablet, it measures your ingredients and compensates for those who like to pour with a heavy hand. Place your container on the scale, and it automatically sets itself to zero so you’re ready to pour. The Perfect Drink App-Controlled Smart Bartending automatically weighs each ingredient as you pour and alerts you when to stop.
