** This app is the remote control for DragonScale, our smart scale product** Prepare to know everything. You’ll know how many cards people are holding, how many are red, black, the suits. You’ll even know the sum of the cards in their hands. Know which objects are where. The routines possible are so strong that they could astonish people who have seen creatures of myth and legend. This is DragonScale from Penguin Magic. A top-secret project at Penguin Magic for five years, the DragonScale is a patented smart scale hidden inside of a card box that is so sensitive it can detect the slightest differences in weight down to a single card. The information the DragonScale learns is sent to the app that converts weight into details that create unreal revelations. This precision-made prop operates in stealth and feeds you real-time information so that you can focus on your presentation. It’s the closest you will ever feel to having actual magical powers. How does it work? Our precision-engineered smart scale communicates directly with our the app via Bluetooth, no manual pairing necessary! Just turn on the scale, open the app while near the scale, and a connection will be automatically established! The app is preloaded with popular card stacks like Mnemonica, Aronson, and Si Stebbins and allows for custom stacks and arrangements. Place the stacked deck on the box and have your spectators cut off packets of cards, then wait for the information delivery. You read that right, spectators. Plural. Multiple people can remove packets of cards, and precise information about each packet is delivered to your smart device (we included watch support for people who really want to fly under the radar). Then reveal the exact information you want at your leisure. Whether it’s the exact card they cut to, the number of cards in their hand, or even how many cards are red or black. You aren’t just limited to cards. DragonScale can be set up for custom weight arrangements. That means three objects can be placed on the card box. You turn your back, and when a participant removes an object, you will instantly know which one is taken. The applications with this incredible device are limitless. Tip the scales of astonishment in your favor with DragonScale by Penguin Magic.
