***Thank you for viewing!*** This is an automatic pendulum for smartphones. Brand new, unused item. This device uses an electromagnet to swing and increase step count. The built-in electromagnet keeps the pendulum in perpetual motion, allowing the swing to continue. It's a lightweight, thin, and latest-model type, and the pendulum axis uses ball bearings for improved quietness! It can swing with two smartphones, so you can share it with friends and family! It increases step count for smartphone apps like Pokémon GO, Walkr, Dragon Quest Walk, and Google Fit. Depending on the situation, it can automatically earn approximately 5,000 to 7,000 steps per hour, so it's recommended because you don't have to earn steps yourself while doing housework, working, sleeping, or studying. Operation is easy: connect it to a USB power source, secure your smartphone with the included rubber band, and then just swing the pendulum with your finger, and it will move automatically. Power is supplied via USB. Please use the included USB cable, etc. If your smartphone settings are not configured correctly, the steps may not be counted, so be sure to make changes and take measures. Please note that you cannot use it without performing the above steps. It supports various models of iPhones, Androids, and others, but please use it with smartphones that are 6 inches or less. Width: 9cm, Thickness: 1.6cm. Color: Black. As this is an imported product, there may be minor scratches or scuffs, so please refrain from bidding if you are concerned about minor details.
