Most of us don’t need a stylus to use our smartphones. But they are handy if you don’t want to leave fingerprints all over your device’s screen. The iRing Stylus is a cool ring you can put on your finger when you are not using it. Better yet, when you do need a stylus, this ring can take care of your needs. This aluminum and rubber ring is compatible with touchscreen devices such as iPhones and iPads.
