No, you can’t use any stylus with an iPad. Today’s styluses are high-tech writing tools with features like palm recognition, pressure sensitivity, and tilt responsiveness. To accomplish those features, the stylus will need to pair with the tablet. Some styluses will only work with Microsoft and Android devices, and some iPad styluses will only pair with the latest generation of Apple tablet. That’s why it’s important to read the specifications of any stylus to ensure it will work with your tablet. That said, if all you want is a simple stick for making marks and writing notes, you can use just about any stylus you want. But you’re giving up many of the fun functions of truly digital pens.
