Your iPad already comes with everything you need to play games, draw, write, and do everything in between. An Apple Pencil can make you even more productive on your tablet but it is not super cheap. The NovaPlus A8 Duo is a more affordable stylus for smooth, lag free writing and drawing. It has embedded magnets to clamp to the side of your iPad.
The A8 Duo supports palm rejection. It also features tilt awareness, so you can control the width of your line easily. This stylus can be charged in about 40 minutes via USB-C (or wirelessly). It has replaceable tips. It has a back end button for one-click shortcuts for apps like Procreate. With its charging case, you can get up to 12 hours of battery.[where to find it]
