I use an Androit Dash 3 active stylus with iWork Apps on my iPad 2017. It is a fine point stylus that is more precise then the fat rubber tipped stylus. I paid $40 on Amazon. Unlike the Apple Pencil, it is not Bluetooth connected, so it does not have built in palm rejection, pressure sensitivity, and other smart features. On the plus side, it does not need to be paired and does work with pretty much any touch device.
Anyway, it works just fine for marking up documents and taking simple notes.....pretty good for productivity apps and very simple sketches, but not great for art and drawing. With this “budget pencil”, I can easily double tap on a word and drag the handle to highlight text that can easily be edited, copied or moved. The fine point makes a big difference.
Someday, I will need to update my iPad. At that time, I can decide if the Apple Pencil is worth the price premium over this less expensive alternative.
