How We Chose: Buying Guide
Match features to the task: highlighting and margin notes need only palm rejection plus tilt, which budget pens cover well, while pressure sensitivity matters only for illustration and heavy sketching. Latency and diagonal accuracy decide handwriting feel, so test fine-tip pens in GoodNotes or Notability during the return window. Flat anti-roll shapes survive lecture-hall floors best.
Check compatibility before checkout because most third-party pens support iPads from 2018 onward but exclude some Pro generations. Remove thick glass protectors if strokes skip, charge over USB-C, and disconnect rival Bluetooth styli fighting for connection. Magnetic attach keeps pens on the iPad edge; otherwise add a case pencil holder.
Pair the pen with a searchable workflow: GoodNotes, Notability, OneNote, Freeform and Acrobat all take stylus markup, while Zotero plus Acrobat keeps paper highlights searchable for essays. Keep spare nibs in the bag, store the pen cased with the iPad, and consider Find-My models if you lose gear often. Keep spare nibs cased with the iPad and store the pen magnetically so annotation gear never goes missing.
