A:Answer Go to www.logi.com/grab-a-crayon for the complete compatibility list. I have a 7th generation iPad, 2019, 10.5”, I think. The Logi crayon did not have to be paired like with Bluetooth devices. It does have to be charged. It works well with Procreate and my two other drawing apps, meeting my needs. When in doubt, I would suggest contacting Logitech or the developer of the 3D Sharp app.
