Not sure which iPad you have? Identify your iPad model.

The only real alternative was manufactured by Adonit - but they have ceased production of Stylii that were compatible with older models of iPad.

The Adonit wasn’t a true alternative for Apple Pencil anyway - as it required specific support to be coded into third-party Apps.

Our resident expert on Stylus alternatives, MichelPM, will doubtless be along shortly to offer the benefit of his extensive knowledge of Apple compatible stylii.

To reiterate, your iPad5 is not compatible with Apple Pencil.
