This rechargeable Active Electronic Pencil by #ABsuper is compatible for my grandson's iphone and tablet and he's really emjoying using it. He's used it for quite a while now and so far he's used it for writing as well as drawing and doodling. He's recharged it several times over the past few months and so far this one hasn't given out. We've spent more on other stylus pens that haven't lasted nearly as long! At $27.99 this is a good price.
