stylus for I-Pad

I have been frustrated with the difficulty of having patients sign the screen with our visit notes while doing home care.  The patient has difficulty getting the stylus to make a mark due to the angle of the stylus in use.  They often grasp the I-pad and place their finger on the Home Button.  They need to place the hand down to stabilize while writing and doing so causes the screen to move.  Sometimes they press too hard and a bubble shows up on the screen.  I have been on the hunt for a better stylus, one with a smaller tip.  I found this stylus on Kickstarter.  It is pricey and I will have to wait until January for it to come in but it is fun to support someone who is inventing an improved product.  Now I need to come up with an I-Pad holder that has a piece that can flip over when used for signing that will cover a portion of the screen – hovering just above the screen, so the patient can rest their hand on the cover while they sign. ..Something to invent!
