I have a professional dedicated one and I also use a couple of apps on my iPhone.
The iPhone apps when compared with polar alignment using pole-master were so close it was negligible.
Where I was out with the iPhone was the true-south compass direction not inclination.
So I would give the free app try first as well.
But as dedicated inclinometer should in theory be better......
