Good enough

Perfect for what I do. I am in the steel fabrication industry and for my railing pickets this is perfect. You might have to fudge the last picket a tiny bit sometimes but for what I need it is quick and easy.

Put in exact measurements and used there centers,they started getting further off and last picket was off

Hardly industry leading

Since all of the 5 star reviews for this app are obviously fake, I thought I would be the first to give a “real” review. The good... The visual representation of the handrail is nice as it lets you see exactly what you are entering, but personally I don’t like the number input method. It is intuitive, well laid out and easy to use. The not so good...Only gives you the centers of the balusters...only gives you two types of handrail options... maximum spacing is limited to 12”....200” is the maximum run which is somewhat limiting........1/16” is the smallest increment you can use which is useless if you want to cut a pile of fillets.... $7.99? Seriously? There are much better baluster apps out there at a fraction of the cost. On its own I would give this app 2 or 3 stars because it is a bit limited but since the developer posted a bunch of bogus reviews to make it look better than it really is, I figured I would give it one star.
