Installed the Hornady 4DOF app on an iPhone 8+ yesterday. Worked fine yesterday. Set up all the data for one of my rifles and bullets and played with the Axial Form Factor to get the calculated come ups to match actual data.

Today, I started up the app and it is showing zero come up and zero windage, no matter what I do. Tried changing atmospherics, changing distance, resetting Axial Form Factor to 1.0...... nope, still displays zero.

Any ideas? It's like it's missing a "Calculate" button like on Strelok.
