All this “you can tap here” stuff is not intuitive. No one should have to read the directions (at least not more than once) or have the developer explain the app to them. I think there’s an entire Silicon Valley season about that.
Velocity - I need to know the range at which my bullet gets down to 1800 FPS. Below that, many bullets will no longer expand reliably. This is more important to me (and many RokSliders) than energy. That tells me whether I have a 400-yard rifle, 500-yard rifle, etc.
TOF is nice to have, since it tells me how much could go wrong between bang and impact. But not essential.
I don’t mind energy being there, but I don’t need it. I suspect that many of your users like knowing this number, even though it is useless to me.
I appreciate your willingness to listen to feedback.
Edit - if you have the ability for the user to customize the order of the columns, that would also be handy. Or even to disable some columns completely, that would be useful.
