Lapua Ballistics

I have been using this for .22lr. I have 5 kinds of ammo that I measured velocity for. After I entered all the ballistic info in this app has been spot on for all of them.

Great format, easy to use but moving targets calculator is not working.

Review is on UI only. No opportunity to test solutions yet. I MOSTLY like the UI. Great approach, graphics ranging from OK (POI chart) to great (drop plots and options). I really dislike entering values in a text box at the bottom of the screen as opposed to directly in the field of interest. I also had to re-start the app after changing my units (I went from pure metric to mixed units). Even more critical, the click value changes I entered didn't take effect until after a restart. I like the two-part calc window and how it zooms on touch. The ability to keep the solution in the upper part while scrolling additional views and info on the lower part is well-done, IMO. Bottom line - slightly clunky. Still plenty of functionality opportunities. The app would benefit from a round table of expert users with the developer.
