Needs bugs fixed.

It’s a great concept,but needs the following fixed:
1. Won’t accept date change.
2. On screen cursor comes and goes.
3. When cursor is visible it is not coincident with location you point to on the screen, to pick target hits.

Excellent if you print targets and scan them

This app is great. Works for any caliber, any distance, any target, and it’s easy to use when you get the hang of it. I found the app works best with printing my own 8.5” x 11” targets that map to the A-25 specs @ 100yds—the distance I do most of my indoor practice. After the range, I scan my sheets on a flatbed scanner, transfer images to my phone, and then use the app—sounds complicated, but it’s easy and fast. Love being able to assess and adjust a zero in a scientific way. Also good for tracking progress and training. Overall, LOVE this app, highly recommended.
