Ballistic X

You don’t need this app to determine group size or even offset from center. You can do this with a ruler and eyeball estimating. Even CEP is easy by hand. What would be great is a statistical estimate of variation from the group center…not only standard deviation but also 95% probability. For example if you have 9 shots through the same hole and one shot two inches away, that’s a two inch group. But statistically it’s a very small group and that’s more meaningful. An app can make this calculation but it’s hard to calculate by hand. Please consider adding this sophistication

It used to be 5 stars when it was supported. Now, on iOS 12, it won’t even start. On iOS 15, it asks for a login. The description here says it has a “not now” option for the login; it doesn’t. If it’s there, it’s layers into some login path. Developer’s website would not load, so no longer supported apparently. UPDATE March 18, 2024: With the release of version 2.0.0, I’ll bump it back to 5 stars. I can continue on without signing in now. I think the interface is a little cleaner and more intuitive. It doesn’t resolve my issues with iOS 12, but that could be due to an older phone’s capabilities. Still wish it would work though, even with the old version.

Was a great app for a long time. Really liked being able to put multiple POA / groups on a single picture. Would have liked to see a feature where you can select two points for scale then have a pop up ask you how far apart they are, rather than having to always use a set value. The 2-stars come from the latest update when ruined the accuracy and my trust. I don’t know what’s wrong but I did a tall target test which should have been 44” high and +/- 0.25” windage. The app gave me 2.63” high and 1.7” right. Nowhere near accurate. Ran it multiple times to ensure no user error. A rollout like this, especially for a paid app, is unacceptable. The core function is ruined and a simple test would have shown them immediately.
