Ballistic X - Group Size

Hello all!

I have been incredibly busy with an accidental day job I began during this past 1.5 years. As a consequence, Ballistic-X has been neglected and I have dropped the ball in being the kind of Company I intended. (Clearly the App does not generate enough income for me to retire and do just the App). I have no excuses! For the past year, I bet I have gotten 3-5 emails per week requesting the Advanced Toolkit with Mean Radius I promised almost one year ago. There are SO many other features I intend to offer as part of the Toolkit that just are not in the cards immediately, but will come as funds allow. The original $7.99 spent gives one the App, in its current form, for life. Its already had several features added at non additional cost to users. The Toolkit will have to be something that generates something steady for Development, otherwise it will not sustain. I will be launching it at $9.99/yr which will be a discount from the $19.99/yr aim. Once I arrive there, I intend to have auto-processed targets, multi-group targets, etc. For now though, I need to produce SOMETHING for everyone who has supported the App! The Advanced Toolkit is really only for ~5% of the current Audience I expect...but it needs to exist!

On Monday, May 23rd, the next iteration of the App will be launched. I will then be facilitating any bugs as with initial launch. This is tedious, but I have not had the time to do this well until recently. I am here. The App is not going anywhere, and I promise to do better!
 
I appreciate your transparency and honesty. Hard to find these days where blaming and excuses seem to be the norm.... Thank you.

As far as I am concerned: you're forgiven (another thing that seems to have gone "out of style").


And I will gladly pay $10 annually for some of the more advanced features — up to $20/y if the app really does everything (short of pulling the trigger, that is....😄).


This is good news! 👍🏼

Since I'm new to this and using your app I have to ask the following:

MEAN RADIUS as compared to GROUP: Can you briefly describe the differences and how the info is intended to be used??

I do have input about the app: When using the OVERLAY and ADD LABEL feature I can't seem to place the label at the top of the data panel. I like to place the cartridge/bullet info within this data panel. Just something I noticed when using the app.
 
That helps, but I'm not a math wiz by any stretch. I understand the definition (hence the big picture), just not sure on some aspects of the info the app gives us.
I'm just trying to understand the key differences of MEAN RADIUS as compared to GROUP as given by the app results.

The app is saying I'm holding a .55"MOA MEAN RADIUS and 1" GROUP. Is the term GROUP the same as saying EXTREME SPREAD?

I'm not a deep diver in PS. I'm just a tadpole.

I think this article does a little bit better explaining them along with some graphics:

 
So GROUP and EXTREME SPREAD is the same while MEAN RADIUS is it's own.
I understand what the data/numbers are giving me now. Thanks to all who replied!
 
New features coming for the App, weigh in on new thread:

Some questions. I have an Android and the paid version of the app.

1) How do I delete pics & info out of the History? Some of the processed pics that appear in History are mislabeled, but I can't seem to delete them.

2) How do I save a pic? Some of my pics, once I've added all the info, save fine, but after about 13, they're not saving any more. I get to the place where I can add a label, I do so, I hit Save and I get to a screen where I can crop or rotate the image. Don't want to do either, but now I'm stuck in the screen and there's no way out. At the very top of that screen there's a checkmark and an X at opposite corners, but they are unresponsive. What am I missing?

Other things to consider.
Library is misnamed. It seems to point to generic stored pics on the device, near as I can tell. The library of the app would be more logically a storage area where old processed pics are kept, not where ALL pics on the phone are kept. Recommend that this is called something more intuitive like "Phone pics."

History is misnamed. A history is normally a list of actions and time stamps, not a list of processed pics. Recommend that this be called Library.

Get the free Hornady app and never look back. I've used them all and there is none better, it includes something called Zero Angle which is a new way of getting your zero.


Does the Hornady app measure the mean group size or CEP — or only the inefficient "extreme group spread"?

If it does, I am interested!! 👍🏼

Here's a picture of the measuring data from the app. The mean radius is what it gives you, which is the average distance of every shot from the center of the group (the circled white X).

Note: I used to use CEP a lot, but that involves a minimum of like 20-shots to get a decent answer. As my shooting progressed I now need what the Hornady app provides, which is how far off I'm from the center of the target and the mean radius. In this case the target size is1/4 MOA center and 1/2 MOA circle. Each red square is 1/2 MOA (at 100 yards). Notice I have an exact distance of 106 yards (that's my laser measured range and it makes a difference).

JAS-SH, 🫱🏻‍🫲🏼

thanks a lot for your input — yeah, mean radius would be sufficient for me.


Now, I tried to find the app in the Google Playstore, but I don't seem to find it:
One is a ballistic trayectory app,
the other a reloading data collection. Nothing mentioned about measuring precision of shot groups....
What am I missing? 🤔

Thanks,

Matthias

As far as I can tell, you get the Hornady 4DOF app for free. On its home page is a button for the Group Analysis which you have to buy for $4.95...at least in the Apple store.

Me...I think a phone is not a terminal and I use OnTarget (for like $11-12) on my PC. Just me.
