Measure Group Sizes Precisely with Ballistic-X SmartPhone App

Ballistic-X Apple (iOS) version shown. There is also a Ballistic-X Android App.

Here’s something all shooters need — a smartphone App that calculates bullet-hole group sizes from your own photos. The Ballistic-X App is simple to use. Take a photo of your target, set some values (such as bullet diameter and distance to target), then use the touchscreen to place circles around each hole. The App will calculate group size (in MOA or Mils), distance to point of aim, and provide all the info in an overlay. Then click “save” to record your group for posterity!

This App works well, is relatively easy to set-up, and costs just $7.99. It is available for both Android devices and iOS (Apple) devices. There are other ways to measure group sizes from target images, such as the excellent On-Target program, which we have used for years. However On-Target requires a software installation on a Windows platform desktop or laptop. Ballistic-X is a simple, easy-to-install App with versions for both Android and iOS (Apple) Mobile devices.

The Ballistic-X App has a relatively easy-to-use interface. Of course you can choose either MOA or Milrad group values, and Inch or Metric dimensions. There are various labeling options that provide useful info for Load Development. There is even an ATZ (Adjustment To Zero) feature for adjusting your turrets.

How to Use Ballistic-X App

1. Select Photo Source — Choose Camera to take new photo or get image from Photo Library.

2. Set Reference Values — Select Bullet Diameter and enter Distance to Target.

3. Establish Scale on Image — Mark two points on target photo to set scale.
For example, if the target has a 1″-square grid lines, mark two points on grid for 1″ distance.

4. Mark Point Of Aim — Put the central X on the aim point.

5. Designate Shot Locations — Place the green circles around each shot.

6. Finalize Data Display — Position Overlay, select size/color options, and export file.

Android Options — Range Buddy FREE App
Along with Ballistic-X, there is another Mobile App, Range Buddy, that also measures shot groups. Range Buddy is currently offered for Android devices only. It is FREE, but has adverts. Range Buddy isn’t bad, but users complained about the program crashing, and there are compatibility issues with newer phones. We recommend you pay $7.99 and stick with Ballistic-X.
