It’s free so you can’t really complain

- You can’t zoom in enough to properly mark shots.
- The X axis is reversed so you’re constantly moving the cursor in the wrong direction. It should have the same orientation as the native photos app.
- The instructions are very sparse.
- It should automatically add the details when you finally save the group. Having to remark everything because you didn’t add the details is frustrating. Especially because of the reversed X axis.
- The graphics for the marked shots get in the way of marking other ones. It needs to hold off on adding them until you’ve marked all of them.

Very Useful!

It took me a while, but I finally figured out how to make full use of the app. It’s a wee bit buggy, but for a free app, I am certainly not complaining. This app is very useful for ascertaining the exact POI of your group and thereby leveraging the most consistent result from your firearm by sighting in 100% correctly. A rifle is easy to sight in when groups are small cloverleafs. However, when things open up a bit and there are “flyers” involved, it is a little more difficult to nail down your exact POI. This app makes quick work of figuring that out, and has quite a few extremely useful features hidden under the hood if you have the patience to fully learn how to use all of the features of the app. I’m really impressed!

Fun Tool for Air Gunners Too!

The app doesn’t target air gunners, but it can help take friendly competition among air gunners to the next level! It’s both feature rich and cost effective. There is a short learning curve but the fun is worth it.

I gave it four stars because of occasional crashes. Since the app allows loading target photos, I suggest taking target photos with the Camera app so that those aren’t lost to crashes.
