### 3/5 — Nice App but Buggy

*2025-05-13, version 6.2*

Love the app but it is very buggy.

### 5/5 — Great App For $0

*2025-04-13*

This is a great app. Takes a little to figure out, but there is an included user manual. Great app that does what others do, but for a cost. Enjoy the app.

### 3/5 — A handy app

*2024-12-10*

A very handy app that allows you to mark your shots and have it calculate the grouping. I found it fiddly to learn but once you master it it’s quite useful. The interface is simple but there are some bugs in moving around and I found myself out at the beginning and not be able to get back to my results without starting a new set.

### 1/5 — Dont waste your time.

*2024-09-13*

App works maybe 1 time, if you are lucky. After that it is crash city. If it doesnt crash it never shows the green anchor needed to properly setup a target to be analyzed. Complete waste of time app.

### 5/5 — Outstanding

*2024-06-25*

Common guys, cut the man some slack :)

Its free and it does one thing well

I was doing this by bringing em into CAD
And scaling and dimensioning

I decided that was madness and installed a few apps

I was trying to do in federals ballistic deal for like 15 min and pulled this up and was done in 2

Take a picture w your camera of a target and import it and tap stuff until ya figure it out. 
If ya screw up, trash it and start over

I didnt read a thing. I just knew the picture had to be scaled and i had to pick the centers of the group

Its just ruler/+hole/+report

Ill figure the rest out later

### 4/5 — A very useful app

*2024-04-07*

I find SubMOA is very useful to analyze shooting targets. While not really user friendly it does a great job at a price that is well within anyone’s budget (free)

I wish someone can tell me what the metric SEC stands for. I know it was added as an analysis metric a year ago but there is no mention of what SEC means. If someone can tell me it would be greatly appreciated.

### 1/5 — Desenvolvedor não responde o suporte

*2024-02-18*

O desenvolvedor não responde o suporte do app

### 1/5 — Can’t get to work.

*2024-01-10, version 6.2*

Tried for 1/2 hour.  No luck.  Showed group size 0.0”.  
Instructions not clear to me.

### 2/5 — Lots of bugs and clunky but free and workable

*2023-10-05*

It’s a bear to change dates or ammo types or to even put data overlays but it all works in its own buggy clunky way. Lots of potential for improvement.

### 1/5 — Doesn’t even work

*2023-09-23*

App opens just fine but there is no way to even start the process of analyzing the target. Don’t waste your downloading something so nonfunctional.
