Buggy, incomplete, difficult to use

This app could be great, but there are just too many downsides that make it more trouble than it's worth.
1) No handload data fields
2) POI and bullet hole placement marker doesn't match where the marks land when you click the button.
3) Firearm and Ammo library doesn't work at all
4) no analysis, such as ladder or OCW methods.
5) editing saved shot groups loses all the shot group data even though they are still on the image. Forcing you to completely start over even if all you want to do is change a notes field.
6) no way to sort or otherwise re order the list of groups on the analysis page ( not an analysis at all, just a list of entered groups.
7) no actual session information even though it asks you to enter session data (I.e. You can't look at groups by session)

Many more. At the end of the day, all you can really do is calculate group size and group MOA. The exported images are goofy because the bullet hole overlay illustrations are in the wrong place and done actually overlay the holes.

Terrible app

Although the idea is great I see the the author abandoned this app completely. The support page doesn’t work on website. There is virtually no any place you can address your concerns to. The only thing you can do is calculate the group size. Cloud is a complete failure. Nothing works. I will dispute this charge with bank not to return money - 4 usd is a small amount but not to support such approach on AppStore

Just not complete!!

The difference between this app and the free app is the reloaded cloud support which does not work. Get this working and add name tags to notes, like instead of just 0.51” (0.54 moa)
Add the tag Group size: 0.51”, etc.
