First, the app does not collect, mine, harvest or do anything with your data. Firearm information is just as sensitive as your social security number or credit card information.

Second, the app has a passcode. It is activated by using the iOS Settings App.

"Paper and pen at the range? Unnecessary. Gun Log lets you store all your firearm data…", American Warrior, issue Number 5.

Gun Log tracks firearms, ammunition, configurations, failures, rounds fired, costs, accessories, etc., and even can calculate a ballistics drop table.

Gun Log will never allow email to access the data, use printing, or use cloud storage, just as promised. Many users are careful about where their private data is stored and Gun Log was made for those. It was promised that those features would never be added and that is the way it will be. Please be aware of this policy, it has always been this way.

Units are only in U.S. yards and inches. There is no metric or other measurement system support.

Before you buy please go to the Developer Website and read about the App. The link is listed in the App Store. This app is not a simple list but instead an app that logs range results, ammo usage, firearms, ballistic drop tables, and has reports that allow you to analyze your shooting, firearms and ammunition, and improve your ability and to know what ammunition is reliable and accurate. You do not have to use all of the functionality, but it is there when you need it. Don’t let the low price fool you, this is a very complete range log and inventory app!

Outstanding job on this app!!!!


Clearly a considerable amount of time and attention to detail went into creating this app. It’s easy to use and you don’t need WiFi to use it. As the developer recommends, follow the instructions to backup your data. This is probably one of my favorite apps. I love it!!!!

A questionable app


I spent considerable time inputting all the information concerning my firearms to create an in-depth record of my firearms and with the very next update to the app, lost every bit of data relating to my collection. The long hours spent in getting every detail right were wasted. After the database disappeared a second time, I’ve decided that one way or another, it’s simply not worth the effort or the aggravation. Who knows where the information regarding my firearms went to.

Developer Response

I am sorry your data was lost. It truly is a lot of work to enter the data. That is why there are directions of how to backup the database. Did you contact us and tell us the steps you took? We have not had anyone lose their data that followed the backup directions.

Awesome App

JL Calouro

This app is fantastic, it helps me track the history of my guns (shots fired, cleaning, etc) and it tracks ammo usage and costs, plus a bunch of other things. I use this app all the time. Awesome update to the app! Perfect in every way.
