About this app

Armorer is a firearm maintenance tracker built by a gun owner, for gun owners. Started as a spreadsheet. Became this.

Whether you own one gun or twenty, Armorer keeps everything organized in one place — round counts, service history, ammo inventory, modifications, gear, photos, and documents.

Round Count Tracking

Log every range session with ammo details including brand, type, and grain weight. Running totals update automatically for every firearm in your collection.

Service Intervals

Set cleaning and maintenance intervals by round count or time. Armorer notifies you before service is due and shows a banner when something is overdue. Think of it like oil change reminders for your guns.

Maintenance History

A complete service log for every firearm. Know exactly what was done, when it was done, and how many rounds ago. Perfect for resale documentation.

Modifications Tracker

Log every aftermarket part — triggers, barrels, sights, grips, slides, and more. Document what makes each gun yours.

Gear & Accessories

Track optics, lights, lasers, and accessories with their own service intervals. Set battery replacement reminders. Attach gear to a specific firearm or manage standalone.

Ammo Inventory

Track your stock by brand, caliber, type, and grain weight. Set a custom low stock alert per ammo type. Ammo deducts automatically when you log range sessions.

Photos & Documents

Add photos to any firearm, gear, or ammo entry. Attach receipts, warranties, and insurance documents. All photos are automatically stripped of GPS location data before uploading.

Privacy by Design

Serial numbers are encrypted using AES-256-GCM with a key derived from your password. We cannot read them. Nobody can. Your data is never sold, shared, or used for advertising. No ads. Ever. Delete your account and all data permanently from within the app at any time.

Built by Luke McCoy, founder of USA Carry — one of the largest concealed carry resources in the United States.

Ratings and reviews

I have a Pixel 10 Pro. Runs fine. I added about 2 dozen firearms with pictures for each. It even has an inventory and accessory tracker and maintenance tracker, if so desired. I'm not retentive enough to count the rounds sent downrange in each piece of mine along with cleaning schedules. That said, the yearly price is too steep for me to jump on considering I'm just using it for inventory purposes only. Maybe if there was a lower tier, I'd jump. Exporting works great to CSV.

the only way to add data is to download the template then import it back in to the app. The add buttons are non existing on Pixel 10XL. Doesn't appear to be worth $50 per year

As another reviewer stated this does not appear to be a good and tested application in Android phones. Same problem, blank screen and no plus sign to add anything. With the ability of Android Studio to mimic all sizes and brands of phones this is inexcusable.
