Quick answer: The Armorer App is the privacy-first iPhone-and-iPad gun-maintenance tracker that logs every round, every cleaning, every parts change, every range session, and every modification across every firearm in the owner’s collection. The Armorer App runs entirely on-device with no server-side database of the user’s collection. Armorer Pro ($49.99/yr) unlocks unlimited firearms, advanced reporting, custom maintenance schedules per gun, and PDF export. The Day 43 prize package includes a one-year Armorer Pro subscription.
Armorer App: The Firearm Maintenance Tracker Built by a Gun Owner for Gun Owners
Armorer App is a powerful, purpose-built mobile app that serves as a complete digital armory assistant for responsible firearm owners. Developed by Luke McCoy, the founder of USA Carry and a competitive USPSA shooter. Armorer App was born out of real frustration with tracking round counts, maintenance schedules, and gear details in a simple spreadsheet. Available on both iOS and Android, the app turns scattered notes and mental checklists into a clean, automated system that helps you stay on top of every firearm, suppressor, optic, and accessory in your collection. Whether you’re a daily concealed-carry holder, a suppressor enthusiast, a reloader, or someone who simply wants to protect your investment, Armorer gives you professional-level organization in the palm of your hand.

What the Armorer App actually does & What Problems It Solves for Firearm Owners
At its core, Armorer App solves the everyday headaches that every serious gun owner eventually faces. It automatically tracks round counts by letting you log range sessions with full ammo details (manufacturer, type, grain weight), instantly updating running totals for each firearm and attached suppressor. You can set custom service intervals based on round count or calendar dates and receive timely notifications like seven-day advance warnings plus overdue banners so you never miss a spring replacement, deep clean, or baffle inspection again. The app maintains a complete service history, logs modifications (triggers, barrels, sights, grips), and even lets you attach suppressors, optics, lights, and other gear as individual items with their own maintenance schedules. Additional features include ammo inventory tracking with automatic deductions and low-stock alerts, photo galleries (with EXIF data automatically stripped), and secure document storage for receipts, warranties, and insurance records. In short, Armorer eliminates the chaos of forgotten maintenance, lost round-count data, and disorganized paperwork, turning “I think I’m due for a cleaning” into precise, actionable knowledge that keeps your firearms reliable and ready.
The Privacy-First Architecture: Why This Matters
In an era when many apps collect and monetize user data, Armorer takes a radically different approach with its privacy-first design. Serial numbers are protected by true zero-knowledge encryption using AES-256-GCM, with the encryption key derived directly from your password, meaning only you can ever read them. The developers (including Luke himself) literally cannot access your serial numbers, and nobody else can either. Photos have all GPS and location metadata stripped before upload, there are zero ads, and your data is never sold, shared, or used for advertising. You can permanently delete your entire account and all data from inside the app at any time with no email required. For firearm owners who often deal with sensitive information like serial numbers, home addresses on receipts, and detailed inventories, this level of privacy isn’t just a nice-to-have; it’s essential. It gives you peace of mind that your personal armory data stays exactly where it belongs: with you.
Armorer Pro vs the free tier
The Armorer App ships with a free tier that covers up to three firearms with basic logging. Armorer Pro unlocks the full feature set:
- Unlimited firearms. Free tier caps at three; Pro removes the cap.
- Advanced reporting. Round-count totals, session summaries, parts-change history, ammunition-lot correlations, custom report exports.
- Custom maintenance schedules per gun. Set a recoil-spring replacement interval at 5,000 rounds on a Glock 19 and have the app warn when the round count crosses the threshold. Different schedules per firearm; different intervals per scheduled task.
- PDF export. The full firearm record exports as a PDF maintenance history — the document a gunsmith asks for on a warranty claim or an insurance appraisal.
- Multi-device sync. Pro subscription unlocks iCloud sync across the user’s own iPhone-and-iPad set (still no server-side BAM/Armorer database).
- Priority support. Direct contact channel to the Armorer App team for issues.
The Pro tier runs $49.99 per year. The Day 43 winner receives a one-year Armorer Pro subscription as part of the prize package.
The Armorer App runs entirely on-device. There is no server-side database that holds the user’s firearm inventory. There is no cloud sync of serial numbers to a third-party server. There is no analytics pipeline that aggregates firearm-ownership data into a corporate dashboard. The data stays on the iPhone or iPad it was entered on, encrypted, accessible only by the user.
For the gun-owning population in 2026, this architecture matters. The 2024-2026 wave of cloud-service data-breach incidents, combined with the legitimate concern about how firearm-ownership databases might be used by future political actors, has put a meaningful premium on personal-data products that simply do not have the data to lose. The Armorer App is in that category by deliberate architectural choice, not by accident.
The iCloud sync option in the Pro tier is opt-in and uses the user’s own Apple iCloud account. Apple end-to-end encrypts the synced data; Armorer App still has no server-side access to the records. The sync replicates between the user’s own devices and nowhere else.
