Know exactly what you own.

GunCollector keeps your firearms, ammo, NFA items and accessories in one place — and it works at the range, in the safe room, and anywhere else your phone has no signal.

ADD A FIREARM FROM A PHOTO
Take a picture and GunCollector identifies the make, model and caliber and fills in the specifications for you to review. Scan the serial number with the camera instead of typing it. Ammo, accessories and NFA items can be added from a photo too.

YOUR WHOLE COLLECTION, IN YOUR POCKET
Photos, serial numbers, purchase details, notes and receipts for every item. Search and filter the collection, and see firearms, rounds on hand and estimated value on the dashboard.

RANGE TRIPS AND ROUND COUNTS
Log a range trip and the rounds you fired are deducted from your ammo inventory and added to each firearm's cleaning counter automatically.

MEASURE YOUR GROUPS
Photograph your target, mark the holes, and GunCollector calculates group size in inches, MOA and mils, plus mean radius.

DOPE CARDS
Create and edit DOPE cards for each rifle and keep them with you — no printouts to lose.

NFA RECORDS
Track suppressors, SBRs, SBSs and other NFA items with their paperwork photos, so your records are on your phone when you need them.

MAINTENANCE
Round-count-based cleaning reminders and a full maintenance history for every firearm.

WORKS OFFLINE
Your collection is stored on your phone, so everything is readable with no signal. Changes you make offline sync automatically when you're back online.

PRIVATE BY DESIGN
• Your offline copy is encrypted on the device.
• Optional fingerprint or face unlock and optional screenshot blocking.
• Location data is stripped from every photo before it's uploaded.
• No ads and no ad tracking. Your data is never sold.

WORKS WITH THE WEB APP
Everything syncs with GunCollector on the web at guncollector.app, where you'll also find insurance valuation reports, reloading records and chronograph import.

GunCollector is a record-keeping tool for firearms you already own. It does not sell, list or transfer firearms or ammunition.
