Lindcott Armory

The spreadsheet breaks down around gun four. The notes app was never built for this.

Lindcott Armory tracks your full collection: round counts, sessions, ammo inventory, and optic assignments. All without requiring you to maintain a filing system on the side.

Everything is free. No subscription, no paywall, no ads. Unlimited guns. Log every range session, every ammo lot, every gun in your vault. Round counts update automatically as you shoot. Get alerts when you need to order more. It works fully offline, and your vault stays on your device.

The heavier tools are free too — they just need a free account, which also syncs your vault across your devices. The AI assistant runs on Claude and knows your specific vault — ask it maintenance schedules, load questions, cartridge comparisons, without having to explain what you own every time. Reloading assistance builds a recipe for each gun based on your goals rather than handing you a generic starting node. Every shot group you submit gets a full breakdown: MOA, CEP, extreme spread, standard deviation — numbers you can actually use when you're working a zero or running a load test. Track which loads or ammo work best for which guns and get alerted when something is out of whack.

Plus get great reference guides on every cartridge, powder, and factory load. Compare ballistics between calibers to find the right tools for you.

No social features. No ads. No reason to open it except your guns.
