The reloading log that keeps the whole story.
From published recipe to loaded batch to range results — one traceable record, with your inventory counted down along the way.
Load recipes, versioned
Every recipe carries its source citation. Edit a recipe that has been loaded and VectorX creates a new version — the exact load behind every batch is preserved forever.
Full traceability
Recipe → batch → range results, linked end to end. Print a batch card with a QR code at the bench, scan it at the range, and the string logs against the exact rounds you fired.
Inventory that counts down
Powder, bullets, primers, and brass tracked by lot. Logging a batch decrements the components it consumed and flags shortfalls — and brass lives its full life, with fired counts and post-firing case recovery.
Chronograph statistics
Enter velocities shot by shot and get average, extreme spread, and standard deviation per string — compared across loads and sessions.
Range log with ratings
Group sizes, star ratings, and conditions per string, rolled up to the recipe version that produced them — so load development decisions are based on records, not memory.
Offline-first, yours
Everything lives on your device and works with no signal at a remote range. No account required, no ads, no tracking.
VectorX never generates, interpolates, or recommends load data. Your published reloading manual is the authority — the app records the data you enter from it and requires a source citation on every recipe.
Validation only compares your charge against the published range you entered, and warnings never silently block your work. Powder and bullet weights are always shown in grains, lengths in inches, velocities in feet per second — never a bare number without units.
Automatic cloud sync
Sign in once and your devices stay in step by themselves — start a load at the bench on your desktop, log the strings at the range on your phone. The app stays fully usable offline with no account.
Load development analysis
The charge ladder drawn from your own recorded shots, automatic round counts and a barrel cleaning log per firearm, true cost per round from your lot prices, and a printable load book. Your data, analyzed — never generated.
Pro subscriptions are coming soon — simple pricing, and everything the app does today stays free.
