Everything people ask before trusting a reloading log with their records — including the awkward ones. If something here is missing, email [email protected] and it gets added.
A reloading log and inventory tracker. It records what you have on the shelf, the load recipes you have written down from your own manuals, the batches you load, and what those batches actually did at the range — so a velocity or a group can be traced back to the exact powder lot, primer, bullet and brass that produced it.
No, and it never will. The app does not generate, interpolate, suggest, or “calculate up” a charge weight. It records the data you enter from your own published sources, and a recipe will not save without a citation for where the numbers came from.
If you enter the published minimum and maximum from your manual, VectorX will warn you when a charge you typed sits outside the range you recorded. That is a comparison against your own reference — not advice. Always work loads up from a current published manual.
The logging app is free and stays free: unlimited recipes, batches, inventory, firearms and range strings, chronograph import, printable batch labels, and the full brass lifecycle. There is no round limit, no recipe limit, no watermark, and no advertising.
VectorX Pro adds the analysis layer on top — charge and accuracy ladders, progress trends, cost per round, barrel log, target photos, the printable load book, and cloud sync across devices. It is $14.99/year, or a one-time $27.99 Founder’s Lifetime for the first 250 supporters, $41.99 after that. Prices are shown in US dollars.
The web app at vectorx.expo.app works today in any modern browser, on desktop and on a phone. An Android release is in preparation; iOS follows. It is one codebase, so the app is the same on all three.
Yes. Everything is stored on the device and the app is fully usable offline — logging a string in a paddock with no bars is the normal case, not an edge case. If you have Pro and an account, syncing happens whenever a connection comes back.
No. The whole logging app works with no account and no sign-up. An account exists only to sync between your devices, which is a Pro feature. If you never sign in, your data never leaves the device.
On your device. In the web app that is your browser’s local storage; in the mobile apps it is an on-device database. Without an account there is no copy anywhere else — not on a server, not with us.
If you subscribe to Pro and sign in, your records are also stored in our database (hosted by Supabase) so your other devices can read them.
None of it. There is no analytics SDK, no telemetry, no crash reporting, no advertising identifier and no advertising in the app. This site carries no tracking scripts either — no Google Analytics, no pixels, no cookie banner, because there is nothing to consent to.
If you never sign in: no, categorically — it is not on any server I control.
If you use Pro sync, the honest answer is the one every cloud service owes you. Your rows sit in a database I administer. Other VectorX users cannot read them — access is enforced per account at the database level. But I hold the administrative credentials, so I could query the table, in the same way the operator of any hosted service could. I don’t, and nothing in the system does it automatically. You are trusting an operator, and you should decide whether that is acceptable rather than take a marketing sentence for it.
If it isn’t acceptable, use the app without an account. That path is deliberately not a lesser product — it is the full logging app, and your data stays on your hardware.
It is never sold, shared, or transferred to third parties, and it is never used for marketing or profiling. There is no data-sharing arrangement with anyone — no retailers, no manufacturers, no advertisers.
On the question people are usually really asking: if you never sign in, I hold nothing about you, so there is nothing that could be requested from me. If you do sync, your records exist on hosted infrastructure and, like any business, I am subject to the law of the place I operate in. I am not going to pretend otherwise on a page about being straight with you.
Your email address, which is used only to send one-time sign-in codes. There is no name field, no address, no phone number, and no password. If you buy Pro, Stripe processes the payment and we keep only the customer reference needed to know your subscription is active — card details go straight to Stripe and never touch our servers.
Yes, and it is immediate. Settings → Account → Manage account → Delete account permanently removes your synced records, your target photos, your profile and the login itself — not a soft delete or a 30-day queue. If you have a subscription it is cancelled at the same time, so deleting an account can never leave you being charged for one that no longer exists.
Two things survive, and you should know which. The records on your own device stay there — deleting the account removes our copy, not yours. And the payment itself stays with Stripe, because transaction records have to be kept for tax and accounting; we hold nothing about you after deletion.
Without an account there is nothing to delete on our side: uninstalling the app (or clearing the browser’s site data) removes everything, permanently, with no copy anywhere. Take a backup first.
Yes, but by hand rather than automatically. Deleting the account removes the record that links you to the purchase, so signing up again gives you a fresh free account. Email [email protected] from the address you bought with — the payment is still on file at Stripe, and Pro gets put back on your new account.
If all you want is to stop syncing, Sign out is the better button: it leaves your purchase and your records alone.
Yes, both. Settings → Backup → Download a backup writes every record you have — inventory, recipes, batches, firearms, range strings — to a single readable JSON file you keep wherever you like. Restore from a backup puts it back, on this device or any other.
Restoring is deliberately additive: it adds records the device has never seen and updates ones the file has a newer copy of, but it never removes anything the file doesn’t mention. Importing an out-of-date backup therefore cannot roll your recent work back.
This matters most if you don’t have an account. Without one there is no copy of your log anywhere but that device, so clearing your browser’s site data would take it with them. A backup file is the answer, and the app will remind you if it has been a while.
Pro also prints a load book — every recipe with its source, results and development history — as a real document for the bench.
Charge and accuracy ladders drawn from every shot you recorded; progress trends per load and per firearm over time, including the full development history across every version of a recipe; cost per round from the prices you put on your lots; a barrel log with round counts and shots since cleaning; target photos attached to range strings; the printable load-development book; and automatic cloud sync between your devices.
Every one of those is a rendering of records you already made. None of them produce load data.
Nothing is taken away or locked. Your records stay on your device and stay fully usable — you keep logging recipes, batches, inventory and range strings exactly as before. What stops is the Pro layer: the ladders, the trend charts and cloud sync. Start paying again and they come back.
A reasonable question to ask a one-person operation before paying for anything. The app runs entirely on your device and needs no server to work, so an installed copy keeps working whether or not anything new ever ships. Nothing about your existing records depends on a subscription being alive or on me being around.
That is also the reason the free tier is a complete app and not a trial: the thing you rely on at the bench shouldn’t be the thing that switches off.
Because early supporters carry more risk than later ones — backing an app before it has a track record is worth something, so the first 250 pay less for it. The lifetime option itself does not disappear: once those 250 are claimed it stays on sale at the standard price. What runs out is the discount, and the server enforces that from a ledger of actual purchases rather than trusting the copy on this page.
LabRadar (the SR#### Report.csv from the SD card), Garmin Xero C1 Pro and C2 (export a session from ShotView), MagnetoSpeed (LOG.CSV from the memory card, and the XFR app export), and Athlon Rangecraft.
You never tell the app which chronograph you own — it reads the file and works that out. Metric exports are converted to fps automatically, and if the file holds several series you pick the one you shot. Importing is part of the free app. Garmin .fit files are not read yet; export a CSV from ShotView instead.
A case only counts as fired once you have actually fired it. Loading a batch takes the cases out of stock along with the powder, primers and bullets — they are loaded rounds now, sitting in the box. After a range string the app asks how many of the cases you fired came home; those return to inventory as one firing older, and the ones that split or got lost in the grass simply don’t come back.
Delete a batch you never shot and every component goes back to the lot it came from.
Powder and bullet weights are grains, lengths are inches and velocity is fps. You can enter powder purchases in kilograms, grams or pounds and it converts for you. Nothing is ever displayed as a bare number without its unit.
Any batch can print an ammo-box card carrying its recipe, component lots and a QR code. Scan the code at the range and the log opens pointed at exactly those rounds, so the string you record is attached to the right batch without you typing anything.
One person: Keith Milton, an Australian reloader who has written software for a living for fifteen years. VectorX started as the log I wanted for my own bench — one record that followed me from the PC to my pocket at the range, instead of a notepad, a spreadsheet and a memory that never quite agreed.
Support emails are answered by the person who writes the code. There is no team behind that address and no support script.
There is no catch, and it is worth being specific about what that means. The whole logbook is free with no account, no ads, no tracking, no round or recipe limits, and no watermark — and it keeps working forever whether or not you ever pay.
VectorX Pro is the analysis layer on top, and it funds the servers, the storage and the time to keep developing this for years rather than months. If Pro never appeals to you, nothing in the free app is switched off or nagged at to change your mind.
Please do, on both counts. For press, club newsletters or a forum thread, email [email protected] and ask for whatever you need — screenshots, a walkthrough, or a straight answer to something awkward that isn’t on this page.
