Brimly Now Runs in Your Browser — Meet Brimly Web

Until now, Brimly lived on one kind of screen: your iPhone. Today it gets a second home — Brimly Web, a free fill-up and expense log that runs in any modern desktop browser. No account, no installation, no trial that expires: open the page, add a car, log a fill-up. And it keeps the promise the iOS app was built on — your data never leaves your device, because there is simply no server for it to go to.

Why a web version at all

A phone is the right tool at the pump — twenty seconds, scan the receipt, done. But some jobs want a keyboard and a big screen: typing in three years of old records, going through a stack of receipts at your desk, studying charts, or keeping the log for a car whose owner doesn't use an iPhone at all. Brimly Web is built for exactly those desk-side sessions. It is not a stripped-down demo of the app — it is a full log: garage, fill-ups, expenses, statistics, import and export.

Local-first: your data lives in your browser, full stop

Most web apps in this category start with a registration form, because your data is their business model. Brimly Web starts with an empty garage. Everything you enter is stored in your own browser (in IndexedDB, the browser's built-in database) and nowhere else. There is no login, no cloud copy on our side, no way for us to read your logs even if we wanted to — the web app makes no backend calls with your data at all. It's the same rule the iPhone app follows: no accounts, no user data on servers, ever.

The honest flip side: data that lives only in a browser deserves a backup. Brimly Web asks the browser for persistent storage, shows you how many records are not yet in any backup, and exports your whole profile to a single .brimlycar file at any time. In Chromium-based browsers (Chrome, Edge) it goes one step further: bind the export to a file on disk once, and the app rewrites that backup automatically after every change — a live, always-current copy you own.

What's inside

The log works the way the iOS app does, by design — the two share one data format and one set of rules:

• Garage — any number of cars, with make and model autocomplete from our public catalog.
• Fill-ups — enter any two of volume, price and total, and the third is computed; the form warns about an odometer that goes backwards or a suspicious figure before saving, not after.
• Honest consumption — computed only between full-tank fill-ups, the one method that doesn't lie; partial fill-ups and gaps in the history are handled correctly instead of skewing the average. Units follow your region: l/100 km or mpg, litres or gallons.
• Expenses — maintenance, repairs, insurance, parking, fines and more, with the same categories as the app.
• Statistics — a consumption trend with the factory-declared figure drawn right on the chart where we know it, fuel price over time, monthly spending, and a where-the-money-goes breakdown. On a 27-inch monitor, this is where the web version earns its keep.

Bring your history in minutes, not evenings

A log is only useful with history in it, so we put real work into getting yours in fast. Keep your records in a spreadsheet? Copy the table and paste it — Brimly Web recognises the columns, shows what it understood, and fills in the computable gaps row by row. Coming from another tracker? The importers read Fuelio, Fuelly and Drivvo export files directly, plus any generic CSV with a manual column mapping — duplicates are detected and skipped, so importing twice doesn't wreck the log.

It talks to your iPhone

Brimly Web and the Brimly iOS app exchange data through one file: .brimlycar. Export it in the web app, open it on the iPhone, and your desk-side work is in your pocket; export from the phone, open it in the browser, and your whole history is on the big screen. The web side already merges an incoming file into an existing profile — updates land in place instead of creating copies — and the same merge arrives on iOS with the next App Store update. No cable, no cloud relay, no account linking the two: just a file you control.

Works offline, installs like an app

Brimly Web is a PWA: after the first visit it works fully offline — the log opens, records save, statistics draw, with or without a connection. Install it from the browser menu and it gets its own icon and window, indistinguishable from a desktop app. It also speaks eight languages: English, Russian, German, French, Spanish, Italian, Portuguese and Japanese.

What it deliberately doesn't do

The AI side of Brimly — the assistant that knows your exact engine, receipt scanning, trip briefings, OBD diagnostics — stays in the iPhone app, where the camera, the mic and the OBD adapter are. The web app is the pen-and-paper half done properly, and that half is free, without ads and without a data price tag — with no servers storing your data, there is nothing to charge rent for. If you want a taste of the AI half without the app, the free web assistant on this site answers car questions right in the browser.
