Why log

Why baristas write things down.

Coffee is a sequence of small variables. Without a record, every morning is guesswork.

01

Yesterday's perfect shot is today's mystery.

What grind setting was that? 12, 12.5, 13? Without a log, the next dial-in starts from zero. With one, it starts from yesterday.

02

The bag changes; you should know how.

New bag, same dial-in — usually wrong. The log shows you which beans needed coarser, which finer.

03

Trends beat tastes.

Every brew tastes good or bad in the moment. The 14-day score trend tells you whether you're actually getting better or just having a good week.

04

Top-beans-by-score is a shopping list.

After 30 brews, the topList shows you which beans are worth re-ordering. Stop buying the ones that average 5/10.

Inside the file

Eight things you'll use every day. Plus a dozen more.

One file. One dashboard. Every feature you'd expect from a "real" app — without the cloud, the cookies, or the £8/month.

  • Quick add

    Log a brew from the home screen — three taps and back to your day.

  • Live insight banner

    The single number that matters today, computed in real time from your entries.

  • Top beans (30d)

    Ranked list updated every time you log — the leaders surface naturally.

  • Searchable, sortable list

    Every entry findable in seconds — search across notes, sort by anything.

  • Rating system

    Star or scale ratings per entry — the patterns surface in the dashboard.

  • Cross-entity links

    Reference one entity from another — relationships stay intact across edits.

  • Light + dark theme

    Auto follows the system, manual override available in settings.

  • Empty states that explain

    Every list tells you exactly what to do when it's empty.

Offline, always

Loads once, runs forever without a network connection.

Installs as a PWA

Add to home screen — opens like any native app.

CSV in / CSV out

Bring your old data in. Take everything with you. No lock-in.

No account, ever

No email, no signup, no analytics, no third-party tracking.

Yours forever

If we vanish tomorrow, your tracker keeps working — local file, no server.

Light + dark

Auto-follows the system. Or pick one and stick with it.

The promise

Your dial-in notes are yours.
Not a social feed.

01

Offline, always

Open it once, never need the internet again. The file holds the whole app.

02

Local-first storage

Every entry stored in your browser, on your device. No server sync. No leaks. Nothing to breach.

03

One payment, forever

No subscription, no upgrade tier, no nag. If we shut down OneFileClub tomorrow, your file keeps working.

Data does not sync automatically between phone and desktop

This is a local-first app — everything stays on the device you logged it on. To use it on both phone and desktop, use the built-in JSON or CSV export on one device and import on the other when you want to keep them in step.

Every view, light and dark.

A look at every screen across both themes — your tracker, populated.

Questions

Real answers, no fine print.

Can I track multiple grinders / machines?+

v1 doesn't have a dedicated equipment field — most people note it in the brew notes. If demand is there we'll add it.

Will it work for filter-only setups?+

Yes. Espresso vs. brewed methods are first-class — the dose/yield/time fields adapt.

Where is my data stored?+

Locally, in your browser, on your device. Nothing is sent to OneFileClub or anyone else — there is no account, no cloud sync, no analytics.

Does it work offline?+

Yes. Once your personalised copy loads the first time, the entire tracker runs from a single HTML file. Airplane mode is fine.

What does 'personalised copy' mean?+

When you buy, OneFileClub stamps a private copy with your licence and deploys it to a unique URL just for you. You bookmark it, install it as an app, or save the file — and the file is yours, even if OneFileClub disappears tomorrow.

What is your refund policy?+

14 days, no questions asked. Email us, we'll process it and disable your private URL.

One payment.
Every Tuesday morning, dialled.

We'll personalise a copy and email you a private link. Bookmark it, install it, log this morning's brew.
