One Swiss Knife in the exact shape of your life.

Practice Log

A private practice log in one HTML file on your machine: no account, no cloud, no server to talk to.

Live · runs in your browser · no network

This is not a screenshot. It's the real tool, running right here: go on, put something in it.

Forged into a knife, this tool ages with use: the blades you reach for wear soft, entries you tend keep their bloom, and the years travel with the file through every reforge.

The scales don't practice themselves, and the weeks have a way of evaporating. The Practice Log keeps a plain account — the piece or exercise, the minutes, the date — so that "I've been practicing, roughly" becomes something you can actually look at.

What it keeps

Standing facts

In ten years

Whatever you put in (Piece / exercise, Minutes and Date) stays inside the file itself. There is no account to lapse, no plan to be sunset, no migration e-mail with a deadline in it. A decade of practice log entries is a decade of your own handwriting, kept in a document you can back up like any other.

If Offline.Ltd closes tomorrow, nothing on your machine notices. That isn't a marketing promise; it's simply what a file is.

Getting your data out

Export to CSV from inside the tool and open it in anything: a spreadsheet, another app, a text editor. Or keep the HTML file: it is plain, readable, and inspectable; you can open it in a text editor and see your own rows sitting there. No export queue, no "we'll e-mail you a link within 48 hours", no format that only one vendor can read.

Copy the file to a USB stick, a NAS, a folder your devices already sync. It runs on Windows, macOS, Linux, Android and iOS, online or off, because a browser is the only thing it ever needed.

Who else sees this

Nobody. Your Piece / exercise, Minutes and Date never leave the file on your own disk. There is no account, no telemetry, no analytics, and no code in the file that opens a network connection, pull the cable and watch it carry on working. How privacy works across the Hobby tools →

Questions people ask

01

How do I track my music practice time?

After each session, one line: what you worked on, how many minutes, and the date. The list does the remembering; the accumulating minutes do the encouraging.

02

Does this practice tracker require an account or app store download?

Neither. It's a single HTML file that opens in any browser and runs offline. Nothing leaves the page, and the file is yours forever — it will outlast the app stores.

03

Is this good for tracking a child's instrument practice?

Very. Three fields is about the right amount of bureaucracy for a nine-year-old, and there's something quietly motivating about watching your own minutes stack up. The demo on this page is live — try logging a session.
