One Swiss Knife in the exact shape of your life.

Workout Log

A private workout log in one HTML file on your machine: sets, reps, weight, and how it actually felt.

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 body remembers the training, but not the numbers — and the numbers are where the progress hides. Workout Log is the plain gym notebook, kept in a tab: write down what you did while the chalk is still on your hands, and let the honest record accumulate. Progress you can look up beats progress you have to remember.

Standing facts

In ten years

Whatever you put in 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 workout 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.

Questions people ask

01

What can I record in the Workout Log?

Your workouts, plainly — what you did, kept as a running record you add to after each session. It's the paper gym notebook, minus the paper and the coffee stain.

02

Is the Workout Log for beginners or serious lifters?

Both, because both need the same thing: a trustworthy record of last time. Beginners see how far they've come; veterans see whether the plan is working.

03

Does the Workout Log work offline at the gym?

Yes — it's a single HTML file that runs in your browser with no signal, no account, and no fitness platform attached. Your training data stays on the page, in a file you own forever.
