One Swiss Knife in the exact shape of your life.

Use cases

Swim Log (where it earns its place)

On Swim Log:

Swimmers count laps the whole way and forget the number in the changing room. The Swim Log keeps each swim — date, laps, which pool or open water, the temperature in degrees, and notes for the day the lane was gloriously empty. … On this page: three concrete ways someone who wants a private record of their own body reaches for the Swim Log, and the signals that tell you it fits.

When the Swim Log earns its place

As a tracker, the Swim Log keeps date, laps, pool / water, and water temp (°c) — no more, no less — so the record is small enough to actually read back.

Most tools in this category, MyFitnessPal at $79.99 a year and Cronometer at $59.99 a year, or $10.99 a month, solve a version of the same problem, then bill you for the privilege of remembering it. The Swim Log takes the opposite bargain: one file, once, kept.

Three scenarios drawn from health, fitness, and water

The everyday one: you open the Swim Log on a Tuesday morning, log what needs logging, and close it. Two minutes. The record is more honest than the app that pinged you to remind you.

The specific one: the everyday task it's built to hold, day to day — the workflow it names is the record that most needs a home outside a subscription. Some people use only the Swim Log. Some fold it into a Swiss Knife next to five others. Both are correct.

The out-of-band one: months later, you want to look back. The Swim Log still opens because it is a file. There is no login lapsed, no export deadline missed. The record is where you left it.

Signals it fits someone who wants a private record of their own body

You want a health record that behaves like a document, not a service. You are comfortable typing your own numbers in. You would rather own the file than rent the log. Weight in the knife: 1. Manual: no manual — the tool is its own instructions.

Questions people ask

01

Can I log open water swims as well as pool sessions?

Yes — the pool or water field takes anything from the local leisure centre to a particular bend in the river, and the water temperature field is there for those who insist on knowing exactly how cold they were.

02

Is this a full replacement for MyFitnessPal?

For the working core of what most people use it for — keeping date, laps, pool / water, and water temp (°c) — yes. For food logging without the ads, no. The Swim Log is deliberately smaller and more honest about its scope.

03

Who is the Swim Log not for?

Someone who wants a private record of their own body's opposite: a team that needs shared cloud state, or someone who wants automation over ownership. Use a SaaS for that; use this for the file.

A health record that opens where you left it, on the machine you left it on.
