The anaesthetic logbook that works offline.

Log a list between cases on your phone — in an anaesthetic room with no signal, on a Sunday night, wherever you actually are. Your logbook stays on your own device. There is no account to make.

It installs to your home screen like an app — no App Store, nothing to download. The guide shows you how, in one step.

It works with no signal

Everything is on the device. A basement anaesthetic room is exactly where you need to log a case and exactly where your phone has nothing.

Nothing is uploaded

No account, no server, no analytics. Your cases never leave your phone unless you export them yourself.

No patient can be identified

There is no field for a name, a hospital number or a date of birth. Age is stored as a number and a unit — a record reads 70 years, never a birthday.

What you can do with it

Where your logbook lives

On your phone, in the app's own storage, and nowhere else. That is what makes it work with no signal, and it is also the one thing to be careful about: if you lose the phone without a backup, you lose the logbook. Clerked reminds you when it has been a while — take the reminder seriously.

The full detail is in the app under Settings → Your data, written to be read in two minutes and forwarded to anyone who asks.

Clerked is free while we build it together. It is made by a practising anaesthetist, and it is shaped by what other anaesthetists ask for. If something is missing, slow, or in the wrong place, please tell me — that is genuinely how it gets better. Signing in on more than one device is what we are working on next.
