Built on principles

Systems, not superheroes

Safety comes from well-designed systems, not from expecting clinicians to perform perfectly every time.

Complement, never replace

These tools support your judgement. They never override it.

Reduce mental load

Free your working memory for the decisions only you can make.

Blood Gas Pro

See the reasoning, not just the answer.

Traditional analysis requires mental arithmetic that's prone to error under fatigue. This app takes you from raw values to a coherent physiological explanation, step by step, with visible working throughout.

CodeClock

Run the arrest. Don't let the arrest run you.

At its core, a timer that tells you when you're due for a rhythm check or adrenaline dose. Behind that, it quietly guides you through the ALS algorithm with drug doses, ECMO criteria, and time-based prognosis data all in one place. It manages the algorithm, giving you brainspace to manage the room.

IntubAid

A checklist that thinks with you.

A digital intubation checklist that adapts as you go. Identify an aspiration risk and it helps you choose mitigations, then carries them forward so you remember to verbalise them with the team. Multiple team members can prepare in parallel — so the checklist keeps pace with the team, not the other way around.

LabLogic

Structured interpretation for common investigations.

Lab results don't arrive with an explanation. LabLogic walks you through the interpretation systematically, surfacing the differentials that matter. Hyponatraemia, thyroid function, iron studies, LFTs, and coagulation — with the right questions, in the right order.

Scott is an intensive care doctor, Certified Practitioner in Human Factors in Healthcare, and currently completing a fellowship in quality and patient safety. His background in psychology and clinical governance informs a straightforward conviction: that the greatest gains in patient safety will come not from training individuals to be more vigilant, but from designing systems that make safe care easier to provide, and errors harder to commit.
