Everything that ships inside
No hidden paid modules, no "upgrade to see this". This is the full list, and all of it travels on your device from the first time you open it.

- 1,157real clinical images
- 316calculators with their formula
The material, at three depths
The same guide reads as Essential the night before an exam and as Full the month you prepare a rotation. It is not a different summary: it is the same text, unfolded.
730 guides across 40 subjects
From basic sciences to the clinical specialties, all sharing one structure so you never have to learn how to read a new one.
- Three levels: Essential, Intermediate and Full
- Figures and tables inside the text itself
- Cross-linked with the atlas and the calculators
2,778 exam-style questions
Each with an explanation of why the right answer is right and — more useful — why each distractor is not. That is where the learning happens.
- 1,430 MIR-style
- 593 Step 1-style · 755 Step 2-style
- Timed and subject-filtered mock exams
9,926 revision cards
Spaced repetition over what you have actually studied, not a generic deck with no idea where you are.
- 5,075 short revision questions
- 48 guided study paths
- Revision adapts to what you get wrong
The tools you use standing up
Everything computed here shows its formula and its reference. A clinical calculator that hides its source is a number with no surname.
316 calculators
Scales, scores and conversions, each with its formula, its interpretation and the study it comes from.
34 clinical algorithms
Step-by-step decision trees for the situations where the order of things matters.
372 drugs
Monographs by active ingredient across 21 systems: mechanism, indications, adverse effects and interactions.
1,082 symptoms
Differential diagnosis starting from the presenting complaint — the way a patient arrives, not the way a syllabus is ordered.
1,876 clinical cases
Complete vignettes to practise the whole reasoning chain, not keyword spotting.
9,659 terms
Embedded glossary: any underlined term opens its definition without taking you out of the page.
Currency and corrections without reinstalling
References declare their year, and content can be corrected through signed packages. Guides update by replacing text and data, never by executing code received from the server.
Content no longer lives in silos
Epistemis links what you study to how you practise it, what evidence supports it and where its limits lie. The full index and reproducible labs run locally.
Cross-cutting medical graph
Groups every topic by intent: understand, visualise, practise, apply, remember and review evidence. A connection means semantic relation, not causality.
Evidence and research
A source registry, PICO, reproducible PubMed queries, local PDF analysis, biostatistics and diagnostic tests in one workspace.
Local Dataset Lab
CSV data, types, missingness, a dictionary, SHA-256 fingerprint and deterministic charts without transmitting file rows.
Auditable Evidence Watch
Compares guideline versions and retains an editorial queue. The engine is ready; automatic publication remains closed until reliable sources and review exist.
With consistency, not marathons
- Daily mission and streaks: 62 achievements that reward coming back, not cramming.
- A mistakes notebook: what you get wrong keeps returning until it stops catching you out.
- Per-subject progress, so you can see what is green and what you have been avoiding.
- Everything syncs across devices if you create an account. The account is optional.
What it does NOT do
It does not diagnose, it does not prescribe, and it replaces neither current clinical guidelines nor a professional's judgement. It is study and revision material — and the app says so on every screen where that could be confused, not just in the terms.
730 guides that fit
in your pocket
Each at three depth levels, with highlighting, your own notes and a search that survives typos. The same source, at whatever level you need that day.
Where it actually gets used




A question bank tells you whether you got it right. A textbook tells you why. Here you do not have to choose.
All of it, with no signal
There is no "limited offline mode": the whole thing is on your device from first launch.
