INROThe app for clinicians. All of it, offline.
688 medications, step by step syringe preparation, cardiac arrest mode, your courses and your shift planner. For nurses, nursing students, nurse anesthetists, nursing assistants and physicians.
On the ward or still in school
INRO adapts to your job, your profile and your training curriculum.
What is waiting inside the app
Real screens from the app, exactly as you will see them on your phone.
The right dose, no mental maths.
Pick the drug, the ampoule and the diluent. INRO walks you through the recipe step by step: the volume to draw up, the syringe, the final concentration. The syringe fills up before your eyes, with an ISO colour label.
In cardiac arrest, one single button.
Timer, compression metronome at 110 per minute, time stamped shocks and drugs, a resuscitation checklist, and a PDF report at the end. Giant buttons that work with gloves on. Cardiac arrest mode is free.
Every medication, at a glance.
688 monographs: indications, adult and paediatric dosing, dilutions, contraindications, IV compatibility. Fridge storage, dosage form and crushing rules are shown right on the sheet, and high alert medications are flagged.
Your shift planner, in your pocket.
Your shifts, your days off, your hours. Compare your schedule with a colleague using a short code: shared days, possible swaps, common days off. Everything stays offline.
Lab values and critical thresholds.
136 lab values with low and high critical thresholds, sorted by family: haematology, coagulation, electrolytes and more. Plus 88 device alarms explained: ventilator, syringe pump, dialysis, monitor.
Everything to get through nursing school
Revision, training progress and clinical skills logbook.
Your nursing course, semester by semester.
Every placement, every module passed, every skill in the logbook: the app keeps count for you, from semester 1 to semester 6. Placements, modules and 68 technical skills.
Revise anatomy with 66 blank diagrams.
Name every structure, then switch to mock exam mode: 5, 10 or 15 boards drawn at random, timed, with no answer shown before the end. Plus 60 fill in the blank texts, flashcards, quizzes and clinical cases.
Do not confuse. The detail that matters.
Two look alike notions drawn side by side, and the one detail that tells them apart. Erythema or purpura, and 19 more pairs, in dermatology, respiratory care and cardiology.

The questions we get asked
What is INRO?
INRO is a clinical drug reference and preparation tool for registered nurses, nursing students, nursing assistants, nurse anesthetists, perioperative nurses and physicians working in emergency medicine, intensive care and critical care. A free mobile app, fully offline, ad free, built by a French registered nurse for his colleagues.
What is the best app for nursing students?
A nursing student needs three things: revising anatomy and pharmacology, drilling drug dose calculations, and tracking their training. INRO covers all three: 66 unlabelled anatomy diagrams, 60 fill in the blank texts, 66 courses with an audio reader, flashcards, quizzes, a timed mock exam mode, 35 dose calculation tips, and progress tracking for placements, modules and the 68 skills of the clinical logbook.
How do I calculate a syringe pump rate?
The calculation depends on the prescribed dose, the patient weight and the concentration of the prepared syringe. INRO walks you through the preparation step by step: which ampoule, which diluent, what volume to draw up, what infusion rate in mL/h. Conversions (mg/h, mcg/kg/min, drops per minute) are automatic.
Does INRO work without an internet connection?
Yes. Every piece of data ships inside the app and works offline: medications, protocols, clinical scores, lab values, courses. Essential in resuscitation rooms, basements, on scene, in dead zones and in remote settings.
Is INRO free?
Yes. The free plan includes 63 medication monographs, the full cardiac arrest mode, 5 essential scores and a selection of courses, with no ads and no time limit. Premium comes in two plans: 9.99 euros a month with no commitment, or 49.99 euros a year, about 4.17 euros a month. The yearly plan includes a 7 day free trial.
Does INRO work on iPhone and Android?
Yes, on both. The app is available on the App Store for iPhone, iPad and Apple Watch, and on Google Play for Android.
Can paramedics, EMTs and nursing assistants use INRO?
Yes. The clinical scores, emergency protocols, cardiac arrest mode, handover tool and the glossary of 429 medical abbreviations serve everyone in care and prehospital response, not only nurses.
Can nurses outside France use INRO?
Yes. The app is available in English, French, Dutch and German and works anywhere, since it runs offline. International nonproprietary names are universal. Content is sourced from European guidelines and French medicines agency product summaries, and should be cross checked against your own institution's protocols.
Does INRO collect patient data?
No. No patient data is collected or transmitted. Everything you enter, including training progress and shift planning, stays on your phone. The app works with no account and no sign up.
