MedSimMonitor (iOS)
Simulation Made Simple.
Turn your iPhone or iPad into a fully functional patient monitor — no hardware, no setup, no internet required. Built for healthcare educators who work in the real world.
High-fidelity simulation should not require a high-fidelity budget.
MedSimMonitor gives instructors real-time control over physiological parameters directly from an iOS device. It is lightweight, offline-first and designed for exactly the kind of resource-limited environment where clinical training matters most.
Features
Works Without Wi-Fi
Fully offline. No internet dependency means it works in skills labs, rural training centres and anywhere else your teaching happens.
Real-Time Instructor Control
Manually adjust physiological parameters on the fly to drive your scenario forward without breaking immersion.
No Hardware Required
Replace expensive monitor simulators with a device you already own. At 2.5 MB, it takes seconds to install.

MTS Paediatrics | Medical (iOS)
Malaysian Triage Scale for Paediatrics. Made Easy.
Built for the triage desk. Designed for the real world. Practice paediatric triage decisions directly from your iPhone — no cost, no login, no data collected.
Triage is a skill built through repetition. MTS Paediatrics puts that repetition in your pocket.
Triage is a skill built through repetition. MTS Paediatrics puts that repetition in your pocket.
The app helps emergency triage staff practice placing young patients by acuity, based directly on how they present. It is grounded in the Malaysian Triage Scale 2022 and built to sharpen the pattern recognition that matters when a child walks through your ED doors.
Features
Grounded in MTS 2022
Not generic triage logic. MTS Paediatrics is built specifically on the Malaysian Triage Scale 2022 — the standard your department actually uses.
Pattern Recognition Training
Repeated exposure to varied paediatric presentations builds confidence in spotting acuity differences before they become critical decisions.
Designed for Quick Practice
Short, focused decision scenarios fit into shift breaks, orientations and pre-shift warm-ups without disrupting workflow.
Free. Private. Lightweight.
2.2 MB. Zero data collected. No account required. Works on any iPhone running iOS or later.
mNNJ (iOS)
NNJ Training and Reference
Neonatal jaundice assessment does not have to be complicated. mNNJ trains you to handle it — simply, quickly and with confidence.
Neonatal jaundice is one of the most common conditions in newborn care. Knowing what to do when you face it — and doing it fast — matters.
mNNJ walks you through the assessment process in a structured way, building the decision-making muscle you need at the bedside. Choose the approach that fits your setting: the CPG method or the Paeds Protocol method. Both are built in.
Features
Two Clinical Pathways, One App
Use the CPG approach or the Paeds Protocol approach — whichever your unit follows. mNNJ supports both so training stays aligned with actual practice.
Training-Focused Design
Not a lookup tool. mNNJ is built to train you on what to do when faced with a case of neonatal jaundice, step by step.
Simple and Fast
No cluttered interface. No unnecessary steps. Designed to be picked up and used immediately by anyone in a clinical training context.
Free. Private. Lightweight.
6 MB. Zero data collected. No account required. iPhone only.
PEWS Vitals (iOS)
Calculate PEWS. Vitals Range.
Age-appropriate paediatric vital signs and a built-in PEWS score calculator — in 1.1 MB, on your iPhone, for free.
Paediatric vital signs are not a single set of numbers. They shift with every age group, from birth to 18 years. Getting them wrong — or looking them up too slowly — has consequences.
PEWS Vitals puts age-based normal ranges and a structured PEWS score calculator in one place, with transparent point allocation so you understand the score you are looking at, not just the number it produces.
Features
Age-Based Vital Sign Ranges — Birth to 18 Years
Instantly view what is normal, mildly abnormal or critically abnormal for heart rate, respiratory rate, blood pressure, temperature and oxygen saturation across every paediatric age group.
Built-In PEWS Score Calculator
Enter observed vital signs and generate a structured PEWS score with clear point allocation. No mental arithmetic. No ambiguity.
Designed for Education and Clinical Awareness
PEWS Vitals is built to support safer interpretation of paediatric vital signs in learning and clinical contexts. It is not intended for diagnosis, treatment or independent clinical decision-making.
Rated 5 Stars. Tiny Footprint.
1.1 MB. Zero data collected. No account required. iPhone only.
