Patient monitor simulators, side by side
Ten apps that turn a phone or tablet into a training monitor, compared on what decides whether they fit your course: where they run, how the devices connect, what they cost and how many rhythms they have.

Figures come from each maker's own website or the US App Store and Google Play listings, checked 25–26 September 2026. Prices and features change, so check the listing before you buy. "Not stated" means the maker's own listing doesn't say. Resus is the Android app by Quantingo; ResusMonitor is a separate web app. NAP was added on 7 November 2026, checked against its own website.
Where the Patient Simulator is different
The Patient Simulator runs in the browser, so there is nothing to install on either device, and it pairs over the internet with a six-digit code. The phone and the tablet can be on different networks, or in different buildings. TrainingMonitor.App, SimCore, ResusMonitor and SIMPL also connect over the internet, and the first three run in the browser too. SimMon, TruMonitor and Medical Rescue Sim connect over Bluetooth or Wi-Fi, which works best with both devices in the same room (TruMonitor also has a cloud mode).
The monitor never names the rhythm, and cardiac arrest behaves the way it does on a real monitor. PEA keeps a countable heart rate with no pressure or saturation, while VF and asystole blank the rate as well. A manual or scheduled NBP reading takes about fourteen seconds, like a real cuff.
It is free, with no account and no trial period.
Where the others go further
For the largest rhythm library, TrainingMonitor.App lists more than 200 ECG rhythms and 68 ready-made scenarios, also free and in the browser. If the course needs defibrillation, pacing or cardioversion on the monitor itself, look at TruMonitor or Medical Rescue Sim. Both list more ECG rhythms (40+ and 30), and TruMonitor also supports 12-lead ECG and CPR feedback with Laerdal manikins. NAP, a newer browser monitor that is free during its beta, lets learners defibrillate, cardiovert, pace and use an AED mode, and adds step-by-step scenarios and a recorded debrief. The Patient Simulator focuses on reading the monitor: vital signs, waveforms and rhythm recognition.

Frequently asked questions
How is the Patient Simulator different from SimMon?
SimMon is a paid app for iOS and Android (a one-time purchase) that connects the two devices over Bluetooth or peer-to-peer Wi-Fi. The Patient Simulator is free, runs in the browser with nothing to install, and connects over the internet with a six-digit code.
