SimMon is a basic remote controlled patient monitor for full scale medical simulation. Using SimMon on any pair of devices, iOS 13 or newer, gives you a simple remotely controlled simulated patient monitor. An iPad makes for an ideal multi-touch controlled remote and the big screen makes a great bedside patient monitor. Open SimMon on your two devices of choice and connect via WiFi or Bluetooth. Change the blood pressure, oxygen saturation, respiration rate or heart rate by touching the value and dragging your finger up or down. Simple setup. Easy operation. Low cost. Thank you for the amazing feedback and support - it keeps SimMon evolving!

When the ventilator alarms — what to look at, what to do. Vent Sim puts you at the bedside. The ventilator alarm is ringing: read the chart, use checks and treatments to find the cause and fix it, then name the cause and review what happened. Each scene takes about 2 minutes, and you can run them again on your own. Works on iPad and iPhone. It's also a full ventilator simulator underneath: - Modes: A/C-VC, A/C-PC, SIMV-VC, SIMV-PC, and PSV (with apnea backup ventilation) - Real-time airway pressure, flow, and volume waveforms that respond immediately to every setting you change - Alarms for airway pressure, tidal volume, minute ventilation, respiratory rate, and apnea - Work of breathing (WOB), so you can compare a patient's effort before and after a mode change - Built-in cases across normal lungs, ARDS (mild/moderate/severe), COPD, and severe asthma - A Sources screen showing where the app's numbers come from (textbooks, guidelines, papers), and marking which values are design decisions Free: A/C (volume and pressure control) and PSV modes, the core settings, 3 cases (normal lungs, moderate ARDS, COPD), and 2 training scenes (airway blocked by secretions, circuit disconnection). One-time purchase unlocks: SIMV (volume and pressure control), advanced settings (inspiratory pause, rise time), the remaining cases (mild and severe ARDS, severe asthma), 3 more training scenes (mainstem intubation, unplanned extubation, tension pneumothorax), and review export (image and data). One-time purchase — no subscription. Buy it once, use it for as long as you want. No accounts, no sign-in, and no data collection of any kind — see the Privacy Policy below. Please note: - This app is for education only and is not intended for clinical decision-making. - It is based on a single-compartment lung model and a simplified gas exchange model, so its behavior may differ from that of real patients. - It does not reproduce the behavior of any specific manufacturer's ventilator. When operating actual equipment, follow the manufacturer's instructions for use.

Verdict
The clearest difference is price: Vent Sim at Free against SimMon's $22.99. Vent Sim also leads on update cadence (every 5 days vs every 5 months). SimMon's advantage is in-app purchases (none vs 1) and chart position (#96 vs unranked). On ads, device support and iOS requirement there is nothing between them.
