Monitors join with a 6-character code or a QR scan. No app, no account, no setup — a phone, tablet, or the ward TV becomes a patient monitor in seconds.

🫀

Life-like ECG

A real physiological engine — sum-of-Gaussians P-QRS-T, respiratory sinus arrhythmia, pulse deficit. Twelve rhythms that actually look like the textbook.

🔊

Real monitor audio

SpO₂-pitched pulse tones calibrated to published oximeter references — the beep rises and falls with saturation, exactly like the real thing. Mute is per-device.

📈

Smooth transitions

Deteriorate a patient over seconds or minutes with a single slider, or jump instantly. Rhythm changes land on the beat, never mid-QRS.

One-tap scenarios

Sepsis, hypoxia, STEMI, peri-arrest, VF, asystole — preset the whole patient in one tap, then fine-tune every vital with press-and-hold steppers.

Free, no accounts

No sign-up, no subscription, no per-seat licence. Built for sim educators who just want a monitor to work when the session starts.

Twelve rhythms. All physiologically real.

From sinus to torsades — generated, not looped. Fast rhythms are fast, blocks drop beats, AF is irregularly irregular, and VF means no pulse. Tap any rhythm to see it live.

Lead II Sinus · 75 bpm

Live in three taps.
