PICULab

PICULab educational ventilator simulator brings hands-on ventilator learning to your iPhone and iPad. Adjust settings, change the patient and see the response in live waveforms, loops and measurements, breath by breath. Learn from every breath. The Learn panel explains in plain words what the current breaths show, and after each change it compares the breaths before and after. Turn on Label waves to name each part of the breath directly on the waveforms. Explore 13 ventilation modes across supported neonatal, pediatric and adult profiles, including pressure control, volume control, PRVC, SIMV, PSV/CPAP, APRV and noninvasive modes. Available modes follow the selected patient population. Open any setting to read what it does and how it changes the breath before you apply it. Start with normal lung mechanics, try the Asthma, PARDS and Circuit Leak teaching cases, or build your own patient from respiratory drive, lung mechanics and airway settings. Each case has its own targets: a reading that is off target turns red, and green once your settings meet it. The Guide explains every patient parameter, and the Tour walks you through the controls. When the patient breathes, the breaths they trigger change color on the waves and a dot marks each one. Practice inspiratory and expiratory holds and manual breaths, read the measured results and watch the lungs fill, hold and empty. Follow pressure-volume and flow-volume loops breath by breath. Pause to inspect the response, or reset to a clean normal baseline. Pinch to zoom and drag to explore the monitor, rotate your device and use flexible windows. All features are available for 24 hours from first launch. After that, a single in-app purchase unlocks lifetime access. No subscription or automatic charge. Restore an existing purchase with the same Apple Account. PICULab is an educational simulation, not a clinical ventilator or a tool for diagnosis, treatment decisions or patient-specific predictions. It is a simulation engine and does not reproduce all body dynamics or interactions between organs.

Verdict
The clearest difference is ads: PICULab at none against GRE Exam Practice's shown. GRE Exam Practice's advantage is iOS requirement (13.4 vs 17.0). On price, in-app purchases and device support there is nothing between them.
