Medical Simulation on the iPhone and iPad. Excellent learning tool for doctors, medical students, nurses and paramedics/EMS. Undertake realistic medical simulation training without the need for expensive/high-fidelity mannequins. Perfect revision aid for life support courses, OSCE exam preparation or ad hoc teaching. Verbally create a scenario as simple or as complex as the teacher wishes. If the student has a 2nd device, connect via Bluetooth or Wi-Fi and the 2nd device becomes a realistic monitor. If the student initiates appropriate management for the simulated patient, the teacher can improve the patient’s vital signs. If not... the patient can deteriorate and eventually suffer cardiac arrest. The teacher can alter multiple patient parameters as the scenario evolves: - ECG - BP - Arterial Line - SpO2 - Resp Rate - Temperature - Fingerprick Glucose - Capnography (once intubated) - End-Tidal CO2 - Lab results - Haematology/Biochemistry/Blood gases Change ECG rhythms instantly or via defibrillation/CPR cycle. Choose from an extensive list of ECG rhythms (In App Purchase required to access advanced waveforms) •Normal Sinus Rhythm •VF •VT •Asystole •Various AV conduction defects •AF •AF with digoxin effect •Torsades de Pointes •Atrial Flutter •Flutter Pause •Bigeminy •Electrical Alternans •Mild / Severe hyperkalaemia •Junctional Escape •Long QT •Multiple Ectopics •Pacemaker with and without capture •Pre-Excited AF •ST elevation / depression •SVT •Wolf Parkinson White Once intubated, multiple capnography options are available (In App Purchase Required to access advanced waveforms) •Normal Breathing •Rebreathing •Obstructive Breathing •Apnoea •Breathing System Disconnection •Malignant Hyperpyrexia •Inadequate Paralysis •Acute Loss of Cardiac Output

The Arterial Blood Gas Interpreter is intended to assist medics with interpreting blood gas results. It calculates the delta ratio and anion gap and offers possible differential diagnoses based on the results. In addition, it contains useful tips and explanations to help healthcare professionals understand how blood gas results are interpreted. The ABG interpreter also validates the user's input when interpreting blood gas results to ensure that only valid parameters are inputted. This intuitive nature reduces the chances of erroneous interpretations. In this update, there is a brand new quiz section where users can test their ABG interpretation skills and practice for exams. Disclaimer: This tool is provided for educational and informational purposes only. While I hope you find it useful to you as a healthcare professional, it is in no way intended to serve as a diagnostic service or platform, to provide certainty with respect to a diagnosis, or to otherwise substitute for the clinical judgment of a qualified healthcare professional.

Verdict
The clearest difference is review sentiment: ABG interpreter at 100% against TruMonitor's 34%. ABG interpreter also leads on monetization model (free vs free with in-app purchases) and iOS requirement (13.0 vs 15). TruMonitor's advantage is rating (3.7 vs 3.0) and update cadence (monthly vs every 19 months). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
TruMonitor holds the better App Store score, 3.7 against 3.0. That said, the two scores are not equally well evidenced: TruMonitor has 49 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 34% of TruMonitor's written reviews are positive against 100% of ABG interpreter's, so the app with the better star average is not the one people write more warmly about.
TruMonitor ships an update monthly, ABG interpreter every 19 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
