SimMon vs STABLEize
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
SimMon
This app provides a remotely controlled simulated patient monitor for medical training. It allows users to adjust vital signs like blood pressure and heart rate on one device, displayed on another, facilitating realistic simulation scenarios.
- Remote patient monitoring simulation
- Adjustable vital signs (BP, SpO2, HR, RR)
- WiFi and Bluetooth connectivity
- Simple setup and operation
- Dual-device functionality

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!

In addition to The S.T.A.B.L.E. Program Module Guidelines: Sugar, Temperature, Airway, Blood pressure, Lab work, Emotional support for the family, this app includes a BONUS menu of 22 severe cardiac anomalies to increase understanding of how blood flows through the heart in the setting of ductal dependent and not ductal dependent congenital heart disease (CHD). - 4 calculators: corrected gestational age, temperature converter (Fahrenheit to Celsius and vice-versa), umbilical artery and venous catheter insertion depth, weight converter (grams to pounds/ounces and vice-versa). - Under Cardiac Anomalies you’ll find animations and information on 22 severe forms of congenital heart disease. The MP4 videos demonstrate how blood flows through the heart with the various forms of CHD, and for ductal-dependent lesions, the severe impact of ductal closure on blood flow. Other animations feature normal heart anatomy, hypercyanotic (tet) spell, and balloon atrial septostomy (Rashkind procedure). Also included are illustrations of palliative procedures (PDA stent, balloon valvuloplasty, BT shunt, RVOT stent, central shunt, pulmonary artery band). STABLE stands for the 6 assessment and care modules in the program: Sugar, Temperature, Airway, BP, Lab work, Emotional support. This app includes the following items: - Sugar module: General Guidelines for sick infants and infants at increased risk for hypoglycemia, IV treatment of a blood sugar less than 50 mg/dL (2.8 mmol/L), useful information about umbilical catheters and actions to correct umbilical artery catheter malpositions. - Temperature module: General Guidelines (hypothermic classifications, monitoring, rewarming after accidental hypothermia), and neuroprotective hypothermia checklist and neurologic exam. - Airway module: monitoring guidelines, respiratory distress descriptions, endotracheal tube sizes and insertion depth, blood gas evaluation, signs of a pneumothorax, and treatment of a pneumothorax. - Blood pressure module: assessment for shock and treatment of shock, including how to mix dopamine hydrochloride to constitute an 800 microgram/mL IV fluid solution. - Lab work module: risk factors for neonatal infection, clinical signs of infection, and laboratory evaluation prior to transport to an intensive care unit. How to calculate the absolute neutrophil count and immature to total ratio. - Emotional support for the family module: the various emotions that parents may be experiencing and how to help families who are experiencing the crisis of a sick newborn. The Cardiac Anomalies menu includes short descriptions and MP4 videos and illustrations for: - Normal Heart and Lungs - Aortic Valve Stenosis - Atrial septal defect - Atrioventricular canal - Coarctation of aorta - Double outlet right ventricle - Ebstein anomaly - Hypoplastic left heart syndrome - Interrupted aortic arch – type B - Patent ductus arteriosus - Pulmonary atresia with intact ventricular septum (IVS) - Pulmonary atresia with IVS and sinusoids - Pulmonary atresia with ventricular septal defect - Total anomalous pulmonary venous connection (TAPVC) – Cardiac, Supracardiac, Infracardiac) - Tetralogy of Fallot (moderate stenosis) - Tetralogy of Fallot (ductal dependent) - Transposition of the Great Arteries - Tricuspid atresia - Truncus arteriosus - Ventricular septal defect Includes illustrations of palliative procedures: balloon atrial septostomy (Rashkind procedure), PDA stent, balloon valvuloplasty, Blalock-Taussig (BT) shunt, right ventricular outflow tract (RVOT) stent, central shunt, pulmonary artery band.

Verdict
The clearest difference is rating: STABLEize at 4.9 against SimMon's 4.5. STABLEize also leads on review sentiment (100% vs 67%) and update cadence (every 3 weeks vs every 5 months). SimMon's advantage is price ($22.99 vs $24.99). On ratings volume, ads, in-app purchases and monetization model 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
SimMon costs $22.99 and STABLEize $24.99 up front. Neither carries in-app purchases, so what you see is what you pay.
STABLEize holds the better App Store score, 4.9 against 4.5. Both are backed by a comparable volume of ratings — 13 and 16 respectively. Written reviews point the same way: 67% of SimMon's written reviews are positive against 100% of STABLEize's.
SimMon ships an update every 5 months, STABLEize every 3 weeks. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
