Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
NICU Fluids
This medical calculator helps healthcare professionals quickly and accurately compute IV fluid rates, glucose infusion rates, and electrolyte levels for neonates. It's designed for nurses, students, and physicians caring for critically ill infants.
- GIR calculator (single or multiple drips)
- Electrolyte calculator (single or multiple drips)
- FENa calculator
- Accurate calculations for neonates
- Developed by a neonatal-perinatal fellow

NICU Fluids is a fast, clean set of calculators for clinicians managing intravenous fluids in neonates and children. Three tools, one tap apart. Electrolytes Enter the patient's weight, then add each drip with its dextrose, rate, NaCl, NaAcetate, and K. Results update as you type: GIR in mg/kg/min, total fluids in mL/kg/day, and sodium, chloride, acetate, and potassium in mEq/kg/day. Turn on calcium and magnesium for two more columns with gluconate and sulfate equivalents. Presets follow whichever field you're in, so NS, ½NS, ¼NS, and the acetate strengths are one tap away. Start with a single drip and add up to six. GIR A dedicated glucose infusion rate screen for when that's all you need. Up to eight drips, dextrose presets, and a solver that takes a target GIR and concentration and gives you the mL/hr, with the option to account for drips already running. FENa Enter serum and urine sodium and creatinine to get fractional excretion of sodium, with a plain-language interpretation. Switch between neonate and child/adult thresholds, since term neonates run higher at baseline, and see a reminder about diuretics and preterm variability. Also included -Results rounded to two decimal places, shown in blue so nothing reads as an abnormal flag -Light and dark themes, eight accent colors, fourteen font choices, and adjustable text size -No account, no ads, no data collection. Everything stays on your device. Formulas GIR (mg/kg/min) = Σ (% dextrose × mL/hr) ÷ (6 × weight in kg) Total fluids (mL/kg/day) = Σ mL/hr × 24 ÷ weight in kg Electrolyte (mEq/kg/day) = mEq/L × mL/hr × 24 ÷ 1000 ÷ weight in kg FENa (%) = (UNa × PCr) ÷ (PNa × UCr) × 100 NICU Fluids is a calculation aid for licensed healthcare professionals and does not replace clinical judgment, institutional protocols, or verification of orders.

This download is specifically for HealthStream customers who have purchased the STABLEize app for their employees. Requires a valid HealthStream login. The STABLEize app is a quick reference bedside tool for any staff taking care of well or sick infants. 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 review sentiment: NICU Fluids at 100% against STABLEize for HealthStream's 0%. NICU Fluids also leads on ratings volume (7 vs 2). STABLEize for HealthStream's advantage is rating (5.0 vs 4.3) and update cadence (every 2 months vs every 158 months). On price, 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
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
STABLEize for HealthStream holds the better App Store score, 5.0 against 4.3. Both are backed by a comparable volume of ratings — 7 and 2 respectively.
