NICU Fluids vs NICU Calculator
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.

NICU medical staff oversee the care of our most precious and delicate new citizens. It is a profession that requires precise calculations, and unfortunately those calculations could be subject to human error. With the NICU Calculator app, errors will be greatly reduced. This will help NICU medical professionals better serve their patients. The NICU Calculator will also speed up daily work rounds, allowing more time for critical cases and patient care. This calculator was made and designed with the support of NICU staff who perform these calculations daily. The NICU Calculator performs the following calculations: Fluid Calculator: Exact fluid management is important for infants in the NICU and we created a calculator to help calculate total fluid, TPN, intralipid, and feeding rates. It also helps calculate TPN components such as GIR, dextrose percent, percent amino acids, protein, and intralipids. Extra function also allows you to take other fluids patient is taking into account such as feeds, medication drips, blood products, and medication/flushes. Calorie Intake: Knowing how many calories you are providing to a premature or ill newborn infant is important in regards to their growth and overall well-being. We created a calculator that allows you to determine how many calories you are providing in the TPN and feeds given. Glucose Infusion: This calculator allows you to determine the individual and total fluid volumes and glucose infusion rates (GIR) given to an infant when they are on individual or multiple infusion drips. Ca/Phos Calculator: This calculator allows you to determine the amount of elemental calcium and phosphorus given to a patient when using calcium and phosphorus salts. It also helps convert between commonly used units and determines ionized calcium: phosphorus ratio needed to determine appropriate dose for daily intake. Gestational Age: Allows you to calculate corrected gestational age and days of life using date and gestation at birth. Umbilical line/ETT: Calculates umbilical catheter size, umbilical artery catheter length, umbilical venous catheter length, intubation tube size, and intubation tube length based on the weight of the baby.

Verdict
The clearest difference is price: NICU Fluids at Free against NICU Calculator's $2.99. NICU Fluids also leads on rating (4.3 vs 3.0) and review sentiment (100% vs 67%). NICU Calculator's advantage is update cadence (every 2 days vs every 158 months) and iOS requirement (6.1 vs 26.0). On ratings volume, ads, in-app purchases and device support there is nothing between them.
