Needs & Feeding

Dietitian calc: needs, BMI/TPN

Free · In-App Purchases · Designed for iPad. Not verified for macOS.

Needs assessment, amputation-adjusted BMI, and a full EN/TPN calculator — one-time purchase, works offline, built for registered dietitians. Needs & Feeding is a clinical calculation suite built for registered dietitians and nutrition support clinicians — three tools in one clean, offline-ready app. NEEDS ASSESSMENT Ideal body weight (Hamwi), %IBW, %UBW, weight-change significance, BMI, and calorie/protein/fluid needs calculated across multiple validated equations (Mifflin-St Jeor, Harris-Benedict, Penn State 2010b, and more) side by side. AMPUTATION-ADJUSTED BMI Select the amputation level per limb and get an adjusted BMI that reflects the patient accurately, instead of one skewed by missing body weight — sourced to Osterkamp (1995). EN / TPN CALCULATOR A 21-formula enteral nutrition reference list plus continuous feed, bolus feed, and TPN calculators — GIR, macros, free water, and electrolyte additives, calculated live as you type. Every formula is cited in-app, so you always know exactly where a number came from. One-time purchase, no subscription, no account required. Install it on your phone like a real app — it works offline once installed, and your license key unlocks it for good. Built for licensed healthcare professionals as a reference and documentation aid — not a substitute for clinical judgment, facility protocol, or pharmacist verification.
