  CLINICAL DECISION SUPPORT ONLY
  
  Nicutools is a reference tool for qualified healthcare professionals. All calculations must be independently verified against your local protocols and your patient's circumstances. Not a substitute for clinical judgement.

The free web version is at nicutools.org. This iOS app adds native iOS conveniences — Spotlight search, iPad split-view, haptics, true offline support, and no analytics.


## Version history (last 4 releases)

### 1.1.1 — 2026-08-19

Glucose Delivery: the Enteral figure in the result breakdown now includes any added carbohydrate, so IV + Enteral again matches the Total GIR shown above it. Calculations were always correct — this affected the breakdown display only.

### 1.1 — 2026-07-18

What's New in 1.1
 • New Resources section on the home screen.
 • Procedural Videos — quick access to demonstration videos (i-Gel, needle thoracentesis, Safe-T-Centesis).
 • External Links — one tap to trusted neonatal tools: sepsis risk, preterm growth charts, extubation success, outcome data, and BiliTool.
  Thanks for using Nicutools.

### 1.0.1 — 2026-07-11

What's New in 1.0.1 
  • ET Tube calculator: nasal (at-nares) insertion depth is now shown to the nearest millimetre for greater precision.
  • Clarified the nasal length formula in the Algorithm details.
  Thanks for using Nicutools — feedback is always welcome.

### 1.0 — 2026-07-08

No release notes.
