DESIGNED FOR THE BEDSIDE

• Works offline — no data leaves your device, ever
• iPad-adaptive layout shows sidebar + calculator side by side

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.
