Support

Nicutools is a clinical reference tool built by an Australian neonatal clinician for fellow NICU professionals. The website at nicutools.org is free; the iOS app is a one-time paid native-convenience layer with the same calculators.

How do I report an incorrect calculation?

Email [email protected] with:

• The calculator name.
• The exact inputs you entered.
• The result the app gave and the result you expected.
• The source you are comparing against (paper, protocol, textbook).

Can I suggest a new calculator?

Yes — email [email protected] with the reference paper or your local protocol. Calculators with a published peer-reviewed formula and clear clinical use case are considered for future releases.

Why does the iOS app cost money when the website is free?

The website stays free as a public-good resource for the NICU community. The iOS app is a paid native-convenience layer — Spotlight search, iPad split-view, haptic warnings, true offline operation, no analytics — for clinicians who want the phone-and-tablet experience at the bedside.

Does this work offline?

Yes, completely. Every calculator is a pure local function. The iOS app needs the network only to open the in-app Monitor Simulator tile (which loads a separate teaching tool); calculators themselves never make a network call.

Do you collect any patient data?

No. See privacy for the full description of what is stored locally on your device and what is never collected or transmitted.

Sources and citations

Every calculator’s Info, Algorithm, and References dialogs show the formulas in use and cite the primary published sources where applicable. A small number of calculators implement standard physiology textbook formulas without a single citable source and their References dialog says so.
