Improve patient care with calculator apps

Realize custom health care apps with Calcapp, including drug dosage, nutrition and administrative apps. Our no-code app builder requires no programming skills.

Ease of use

Apps present clear forms which are much easier to use than a spreadsheet grid in a high-stress environment

Fewer errors

Unlike spreadsheets, apps can't be accidentally tampered with and as a result produce fewer errors


Users can optionally be required to sign in, thereby ensuring that sensitive information is protected

Powerful formulas

Connect Excel-like formulas—with support for close to 300 functions—to the fields of your app. Formulas can also be used to determine if a field should be visible, what recipients a report should be sent to and whether a button should be grayed-out. They can also be used to flag possibly erroneous values.

No installation

Apps can run through any web browser, so they don't need to be installed by your IT department

Patient safety

Use validation to flag potentially invalid input or results, ensuring that errors are caught early

Calcapp has allowed us to easily create an app to score kidney injury risk in pre-operative patients (paper). It works both as an app and on the web, enabling its use both in a clinic and on the ward for elective and emergency patients. Customer support is excellent.

App plus web

A calculator can be embedded in a website, but also run as an app on iOS and Android. Once installed, your app is accessible from your users' home screens. Apps run offline.

We created Calcapp in 2003 to build apps for my neonatology department. One app calculates drug dosages and another calculates the optimal nutritional intake for newborn infants. Today, both apps have become indispensable.

Before deploying your app, be sure to test it thoroughly. Also, check with management to determine if the app needs to be certified before it can be used clinically.
