Build apps instead of spreadsheets

Forget error-prone Excel calculators and build apps instead. Imagine a cloud-based app designer enabling you to create apps without having to do any programming.

Ease of use

Apps present clear forms which are much easier to use than a spreadsheet grid

Works offline

Apps work offline, so that your users always have access

Confidential

Users can be required to sign in, thereby protecting sensitive information

Calcapp is simple enough for anyone to use and they provide amazing support—no other product compares. We quickly managed to bring our ROI marketing campaign to life with Calcapp. Using an outside developer would have cost $6,000.

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.

PDF reports, Excel, Slack and more

Collect information from your users with text and number fields, check boxes and sliders. At the press of a button, e-mail PDF or CSV reports. Through Zapier and similar services, buttons can add collected data to spreadsheets and databases, post to Slack channels and more.

We used traditional spreadsheets for many years to help our customers plan and operate water treatment systems using our products. Today, Calcapp has helped us move these calculations into an accessible mobile tool.

No installation

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

Rich text

Use lists, links, headings, different fonts and high-resolution images to liven up your documentation

Safety first

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

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.
