Powerful formulas

Connect Excel-like formulas—with support for close to 300 functions—to the fields of your calculator. 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 even be used to determine colors.

PDF reports, Excel, Slack and more

Collect information from your visitors with text and number fields, check boxes and sliders. At the press of a button, email PDF or CSV reports. Through Zapier and similar services, buttons can add collected data to spreadsheets, create Salesforce leads, post to Slack channels and more.

All the services you can use with Calcapp
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.

You get an app too

The same calculator you embed in your website can also be run as an app on iOS and Android. Once installed, your app appears on your users' home screens, complete with your logo and branded loading screen. Apps run offline.
