Control who gets access to your apps.

By default, apps are visible only to you. Make your app private by adding users you want to give access to. You can make your app public too. Once you share your app with your team, it can be used both online and offline.

"Calcapp provides amazing support—no other product compares"
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.

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.
