"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.
Calcapp is very powerful and has been solid and reliable the whole time we've used it. We have been able to create everything we have wanted to. Finally, a great way to make web calculators!

Yes. When you create an account, a 30-day free trial period is started. You have unlimited access to Calcapp during this period. To ensure that your shared apps continue working after the trial period, be sure to sign up for a paid plan before the trial's end date.
Yes. Our Free plan allows unlimited access to Calcapp Creator, our app designer, and Calcapp Connect, which allows app creators to run their own apps. As such, personal apps can be run on the Free plan. However, in order for others to run your apps, you need a paid plan.
If you go over the plan limits and you're on a paid plan, your app will continue working normally. We will, however, reach out and ask you to upgrade to a more capable plan. Apps on the Free plan stop working when you hit the plan limits and only resume working once a new month rolls around.
A public app is accessible to anyone with a link to it — use a private apps instead if the app contains sensitive information. With public apps, you pay per app.
Private apps require your users to sign in before gaining access to your app. They all share the same private plan. With private apps, you pay per user and can use an unlimited number of apps.
Embedded apps are meant to be part of your website and cannot run as standalone apps. They all share the same embedded plan. The number of apps that can be put on the same plan varies depending on what plan you choose. Private and public apps can also be embedded, but the embedded plan is more cost-effective for sites with many apps.
