Make calcul in Figma

This will need to be implemented in the real app or in other tools. Figma doesn’t have any logic tools that allow you to dynamically change values in the prototype. You can prototype the app in Figma but it will not function like the real app.

Thanks! So I have to rebuild the entire app in another tool or once the app is finished in Figma I can migrate the project to another app?

Figma is not a development tool, even though you can put together some very advanced prototypes that may actually cover all the requirements of an application (first thing that comes to mind: tic-tac-toe).

In figma you can simulate a calculation by creating a series of frames you can animate to give the impression that it’s working, but that’s it.

For example you can create a calculator screen, add an interaction to the “2” button that will move you to a screen where you show the same calculator with “2” showing in the screen and an interaction on the “+” button to go to the next screen (and so on) but there’s no way you can actually script it.

The application itself will have to be developed, to give you a quick example, in a language like JavaScript and with an actual front-end.

Check out the Airfig plugin. It has the ability to populate and update Figma views with Airtable data.
