Install SolutionLab as an app

Installing adds a shortcut that opens SolutionLab in its own window. It still needs an internet connection to load, and your entries stay on your device. Not every browser offers installation.

Chrome or Edge on a computer: use the install icon in the address bar, or open the browser menu and choose Install.
Chrome on Android: open the menu and choose Install app (or Add to Home screen).
Safari on iPhone or iPad: tap Share, then Add to Home Screen. Safari on a Mac: File, then Add to Dock.
Firefox on a computer: installation is not supported; the calculator works normally in a tab.
