Grilometr – PWA Calculator for Grill Owners
A micro-site for gas grill owners. The user enters four values – the cylinder tare weight, its current weight, the number of grill burners and the output of a single burner – and Grilometr calculates how much grilling time is left in the cylinder. Depending on the result, one of three colour variants is shown.
Built as a PWA in plain HTML, CSS and JavaScript, without a framework. A service worker keeps it working offline and it can be installed on a phone home screen with its own icon. The design targets portrait mobile first. The client’s designer supplied the artwork. Delivered for Primagas in cooperation with the Prague Culinary Institute (PRAKUL).
