-This intro-level tutorial walks through all the steps of building a basic progressive web app, or PWA. We will be using web technologies — HTML, CSS, and JavaScript — to build a period tracking web app called "CycleTracker". Like all web apps, CycleTracker is designed to work in all browsers on all devices.

-We will walk through the steps of building a fully functional web app, then progressively enhance CycleTracker to [make it installable](/en-US/docs/Web/Progressive_web_apps/Guides/Making_PWAs_installable) and to work even when the user is offline using a service worker.

 By default, PWAs are regular websites, built with the same technologies. Just like regular websites, PWAs are linkable, discoverable via search engines, and visible in a browser. By including a manifest file, and serving the website over TLS, any website can become a PWA.

 ## PWA benefits
 
 Using the languages of the web, we will create a fully functioning application that works both online and offline, both in the browsers and on the user's operating systems (OS). Like any regular website, CycleTracker is hosted on and downloadable from a web server. All we need is a text editor: CycleTracker, like all PWAs, doesn't require any additional programming language knowledge, packaging, or proprietary SDK. CycleTracker, like any PWA, can be seamlessly installed on any operating system without the need of app stores (nor app store approval and fees).
