What are Web Apps?

Web apps are applications running in the web browser of your device. They are using standard web technologies like JavaScript, CSS3 and HTML5. New application interfaces implemented along with HTML5 enable new features for web apps like:

  • store data on your device (Data Storage)
  • run without internet connection (Application Caching)
  • identify device location after user confirmation (Geolocation API)

For more information please see the following resources:

The web apps on this site are free of charge and provided 'as is', without warranty of any kind (see Terms of Use). They contain no adds. I have mainly created them for my own purpose or just to become familiar with new technologies.

How to run Web Apps?

Web apps are just loaded like normal web sites. Just enter the web address (URL) of the web app in your web browser. For restart just bookmark the web app. You can also add an application shortcut icon to your home screen:

Home screen icon on iPhone/iPad/iPod

  • Tap the bookmark symbol of the browser.
  • Choose 'Add to Home screen' to create an icon on your home screen.

Home screen icon on Android devices
(see also https://developer.chrome.com/multidevice/android/installtohomescreen)

  • In the general browser menue or when creating a bookmark you can usually select an option 'Add to Home screen'.
    If not, please try this:
  • Bookmark the web app and open the bookmark menue.
  • Press and hold your finger on the bookmark you have just created.
  • Select 'Add to Home screen' to create an icon on your home screen*.
    (On older devices this can be: 'Add shortcut to Home')

Start screen tile on Windows Phone

  • Tap the lower ... symbol.
  • Choose 'pin to start' to add the web app as a tile to your start screen.
