A web app with Touch UI displays a small logo on the left side of the tool bar next to the Home button. The logo is also displayed in the same spot on tablets and desktop devices.The color of the logo depends on the user interface theme. A separate “icon” logo is displayed by mobile devices on the home screen if a web app has been installed to run in a full screen mode.

The screenshot shows a standard colorful logo of a web app displayed on full screen of iPod Touch.

Next screenshot shows a black logo in a web app displayed on full screen of iPad Air.

This screenshot shows an application with Touch UI on a desktop computer. The logo is white.

This is an icon of installed web app as displayed by iPad Air.

The standard logo files can be found in the ~/touch folder of Web Site Factory and Mobile Factory applications.

The same files are found in ~/WebApp/touch folder of Web App Factory projects.

Azure Factory applications keep the logo files in ~/WebRole1/touch folder.

Replace the files with your own images for a customized look.

Create logo-black.png, logo-color.png, and logo-white.png images with the size 120 x 54 and copy them over the standard files to replace the logo on the toolbar.

Create logo-icon.png with the size 196 x 196 and replace the corresponding file for a custom application icon.

Here is an example of a custom logo that we are using to modify the standard toolbar images. Our file has a transparent background. We have used exactly the same image for all three logos displayed on the toolbar.

This is how the new logo looks in a live application.

If the the standard size of the logo is tool small, then consider creating a custom CSS stylesheet in the ~/touch folder and placing a CSS rule that will replace the standard positioning and sizing of the logo.

Custom file StyleSheet.css is placed in the touch folder of a Mobile Factory app in this screen shot.

This is the rule that changes the position of the background and its size. We recommend experimenting with actual values to accomplish the best fit for you needs.

@media (min-width: 20em) {
    .ui-header.ui-header-fixed:not(.app-tabs) {
        background-position:1.75em 0;
        background-size:100px;
    }
}

The logo in the next screen shot takes the entire height of the toolbar.

The larger file logo-icon.png provides a custom application icon on a home screen of iOS device.

Web Apps created with Code On Time have a fluid, native-like performance on both desktop and mobile devices. Mobile end users are accessing web apps through a web browser integrated into operating system of their device. Modern mobile browsers allow adding a web app shortcut to home screen of the device. If a web app is started from home screen, then the browser will hide the address bar and navigation controls taking advantage of the entire real estate of the screen.

Compare the screen shots of a web app created with Code On Time displayed on iPhone 5. Both screen shots show exactly the same web app. The former was started from the home screen of the phone. The latter was started directly in mobile Safari. Web app “installed” to home screen clearly provides access to more information and has a “native” look and feel. A thin black bar at the top of the screen provides a user with vital device status information when interacting with “installed” web app.

The same benefits are obvious if device orientation is changed to landscape.

It is very easy to install a web app to home screen of a mobile operating system.

Consider the process of installing a web app created with Code On Time on iPad Air.

First, open mobile Safari and navigate to http://demo.codeontime.com.

Tap “Share” button and select “Add to Home Screen” option in the popup window.

Change the name of the link as needed and tap “Add”.

An icon with a chosen title will be added to the home screen. This concludes the installation process.

Note that it is easy to provide a custom application icon and logo for a web app created with Code On Time.

Start your web app to enjoy the full screen experience on iPad Air.

Here is the installation process for Google Nexus 7.

Enter the address of the web app created with Code On Time and tap “menu” button on the browser toolbar. Select “Add to homescreen” option, change the title as necessary, and tap “Add” .

The web app is now installed.

Tap the icon to access the web app for a full screen experience.

Web apps created with Code On Time allow changing various settings such as theme and page transition effects. Note that those settings will not be inherited by installed app. Web apps added to home screen maintain their own settings on the device.
