No, we decided instead to create a web app that can be run on any device that has a browser.

You can, however, make the AWdb Web App look like an installed app by adding it to your Home Screen. Get details on how to do that for your particular device by searching the internet with something like "web app iphone home screen" or "web app android home screen". Once the app is added to your home screen, you will see the icon and be able to tap it like other installed apps.
