Recently I found a website that allows you to make an iPhone web app that can be added on the homepage and have the look and feel of an ordinary app. With this service you are able to create an iphone app without a mac or sdk. With this service your apps are going to work with iOs and android
To continue you must have google chrome
Go to the link given below http://www.widgetbox.com/
Then register in this website by pressing the JOIN NOW button at the upper right of the website.Fill in the fields with your real email because you will need the incoming message from widgetbox that asks for validation.
Now you are ready to go.
