I want to create a mobile web app which can be used on any device like smartphone or tablet. I need UI design suggestions for designing the user interface in a such way that it fits well in phone and as well as tablet.
The app basically allows the user to report a damage about his property to the insurance company. The user can report the damage by uploading the pic of the property that is damage or by manually enter the details of the property and damage details. Once the user uploads the pic the app shows up the gMap wit the list of properties in the near location of the area where pic is taken and uploaded based on the geotag of the pic. after the user selects the property by tap of the marker on map. a form should get dislayed to enter required details and submit.
Please give me your suggestions to design this kind of app which fits well to any device .
