I typically think either we're designing for Tablets or Phones-- but not
for both at the same time. Most devs I've seen tend to develop 2 different
apps if they need to support both.
There is one good case for developing a single application that runs on
both the iPhone and the iPad. Universal apps rank higher on the search
results from the iTunes App Store.
Another reason is to have only one copy of the stack to update. I am
currently designing an app for any mobile device available: iPhone,
iPad, Android phone, Android tablet, anything.
Monte asked how we manage resolutions and screen sizes. The way I do it
is to ignore screen density and size and device type; I simply get the
working screenrect and use pixels. All objects and placement are
calculated by ratios. If a field needs to be a third of the size of the
screen, then I multiply the width and height by .3 and that's how many
pixels it is.
With this method I don't have to know anything about the device at all,
only the number of pixels available. I don't need to worry that it won't
fit some new device that comes out next week, and it doesn't matter what
OS is currently running. It works with Retina displays as well as tiny
2-inch phone screens. (I turn off the engine's auto-mapping for retina
displays.)
I don't use square cards, btw. I use a generically proportioned
rectangular card to get an idea of where objects should be placed, since
virtually all existing screens are rectangular. It helps me see how to
organize and proportion the layout in both portrait and landscape views.
Once I have a good layout for my generic screen rect, I calculate
proportions from that and apply them in resize handlers.
Now I'm keen to see what Chipp has done, I'm off to go look.
