…iPhone statistics,
library services,
WorldCat mobile,
Android, Millennials,
charts and graphs,
yada, yada, yada…
Okay, we get it!
…now what?

build?
Hmm. Is it
too late to join
buy4lib?
e.g. iPhone app
written in Cocoa
requiring download
via the App Store
build
web app?
native app?
“Most of the folks I know in app
development are moving to
standardization on web versus
device specific development.”

This just out… an iPhone OPAC.
Download it from the App Store.
What? Uhhh. I just
bought a Nexus One.
Loser!
The Tao of mobile web (app) design
A mobile web app
should do one thing
and do it well.
A mobile web app should be as simple
as possible, but no simpler.




standards compliance
web usability design
minimalist design
design and testing

cross-browser
cross-platform

Simple is as
simple does.
iPhone web apps (according to Apple*)
* Content on iPhone: Is It a Webpage or an Application?

Three categories:



compatible with Safari on iPhone
optimized for Safari on iPhone
iPhone web application
W3C standards compliant
- no framesets or
- unsupported technologies
(cough, Flash)
If it doesn’t look exactly
like an iPhone app
it can’t be any good!

Gee, I love what
jQuery can do, but
maybe server-side
processing is the
way to go.

Generally come with handheld OS SDKs

Web-based simulators (be leery)

Opera Mini Simulator – good

Browser compatibility – don’t skip this
Internet Explorer
Firefox
Chrome
XHTML/HTML/CSS validation

XHTML/HTML
CSS
Accessibility
Get right with these
before you move on to
platform compatibility.
Mobile design – platform compatibility
viewport
Mobile design – platform compatibility
Larger buttons

Test it on the real thing (handset), too!
Just need to…
test… my app….
one… more time
Or, as a last resort…
Borrow from colleagues
Don’t forget the documentation!



Mobile/handheld developer sites have useful
information on how to “design for small”
Read it
Seriously. Read it.
A viewport?
Who knew?
It’s a small
world after all.
Example docs and websites

Reading?
I just want
to code!

Patrons can be persnickety.
Maybe I should practice on
the Library staff, first.
Hmmm, a staff app…
…easier to do a needs assessment
…easier to get UI feedback
…library has WiFi, so we can use
mobile devices without a data plan
What would help staff
working in the stacks?

Consider releasing
your mobile app as
free open source. It’s
better than free beer!

If that imbecile up
there can do it…
How hard
could it be?
Getting something
to beta would only
take me a week.
That’s it!
Any questions?
