We have over 250,000 apps in the app store.We don’t need any more

LIFE ONTHE APP STORE
• Most mobile applications have
a relatively short “shelf life”
with on average less than
25% of users returning to the
app one day after download,
dropping to around 5% after
30 days.

LIFE ONTHE APP STORE
• Most mobile applications have
a relatively short “shelf life”
with on average less than
25% of users returning to the
app one day after download,
dropping to around 5% after
30 days.
• Pinch Media
The category to which an application
belongs seems to have a strong
effect on return rate – applications
that are typically more dynamic e.g.
sports (results, league tables etc.)
and entertainment apps fared better
than games, utility, and lifestyle
applications.
SHUFFLINGTHE DECK
• By appearing on the Top 100
list, applications would receive
2.3x more downloads on
average and often an order of
magnitude higher for the Top
25 and Top 10 list.
• Pinch Media
DOING A DEAL
• ”We only did the first iPad/
iPhone integration with
Chillingo and aside from that
we’ve published everything
ourselves.We will not use
Chillingo again.”
• “You don’t need publishers.

UX CONCEPTING
The concept can describe an existing or non-existing product
DEVILS INTHE DETAIL
• The level of detail of the concept
description detail can vary.This
depends on
• The target audience you are
trying to impress :Investors /
management / engineers /
consumers / etc.
• The next product decisions to
make (management or
development)
DESIGN APPS AS
INFORMATION APPLIANCES
• Design Axioms for an
Information Appliance:
• Simplicity
• Versatility

are intertwined

IMPACT OF GRAPHICAL
DESIGN
IMPACT OF GRAPHICAL
DESIGN
You form your
first impression in
a few seconds
(mostly
subconscious
activity)
Graphical Design impacts
users emotionally, even
before they start thinking
First impressions
are important in
relationships
In this case, the
“user-product”
relationships
You might change
your choice after
looking at the
designs for a
while (conscious)
Limited display space
requires tough
prioritization on what
to present, and how
Some desktop
designs are directly
applicable, others
completely
unacceptable
REINVENTING
THE WHEEL
The universal graphical design
rules apply also for mobile
device UIs
However consider carefully
what metaphors or other
design details can and should be
adopted from the desktop
designs
COLOUR
Colour is a wide topic. It can cover
aspects of science, art and
psychology
Wireframes are often black-and-
white by purpose
Colors can steal the attention
from the interaction design
A rule for mobile devices - keep it
simple
PICKING COLOURS
When selecting colours some designers rely on their personal
experience, intuition and taste
CHECK IN CONTEXT
MAYTHE FORCE OF
TYPOGRAPHY BE WITHYOU
You might take typography for granted until it fails.
What	
  was	
  normal	
  for	
  typewriting	
  in	
  the	
  past,	
  
looks	
  now	
  outdated.
Of	
  course	
  if	
  your	
  UX	
  is	
  to	
  look	
  old-­‐fashioned,	
  
it	
  can	
  provide	
  the	
  effect	
  your	
  looking	
  for.
There are many way to ruin a reading experience
The text might look cool, but it can be hard to read
Graphical Design is not the opposite to text, it is a part of it
Typefaces alone can have an both emotional and
practical impacts on the reader.
SIZE NOW
MATTERS
For three generations of the
iPhone,Apple kept the screen
consistent (320x480 pixels and 3.5
inches diagonal). But now Apple's
new iPhone 4 boasts the highest
resolution phone screen ever
(960x640 pixels, 3.5 inches
diagonal, & an 800:1 contrast ratio.

UTILITY IN MOBILE DEVICES
If utility is important to the mobile application concept the
graphical design should be Simple, clear and effective
Use colours and
layout to create
clear and logical
structures for the
content.
If you use images,
minimise the size.
Avoid decorative
elements.
Avoid horizontal scrolling
CHECKLIST
• Check the desired company/product brand
• Check what are the UX goals: will “standard” design be enough or
is a “wow” desired
• You can break the graphical design rules - but only if you know
them
• Check the target mobile UI platform: look, feel and components
• Validate product concept, use cases, UX requirements
• Do close cooperation with interaction design
• Check the display technology where the application will be used
