PHONE Apps Web Apps
iphone, Android, Nokia, Palm
applications must be developed
separately.
Work on ALL smart phones! This
includes iphone, Android, Nokia,
Palm and others.
iphone, Android, Nokia, Palm
applications must be developed
separately.
Web applications have to be
updated once when there is an
enhancement.
Apps have to be submitted to
the App stores separately and
updates too be submitted
separately as well.
You never have to submit a web
application for approval to
separate App Store.
13. The Good
• Offer the most predictability for
development. You will always
know what size screens to design
for, and what the input
mechanism will be.
• By being included in app stores
you get access to a great targeted
marketing opportunity in a semi-
controlled marketplace.
• Your developers can be great at
one particular programming
language, rather than adequate at
many different languages.
• Work better when there is a slow
data connection because they rely
more on pre-loaded content
rather than content from the web.
The Bad
• Limited audience (only users of one
phone) OR you must develop multiple
apps, (one for each mobile OS).
• Can get expensive as it costs additional
money to submit your app to the various
app stores.
• There is a chance that the marketplace can
reject your app, and then you will have to
make updates.
• Updates must be resubmitted through the
app stores to be approved. This can really
add up in time and effort if you have
multiple phone apps and multiple updates.
• Crowded marketplace, frequently with bad
copycat apps, so it can be difficult to make
quality apps stand out.

14. The Web-based Apps
The Good
• Websites optimized for mobile phones
perform well on all types of mobile phones
that have Internet browsing capabilities.
• Web apps are easy to manage – you only
have to make updates once and they do not
have to be created, submitted, and approved
through multiple App Stores.
• More freedom and flexibility because App
Stores do not have to approve your
application.
• You won’t have to learn bunch of new
development languages.
• HTML 5 allows your web app to have
phone-like qualities like location awareness
and drag and drop.
The Bad
• Different mobile browsers work
differently so you will want to do testing
on several different phones and browsers.
• The rendering environment is very
unpredictable because there are so many
mobile browsers and screen sizes.
• Web apps will not be perfect all the
time – there are too many variables.
• There is very limited interaction with
phone stuff – like the shake feature on
the iPhone.
• You miss the opportunity for
representation and a presence in highly
visited app stores.

18. Apps are here to stay…..
62% of Indian mobile phone users
prefer Android based smart phones
Nielsen survey on a sample size of
10,000 consumers in September
and October 2012, across 46 cities
in India.
On average, smart phone owners
have 27 apps on their phones, up
from an average of 22 apps in
2009, and the typical Apple iPhone
owner has 41 apps (Nielsen poll of
more than 4,000 mobile
subscribers in 2010).
Women use online chatting
Apps 3 times more than
men whereas men install
16 Apps per month
compared to 11 by women
(Nilesen, March 2012 data)
Indian smart phone users are
in 18 to 29 years of age, more
active than their US
counterparts but number is 50
percent than US. (Google-
Ipsos-MMA Survey)
20. App Challenges
USERS
Proprietary (Apple, Windows)
OR Free (Google, Linux)
DEVELOPERS
Platform, screen sizes, hardware
specifications and configurations
MANUFACTURERS
OS with the best selection of Apps for making it
most attractive to consumers
