Transcript of Location Based iPhone App Development
Built an iPhone Utility application from concept to an end product
for a company in North America
Sigma Infosolutions leveraged its
expertise on web based technologies
and iPhone SDK 3.0 to develop an
iPhone application along with its web
engine for a company in North
America.
The iPhone application now connects
its users to a comprehensive
database of utility service providers
across North America, based on the
type of service requested and the
nearest location of the user. Built on
GRAILS, the application extends
numerous customization capabilities
to both users and service providers.
The client is a funded technology product start-up with a vision to develop
iPhone applications that are meant to ease people’s lives. The client is based
in North America.
The ClientExecutive Summary
The client wanted to build an iPhone application, that will enable its business
users to connect with a comprehensive network of utility service providers
ranging from plumbers, carpenters, electricians, to many more across North
America. The iPhone application connects to a back-end web engine to
search for service providers by type of service, time, and location nearest or
preferred by the user. It will then notify the short-listed service providers
through e-mails and SMS. The service providers can then choose to get in
touch with the user either through e-mails or SMS.
The application will also allow users to bookmark favorite service providers
for future reference and also rate them on multiple parameters.
With this vision, the client approached Sigma Infosolutions to build this from
concept to an end product.
Business Case
ChallengesA robust end product was critical towards building a strong revenue channel.
Indian telecom service providers support limited features of an iPhone. This,
was becoming a major road block when testing the application on an iPhone.
Adding to this, many iPhone features that are critical for accurate
functioning of the application were not getting executed on iPhone
simulators.
Another major challenge faced by the team at Sigma Infosolutions was to
normalize all US time zones to ensure user request notifications reach the
service providers only during the time duration selected by them.
The application supports non-iPhone service providers, and they have an
option to send a reply back to the requesting party through e-mails. Since,
third party e-mail service providers attach their own headers to an e-mail,
this threw up another challenge at the team. The application had to be
designed to extract only the relevant information from e-mail replies, and
then pass it on the user's iPhone through Apple's push notification server.
Also, the team had to ensure timely delivery of notifications from service
providers to users and vice versa.
Obtained 100% accuracy in reverse geocoding

from their iPhone and also the web interface

other application users
