Previously, we introduced our project's concept and that is to create an app that enhances management of personal healthcare. Today, we will share with you the technical prospects and limitations revolving around our project.
Our preferred handheld device: iPad
According to royal.pingdom.com, Apples' iPad owns 88% of the global web traffic. Trailing behind are devices that run on operating systems like Android which accounts for 11% of the web traffic, webOS 0.5% and Blackberry OS 0.5%. In general, Joshua Toposky explains in engadget.com that the success of iPad's popularity and high web traffic can be attributed to the improvement on its sleek exterior design and efficient performance - shorter programme respond timing and easy to understand interface.
Ranking as the most favorable portable device over the years, it is no wonder that as of 02 March 2012, Apple's store has hit an astonishing six figures number of apps, of which 500,000 are iPhone apps and 140,000 more for the well - received iPad (adapted from www.apple.com - iPhone and iPad).
Hence, given Apple's pervasiveness in the market and the growing demand for iPad, we have decided to create our app which is compatible to the Apples' iPad.
