This article aims to answer a very simple yet pertinent question: Which iPhone should a medical professional get.

With a wide variety of choice in terms of size and type, iMedicalApps would like to offer our insight into this choice from a physicians perspective. The amount of medical apps currently available for iPhones is astounding.

With so much choice available, one must seriously consider the choice of iPhone as it is important that it can fully complete the job it will be used for. The main criteria to judge by are hardware, software and cost.

The choices currently available in the Apple Store are listed below. I have omitted color options as these are little more than personal preference and do not affect core functionality.

  • iPhone 4S in 16GB, 32GB or 64GB
  • iPhone 4 8GB
  • iPhone 3GS 8GB


A note that the iPod Touch has similar functionality in terms of its ability to run iOS apps, however this article is purely focused on the iPhone.

The first major factor to consider is the hardware specification between the different iPhone generations. The iPhone 3GS has been a faithful servant, though, it has started to show its hardware limitations in the face of demanding applications and operating systems. The advent of iOS 5 (which is 2 generations higher than when it was first launched) has caused the 3GS slowdowns which has had a generally negative effect on usability.

The iPhone 4 is much more comparable to the flagship 4S in terms of hardware but crucially misses out on a higher resolution camera, advanced A5 processor and Siri. Furthermore, Apple is renowned for releasing a limited number of software updates to any particular model i.e. the 3GS will not be able to run iOS 6 even if it was capable of it.

When one considers these factors along with its limited 8GB size (more on that below), it is clear that any doctor looking to purchase an iPhone for use in day to day practice should only consider the 4S. There are a number of size options available and we shall take a closer look at the specific requirements of a doctor to further distinguish between these models.
