Interest in medical uses for Android platform surpasses iPhone

Introduction

Google Trends is a useful tool to monitor trends in keyword searches over time. In a previous post, I examined the growth of medical and healthcare apps keyword searches. The Apple iPhone started as the first dominant smartphone, but Android operating system smartphones are now growing in number and claiming an increasingly large share of the market.

In this post, I will look at medical search trends for specific devices including the iPhone and Android smartphones. The results may surprise you.

Methods

Google Trends is a free analytical tool that can be found under the more and then, even more tabs within the Google search page. In Google Trends, the relative number of Google searches by keyword are plotted on a graph. Actual numbers of searches are not given, but the highest number of searches in the data set is set to be 100. The remaining data points are normalized and statistically adjusted and plotted.

For this post, I started by adding two keywords, iPhone medical app and Android medical app to the Google Trends search box. Additionally, I selected the forecast button for this comparison post. I then added the term Windows medical app to the iPhone and Android medical app search. Finally, I looked at the Google Trends data for the search term iPad medical apps.

Results

The screen shot for the first comparison is shown below with iPhone medical plotted in blue and Android medical plotted in red. Several noteworthy findings can be seen in this comparison. First, iPhone medical clearly emerges as the earliest device with a nearly two year period before Android medical. Second, the iPhone medical keyword search peaked in early 2012. It is trending downward since that time. Third, Google Trends shows Android medical search terms recently equaling and then surpassing iPhone medical searches.

In the second screen shot, the Google Trends forecast function shows expected trends in searches for the next few months. The forecast lines for the next six months show a trend for increasing Android medical searches with a stagnant trend for iPhone medical searches.

In the third screen shot, Windows medical search finally appears on the radar in 2013, over four years after iPhone medical. The number of searches is relatively small in comparison to both iPhone and Android medical searches.

Like the iPhone, the iPad emerged as the early leader in tablets. In the final screen shot, iPad medical searches in 2010 shows a significant upward trend through 2011-2012. There appears, however, to be a decrease in iPad medical searches over the last year.

Interestingly, the regional distribution of trends by devices shows a predominance of iPhone medical search interest in the United States, Australia, Canada and the United Kingdom. In contrast, the highest regional trend for Android medical search comes from Pakistan, the Philippines and India.

Conclusion

This Google Trends analysis shows the relatively recent emergence of Android medical as an equal if not leading medical device in Google search. The take home message for app developers is to not ignore the Android operating system when planning and producing medical apps. Search interest in iPhone and iPad medical still remains high. Google Trends is a promising tool for continued monitoring of trends and geographic regional patterns in medical app device interest.
