There was a time when the main purpose of a cellular phone was to make calls. Now, mobile phones are used for so much more. They are used as daily planners, expense trackers, entertainment devices, and even flashlights, among others. Phones are more than just communication devices—they have integrated themselves into the daily lives of almost everyone on this earth.

And each smartphone runs on an operating system (OS). Without further ado, here are the top OSs of 2017 that you need to know about:

Android

The Android operating system is an open-source system that gives users a large amount of both control and flexibility. This allows developers to make all sorts of applications for Android users.

Because of its many features, the android is currently the top operating system in terms of number of units sold.

iOS

The iOS’s system, on the other hand, is more restricted in nature. Only applications developed or approved by Apple developers can be used on this platform. Which is why the Objective-C and Swift languages have become very popular.

While Android boasts of flexibility, the iOS system boasts of integration. Communication, document creation, and coordination become easier with Apple and iOS devices.

Windows Phone

The Windows Phone is by far the OS with the lowest market share. Even though it was developed in 2010, the Windows Phone has lagged behind its competitors.

This software is known for the movable and customizable tiles on its home screen. Even though seamless transitioning is still one of the issues, many businessmen prefer using Windows Phones.

Most, if not all, developers, know how to build applications for all three operating systems, but it is up to you, as the client, to tell them which one to build for first. Thus, it is imperative that you get a clear understanding about how each operating system works.
