What are the free apps of the week? Find out here!

This list of free apps is updated twice-weekly. Of course, the usual caveat of the time of publishing and when you read this article applies. That time period might sometimes see some of the applications lose their free status. Google Play Store promos on apps are fairly easy to look out for, but things become more complicated where App Store promotions are concerned, as Apple doesn't specify just how long the discount is valid for.

Quick tip: Whenever you find an interesting app or game but do not need to use it just yet, you can install the app first. After doing so, delete it from your device as the app will already become part of your app library where you can install it again for free when required. This is a reliable method to take full advantage of a short-lived promotion.
