Free apps for Android & iOS: Get these paid versions for free!

This list of free apps will be updated twice every week. The usual caveat applies though: these apps are available for free at the time of publishing, but by the time you read this article or actually check out the listed apps, they might have reverted to their paid status. While Google Play Store promos on apps are relatively easy to look out for, things do get more complicated with the Apple App Store as promotions there is no particular time frame on when it will last, and can just disappear in the blink of an eye.

Quick tip: Whenever you come across an interesting app or game in our list but have no use for it just yet, or your device has simply way too much space, you can go ahead and install the app for now. Upon doing so, you can delete the newly installed app from your device as it would already have become part of your app library. This allows you to install it in the future as and when required. This is a reliable method to take full advantage of a short-lived promotion.
