Free Android and iOS Apps of the week

Normally, these are paid apps on Google Play and Apple App Store which will require you to fork up some cash, but from time to time, there are developers who decided to spread the love by making their apps available to the masses for free. This is what we do twice a week—scour the Google Play Store and Apple App Store to look for the best bargains. Grab them today on your Android or iPhone before they revert to paid status.

Note that while they're free as of publishing, these deals tend to expire without any due warning based on the developer's whims and fancy. The promotional period for apps on these platforms can be both unpredictable and can end suddenly.

You should know that we do have some form of quality control as we made sure that this list of free apps does not feature low-rating apps. However, we did not install and test them out like how we do with our Top 5 Apps of the Week. Therefore, we recommend that you exercise caution and conduct your own research before downloading any of these apps, as some may contain in-app purchases or hidden costs.

Tip: If you find an interesting app on our list but don't need it now, install and then delete it. This saves it to your app library, allowing you to install it later for free, even after the promotion ends.
