Score Big Savings: Get Your Hands on Free Android & iOS Apps of the Week!

Please keep in mind that although these apps are free at the time of publication, they may revert to their paid status by the time you read this or try to download them. Unfortunately, there is no set timeframe for app promotions on the Google Play Store or Apple App Store, and deals can be removed just as quickly as they were added.

We also want to note that while we curate this list of free apps, we do not test them out like 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.

Here's a helpful tip: If you come across an app or game on our list that piques your interest but you don't need it right now, consider installing it and then deleting it from your device. This will save it to your app library, allowing you to install it again in the future when you need it. It's a great way to take full advantage of short-lived promotions.
