Free apps for Android & iOS: These Pro versions are currently free

This list is updated weekly with at least two weekly editions on Tuesday and Saturday. Between the publishing time and the time you read this article, some of the apps may have reverted to paid status. As to when Google Play Store promos for apps end are easy enough to predict, but it's more complicated with App Store promos since Apple doesn't specify just how long the discount is valid for.

Quick tip: You find an interesting app in the list, but you can't really use it right now? Install the app anyway, then delete it from your device. This way, the app will become part of your app library and you can install it again for free when you need it. A good way not to miss out on a short-lived promo.
