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

This list is updated weekly, with at least two editions - on Tuesday and Friday. Between the publication time and the moment you view this article, some of the apps may have already reverted to paid status. Google Play Store app promotions are pretty easy to predict, but it's more complicated with those on the Apple App Store, since Apple doesn't specify just how long the discount will remain valid.

• The best free Android apps you can get right now
• Best totally free Android games: no ads, no in-app purchases

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