On a tight budget? Get these paid apps for free!

This list of free apps is updated weekly with at least two weekly editions. Between the time of publication and the moment you read this article, it is possible that some applications have become paid again. Google Play Store promos on apps are fairly easy 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: Whenever you stumble upon an interesting app but have no real use for it just yet, why not just install the app? After doing so, just 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. This is a justifiably reliable method to take full advantage of a short-lived promotion.
