Myfreeapps.org was created for both app users and developers. Users can discover new apps and even get paid apps for free.
In exchange for that, the user is requested to leave an unbiased review in the app store the the apps he downloaded. However, should be user be unsatisfied with the app, the first resort is always an e-mail to the developer, asking them to fix it before writing a nasty review in the app store.
App developers can distribute coupons, or promo codes for their paid apps. The developer will upload some (or all) of his promo codes to Myfreeapps.org
By clicking on "Get this app for free" the user who intends to get that app for free will be redirected to the app store and the promo code will automatically be applied.
A promo code is valid only one time. The next user needs another code. But you don't need to worry about that, Myfreeapp.org will take care about that under the hood
You just need to press that "Get this app for free" button and save a few bucks!
