I already bought Action Launcher 2: Pro – why do I have to pay again?
First, the good news: the app you previously bought, as well as all its previous functionality, is still available for you to use. This functionality resides in the Action Launcher 2: Pro app. If you want to use that version of Action Launcher, please feel free to do so.
As for why Action Launcher is a paid upgrade, the answer is simple: it is both a complete re-design and a complete re-write. By any measure, it is far, far more than a typical ‘update’, and contains a great number of key features (such as Quickbar, Quicktheme, customizable Gestures/triggers and a traditional All Apps page to name but a few) that were not present in Action Launcher 2.
I feel very happy with how many updates Action Launcher 2 received over the 2 years (11 major, >100 in total), and the value for money Action Launcher 2: Pro customers received for their $2-$4 purchase. Again, this purchase remains available to you, and you should use it as you see fit.
To sum up, charging for Action Launcher’s premium features helps ensure ongoing Action Launcher development remains a viable business proposition going forward. While there will no doubt be some Action Launcher 2: Pro customers who remain upset at this decision, given making it will result in a far higher quality app in the long run, it is a decision I hope most will be able to understand.
