Special October Challenge

October was a special month for Windows Phone app (everything that is not a game) developers as the Special Challenge of October was announced precisely for them. All apps published through AdDuplex cross-promotion network during October that have at least 100 reviews and an average rating of 3.5* in the Store automatically got a chance to become a winner.

We promised that one of you will be able to chose the device he wants from Lumia 1520, Lumia 930 and HTC One (M8). So this time we congratulate Daniel Gjetsi and his app Antimosquito. Daniel picked the Lumia 930 as his prize. Nice choice!

Publish Your App Competition

Together with our Special Challenge winner we randomly choose two app and game developers and reward them with different Windows Phone devices every month. To become a part of this competition you only have to start promoting your app or game for free on AdDuplex cross-promotion network. So:

• Bogdan Bujdea and his app Fast Swipe won Nokia Lumia 730 (or $1000 AdDuplex advertising credit)
• Andreas Diermeier and his fun game Halloween Jewel will enjoy his new Nokia Lumia 530 (or $1000 AdDuplex advertising credit).

Congratulations to the winners! And of course more devices for developers prepared for November.

To become the winner of our Special November Challenge your game must comply with these simple requirements: it must have at least 100 reviews and average rating of 3.5* or more in the Store.

We are announcing Publish Your App Competition for the 9th month in a row already and it is aimed at getting yourself better acquainted with all of the WP devices. So this month we have prepared Lumia 630 and Lumia 635.

So it’s time for, I guess, the most cheerful post of the month where we announce the winners of our monthly challenge.

Our Special Challenge of September was a bit different from earlier ones as it was specifically tailored for developers. We promised to give away a high-end Windows Phone device to one of the developers who started promoting his app or game through AdDuplex cross-promotion network during September. The only conditions where that the app or game must have at least 100 reviews and average rating of 3.5* or more in the Store.

The Special Challenge was even more special because we let the winner to choose his prize from Lumia 1520, Lumia 930 and HTC One (M8).

This time the applauses go to Rune Selvåg for his app Piano Tunes which enable you to listen to beautiful piano tunes and even learn how to play them. Rune selected Nokia Lumia 930 as his prize. Congratulations!
