New djay 2: do I need to pay again?

Hi, I just want to download your new djay 2 app. A couple of days ago, I deleted djay from mi ipad (i was running out of disk space). Now I’m not sure if this is just an update or what, because in AppleStore I need to pay 4,99€ to download it… Any ideas?

It looks like it, I paid 19.99 for the first one now need to pay again.

First off, we’d like you to know how grateful we are for our loyal fans. It is your ongoing feedback and support that keeps us motivated to deliver the best djay app in the market. 
Since the first release of djay for iPad in Dec. 2010, we’ve delivered 18 FREE updates over the past 2.5 years, winning the Apple Design Award (2011) along the way. We’ve always listened to your requests, incorporated the most popular wishes and the positive feedback we’ve received was almost enough as payment for all the hard work. We say almost, because as a company, we have to look for our revenue every now and then. As much as we enjoy working on our apps, we have to charge an upgrade fee at some point, if we want to continue doing so. We hope you understand.
Please also note that there is no way for us to distinguish between new and existing customers in the App Store. We can only set one price for everyone.
With djay 2, we’re proud to present you the result of almost 2 years of development. Not only do we give you a whole new app with entirely new capabilities (e.g. Colored Waveforms, Waveform Mode and Sampler), we’ve also completely redesigned the library, packed with very useful features like Instant Preview. That being said, we believe that an upgrade price of 4.99$ (or 0.99$ for iPhone) is really fair. Please also take a moment and watch the overview video of djay 2: https://www.youtube.com/watch?v=sJ0MipTwMQU&feature=player_embedded
The video walks you through all new features in djay 2 and will show you that this is really a whole new app and not just an update.
Again, thank you very much for your loyalty and support. We’ve put our hearts and hard work into djay 2 and it just blows our mind. We hope you feel the same.

… and the first one wasn’t as good as it should be. This is a new way to sell the same shit one more time, if you ask me. It may be better, but I dont know.
