Companion Apps celebrating 40th Zelda anniversary
Today marks the 40th birthday of the great 'The Legend of Zelda' video game series. Over the last couple of years, we have built multiple companion apps for these games and many more will follow! Our small business started with a app for Zelda and is currently focused a lot around it - but we also cover other games and things by now. We try to enhance the expirence for everyone who wants to fully complete any of the games and gets as many information possible on the way. We always try to take ideas from the community into consideration to add them to our apps. As we are only two people doing this in our spare time, I personally find really neat what we did so far and I hope it already helped a lot of players out there. As our apps all work completly offline once installed, it may even be a good pick for regions with troublesome connection - and I personally see this as a good thing for a interactive map/checklist.
Due to the birthday event today, we like to share some free unlock codes for our apps.
It's dangerous to go alone, take this!

All codes can be redeemed within the app (last tab on the purchase page) or in the native app store of your device (you need to restore it afterwards in our app in that case). We used our own website for the code sharing as bot protection and to make it as fair as possible. That is also why we decided to release the codes in waves instead of all at once.
And on top of our apps, we also offer self made 3D printed merchandise for the Zelda franchise. And to celebrate the birthday event here as well, we have currently reduced every Zelda print in price and also share another discount code on top. The discount code is active for the first 50 orders with it and reduces the price by another 40%!
Our 3D print shop: https://shop.software-notion.de/collections/the-legend-of-zelda
Discount code: ZELDA40
I hope you all enjoy the franchise just as much as I do and I hope you can make good use of this little 'advertisement'. :)
