As well as popping some lyrics on her Twitter earlier, Lady Gaga's also been on a bit of a Twitter spree, clearing up any confusion around the whole 'ARTPOP' app thing.
The app will be available globally on iTunes and Google Play and will be free to download.
"The ARTPOP app is Free, available in App Stores on your device. You can purchase the music through the ARTPOP app once it's downloaded," she explained.
"Or you can purchase the album at the music store+download the free app separately at the app store. ‑GAGA".
She then added helpfully: "The APP is in essence, an interactive jewel case. ‑GAGA".
Oh and also the video for 'Applause' will 'premiere' on the same day it comes out, which is August 19.
