When the film starts, all you need to do is press “Play”, and the app automatically recognises the film sound. Don’t forget to take your favourite headphones! Of course, you can pause GRETA at any time, and when you carry on, the selected version always starts automatically at the correct point of the film. Sounds easy? It is easy! For multilingual versions: The app checks if the time of the show is correct and whether you are actually at the cinema. Please allow accurate localisation.

Verdict

The call

The clearest difference is rating: ARD Mediathek at 4.8 against Greta's 2.5. ARD Mediathek also leads on in-app purchases (none vs 5) and ratings volume (2K vs 6). Greta's advantage is iOS requirement (15.0 vs 17.0). On price, review sentiment, ads and monetization model there is nothing between them.

Both are free to download. Greta sells 5 one-off in-app purchases. ARD Mediathek asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

ARD Mediathek holds the better App Store score, 4.8 against 2.5. That said, the two scores are not equally well evidenced: ARD Mediathek has 2K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 49% of Greta's written reviews are positive against 41% of ARD Mediathek's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Greta ships an update every 2 months, ARD Mediathek every 3 weeks. Both last shipped on November 11, 2026.
