# ZDF vs Greta

The clearest difference is rating: ZDF at 4.7 against Greta's 2.8. ZDF also leads on in-app purchases (none vs 5) and ratings volume (9.8K vs 5). Greta's advantage is iOS requirement (15.0 vs 17.0). On price, update cadence, ads and monetization model there is nothing between them.

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

ZDF holds the better App Store score, 4.7 against 2.8. That said, the two scores are not equally well evidenced: ZDF has 9.8K ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 66% of ZDF's written reviews are positive against 49% of Greta's.

ZDF ships an update monthly, Greta every 2 months. The most recent releases landed on September 27, 2026 and August 27, 2026 respectively.
