# Udf Editör vs Zetlog

The clearest difference is rating: Zetlog at 2.9 against Udf Editör's 2.3. Zetlog also leads on monetization model (free with in-app purchases vs subscription) and update cadence (every 3 weeks vs every 6 months). Udf Editör's advantage is iOS requirement (11.0 vs 17.4). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Udf Editör sells 2 in-app purchases, starting at $3.99 per month and Zetlog sells 8 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Zetlog holds the better App Store score, 2.9 against 2.3. That said, the two scores are not equally well evidenced: Zetlog has 16 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 19% of Udf Editör's written reviews are positive against 15% of Zetlog's, so the app with the better star average is not the one people write more warmly about.

Udf Editör ships an update every 6 months, Zetlog every 3 weeks. The most recent releases landed on October 21, 2026 and October 30, 2026 respectively.
