# Zef vs KiteRadar

The clearest difference is review sentiment: Zef at 91% against KiteRadar's 23%. Zef also leads on rating (4.6 vs 3.7) and ratings volume (41 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Zef sells 3 in-app purchases, starting at $6.99 per month and KiteRadar sells 8 in-app purchases, starting at $34.99 per year. Whichever you choose, the download price is not the number that matters.

Zef holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Zef has 41 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 91% of Zef's written reviews are positive against 23% of KiteRadar's.

Zef ships an update fortnightly, KiteRadar every 5 weeks. The most recent releases landed on September 26, 2026 and September 23, 2026 respectively.
