# Detector vs Zerk

The clearest difference is ads: Zerk at none against Detector's shown. Zerk also leads on rating (5.0 vs 4.6) and monetization model (free vs ad-supported). Detector's advantage is ratings volume (557 vs 1) and update cadence (every 10 days vs monthly). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Zerk holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Detector has 557 ratings behind it against 1, so its average is the more settled of the two.

Detector ships an update every 10 days, Zerk monthly. The most recent releases landed on October 26, 2026 and October 16, 2026 respectively.
