# Ghost Detector vs K

The clearest difference is rating: Ghost Detector at 4.3 against K's 2.1. Ghost Detector also leads on review sentiment (60% vs 33%) and update cadence (fortnightly vs every 5 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Ghost Detector sells 6 in-app purchases, starting at $5.99 per 7 days and K sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Ghost Detector holds the better App Store score, 4.3 against 2.1. That said, the two scores are not equally well evidenced: Ghost Detector has 123 ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 60% of Ghost Detector's written reviews are positive against 33% of K's.

Ghost Detector ships an update fortnightly, K every 5 weeks. The most recent releases landed on October 28, 2026 and October 24, 2026 respectively.
