# Spy Detector vs E

The clearest difference is update cadence: E at every 4 days against Spy Detector's monthly. E also leads on rating (5.0 vs 4.8). Spy Detector's advantage is ratings volume (12 vs 2) and iOS requirement (14.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Spy Detector sells 3 in-app purchases, starting at $6.99 per 7 days and E sells 2 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

E holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Spy Detector has 12 ratings behind it against 2, so its average is the more settled of the two.

Spy Detector ships an update monthly, E every 4 days. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
