# Particle Detector vs SpyTracker

The clearest difference is review sentiment: Particle Detector at 100% against SpyTracker's 19%. Particle Detector also leads on in-app purchases (none vs 2) and iOS requirement (7.0 vs 13.4). SpyTracker's advantage is rating (4.5 vs 4.0) and ratings volume (808 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. SpyTracker sells 2 in-app purchases, starting at $7.99 per 7 days. Particle Detector asks for nothing beyond the download.

SpyTracker holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: SpyTracker has 808 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Particle Detector's written reviews are positive against 19% of SpyTracker's, so the app with the better star average is not the one people write more warmly about.

Particle Detector ships an update every 2 months, SpyTracker every 3 weeks. The most recent releases landed on June 7, 2026 and September 19, 2026 respectively.
