# Aliens Motion Tracker vs Predator Viewer

The clearest difference is rating: Aliens Motion Tracker at 4.7 against Predator Viewer's 4.3. Aliens Motion Tracker also leads on chart position (#125 vs unranked) and ratings volume (290 vs 52). Predator Viewer's advantage is review sentiment (74% vs 63%) and iOS requirement (10.0 vs 12.0). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

Aliens Motion Tracker costs $0.99 and Predator Viewer $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Aliens Motion Tracker holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Aliens Motion Tracker has 290 ratings behind it against 52, so its average is the more settled of the two. Written reviews complicate that: 63% of Aliens Motion Tracker's written reviews are positive against 74% of Predator Viewer's, so the app with the better star average is not the one people write more warmly about.

Aliens Motion Tracker ships an update every 14 months, Predator Viewer every 12 months. The most recent releases landed on October 11, 2026 and October 12, 2026 respectively.
