Verdict
The clearest difference is price: Ghost Detector at Free against Aliens Motion Tracker's $0.99. Ghost Detector also leads on update cadence (every 6 weeks vs every 14 months) and ratings volume (6.1K vs 291). Aliens Motion Tracker's advantage is in-app purchases (none vs 10) and ads (none vs shown). On rating, review sentiment and device support there is nothing between them.

Ghost Detector is free to download; Aliens Motion Tracker costs $0.99 up front. Ghost Detector sells 10 in-app purchases, starting at $0.99 per 7 days. Aliens Motion Tracker asks for nothing beyond the download.
Aliens Motion Tracker holds the better App Store score, 4.7 against 4.5.

Written reviews complicate that: 63% of Aliens Motion Tracker's written reviews are positive against 64% of Ghost Detector's, so the app with the better star average is not the one people write more warmly about.
