Verdict
The clearest difference is price: Tracker Detector at Free against Sensors's $1.99. Tracker Detector also leads on rating (4.8 vs 2.0) and update cadence (monthly vs every 21 months). Sensors's advantage is in-app purchases (none vs 2) and device support (3 vs 1). On ads there is nothing between them.
