Verdict
The clearest difference is price: OpenD6 Toolkit at Free against Alien Motion Detector's $1.99. OpenD6 Toolkit also leads on rating (5.0 vs 3.9) and update cadence (every 6 days vs every 6 weeks). Alien Motion Detector's advantage is ratings volume (31 vs 1) and iOS requirement (10.0 vs 12.4). On ads, in-app purchases, monetization model and device support there is nothing between them.
