Verdict
The clearest difference is rating: Aliens Motion Tracker at 4.7 against Asteroides's 2.0. Aliens Motion Tracker also leads on review sentiment (63% vs 33%) and ratings volume (290 vs 7). Asteroides's advantage is update cadence (every 5 days vs every 14 months) and iOS requirement (9.0 vs 12.0). On ads, in-app purchases and device support there is nothing between them.
