Verdict
The clearest difference is rating: Merge Explorer at 4.1 against AR Orbitals's 2.8. Merge Explorer also leads on review sentiment (46% vs 17%) and ratings volume (279 vs 8). AR Orbitals's advantage is in-app purchases (none vs 4) and iOS requirement (11.0 vs 15.0). On price, ads and device support there is nothing between them.
