The clearest difference is rating: 마루스캔 at 5.0 against illumeter's 4.6. 마루스캔 also leads on device support (3 vs 1) and iOS requirement (8.0 vs 16.0). illumeter's advantage is update cadence (every 2 weeks vs every 3 months) and review sentiment (100% vs 83%).

마루스캔 holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: illumeter has 12 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 83% of 마루스캔's written reviews are positive against 100% of illumeter's, so the app with the better star average is not the one people write more warmly about.
