# Modulin vs LH Grey

The clearest difference is rating: LH Grey at 5.0 against Modulin's 4.3. LH Grey also leads on in-app purchases (none vs 1). Modulin's advantage is ratings volume (17 vs 2) and iOS requirement (10.0 vs 13.0). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Modulin sells 1 one-off in-app purchase. LH Grey asks for nothing beyond the download.

LH Grey holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Modulin has 17 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 69% of Modulin's written reviews are positive against 67% of LH Grey's, so the app with the better star average is not the one people write more warmly about.
