# Sectra vs LunaDay

The clearest difference is rating: LunaDay at 5.0 against Sectra's 4.5. Sectra's advantage is in-app purchases (none vs 1) and ratings volume (6 vs 1). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. LunaDay sells 1 one-off in-app purchase. Sectra asks for nothing beyond the download.

LunaDay holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Sectra has 6 ratings behind it against 1, so its average is the more settled of the two.
