# Molekule vs Sunlighten

The clearest difference is rating: Molekule at 4.4 against Sunlighten's 2.8. Molekule also leads on ratings volume (11K vs 77) and update cadence (every 2 months vs every 4 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Molekule holds the better App Store score, 4.4 against 2.8. That said, the two scores are not equally well evidenced: Molekule has 11K ratings behind it against 77, so its average is the more settled of the two. Written reviews complicate that: 17% of Molekule's written reviews are positive against 19% of Sunlighten's, so the app with the better star average is not the one people write more warmly about.

Molekule ships an update every 2 months, Sunlighten every 4 months. The most recent releases landed on September 24, 2026 and September 7, 2026 respectively.
