# Blue Moon App vs Solstice

The clearest difference is price: Solstice at Free against Blue Moon App's $0.99. Solstice also leads on rating (4.8 vs 4.0) and update cadence (every 2 months vs every 17 months). Blue Moon App's advantage is in-app purchases (none vs 3) and review sentiment (100% vs 85%). On ads there is nothing between them.

Solstice is free to download; Blue Moon App costs $0.99 up front. Solstice sells 3 one-off in-app purchases. Blue Moon App asks for nothing beyond the download.

Solstice holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Solstice has 82 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Blue Moon App's written reviews are positive against 85% of Solstice's, so the app with the better star average is not the one people write more warmly about.

Blue Moon App ships an update every 17 months, Solstice every 2 months. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
