# Solid Diary vs Clastly

The clearest difference is in-app purchases: Clastly at none against Solid Diary's 2. Clastly also leads on update cadence (fortnightly vs every 2 months) and review sentiment (100% vs 86%). Solid Diary's advantage is rating (5.0 vs 4.7) and ratings volume (26 vs 3). On price, ads and device support there is nothing between them.

Both are free to download. Solid Diary sells 2 one-off in-app purchases. Clastly asks for nothing beyond the download.

Solid Diary holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Solid Diary has 26 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 86% of Solid Diary's written reviews are positive against 100% of Clastly's, so the app with the better star average is not the one people write more warmly about.

Solid Diary ships an update every 2 months, Clastly fortnightly. The most recent releases landed on October 3, 2026 and October 6, 2026 respectively.
