# Calendars vs Solid Calendar

The clearest difference is ratings volume: Calendars at 122K against Solid Calendar's 119. Calendars also leads on monetization model (free with in-app purchases vs paid) and chart position (#103 vs unranked). Solid Calendar's advantage is review sentiment (79% vs 55%) and rating (4.9 vs 4.7). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Calendars sells 17 in-app purchases, starting at $3.99 per month and Solid Calendar sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Solid Calendar holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Calendars has 122K ratings behind it against 119, so its average is the more settled of the two. Written reviews point the same way: 55% of Calendars's written reviews are positive against 79% of Solid Calendar's.

Calendars ships an update every 11 days, Solid Calendar fortnightly. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
