# Trello vs Google Calendar

The clearest difference is in-app purchases: Trello at none against Google Calendar's 32. Trello also leads on review sentiment (53% vs 35%). Google Calendar's advantage is ratings volume (132K vs 7K) and rating (4.5 vs 4.3). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. Google Calendar sells 22 in-app purchases, starting at $0.89 per month. Trello asks for nothing beyond the download.

Google Calendar holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Google Calendar has 132K ratings behind it against 7K, so its average is the more settled of the two. Written reviews complicate that: 53% of Trello's written reviews are positive against 35% of Google Calendar's, so the app with the better star average is not the one people write more warmly about.

Trello ships an update every 2 weeks, Google Calendar weekly. Both last shipped on September 24, 2026.
