Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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