# True vs Tai Calendar

The clearest difference is in-app purchases: True at none against Tai Calendar's 3. True also leads on ads (none vs shown) and rating (4.7 vs 4.4). Tai Calendar's advantage is review sentiment (46% vs 18%). On price and device support there is nothing between them.

Both are free to download. Tai Calendar sells 3 in-app purchases, starting at $1.99 per month. True asks for nothing beyond the download.

True holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: True has 1.3K ratings behind it against 152, so its average is the more settled of the two. Written reviews complicate that: 18% of True's written reviews are positive against 46% of Tai Calendar's, so the app with the better star average is not the one people write more warmly about.

True ships an update every 11 days, Tai Calendar monthly. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
