# まいスケジュール Lite vs Otona Calendar

The clearest difference is rating: Otona Calendar at 4.1 against まいスケジュール Lite's 1.0. Otona Calendar also leads on ratings volume (10 vs 1). まいスケジュール Lite's advantage is in-app purchases (none vs 1) and review sentiment (59% vs 42%). On price, update cadence, ads and iOS requirement there is nothing between them.

Both are free to download. Otona Calendar sells 1 one-off in-app purchase. まいスケジュール Lite asks for nothing beyond the download.

Otona Calendar holds the better App Store score, 4.1 against 1.0. That said, the two scores are not equally well evidenced: Otona Calendar has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 59% of まいスケジュール Lite's written reviews are positive against 42% of Otona Calendar's, so the app with the better star average is not the one people write more warmly about.

まいスケジュール Lite ships an update every 2 weeks, Otona Calendar fortnightly. The most recent releases landed on October 23, 2026 and November 1, 2026 respectively.
