# Jカレンダー vs HachiCalendar

The clearest difference is rating: Jカレンダー at 4.9 against HachiCalendar's 3.0. Jカレンダー also leads on review sentiment (66% vs 30%) and ratings volume (27 vs 1). HachiCalendar's advantage is update cadence (every 2 weeks vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Jカレンダー sells 1 one-off in-app purchase and HachiCalendar sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Jカレンダー holds the better App Store score, 4.9 against 3.0. That said, the two scores are not equally well evidenced: Jカレンダー has 27 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 66% of Jカレンダー's written reviews are positive against 30% of HachiCalendar's.

Jカレンダー ships an update monthly, HachiCalendar every 2 weeks. The most recent releases landed on October 16, 2026 and October 17, 2026 respectively.
