"Gengou Free" is a quick reference of the Japanese era system. This application has functions as below. - Era and Year Search - Period picker - Era picker - Christian era year picker - Japanese era year picker - Show this year button - Texts can be shown in Japanese or English independently of the default language setting. - Application badge can show this year number in the Japanese era or the Christian era. The Japanese era system identifies a year by the combination of the era name (Gengou or Nengou) and the year number within the era. For example, A.D. 2001 is Heisei 13. Please note that two Gengou schemes were used in Parallel from 1331 to 1392 during Nanboku-chō period. This application would be very useful if you are working with the governments, municipal offices and/or certain companies in Japan.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
To Do holds the better App Store score, 3.6 against 2.5. That said, the two scores are not equally well evidenced: To Do has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 66% of To Do's written reviews are positive against 84% of Gengou Free's, so the app with the better star average is not the one people write more warmly about.
To Do ships an update every 6 months, Gengou Free every 44 months. Both last shipped on October 31, 2026.
