With 1776 Kanji you can create custom lists with your favourite Kanji. Your new lists are fully integrated with the preinstalled lists, you can learn custom and preinstalled lists together, and duplicates will be filtered automatically.
Alternative to our JLPT word lists there are also preinstalled Kyoiku-Joyo word lists for all school grades. There are separate lists for the Joyo Kanji added and for the Joyo Kanji dropped in 2010 so you can choose to learn following the old curriculum or the new one or both of them combined.
The Joyo Kanji word lists are strictly structured and every school grade word list contains all kanji from that grade, maybe combined with kanji from lower grades, but never kanji from a higher school grade.
