What useful mobile phone calendars have you seen?

Ink calendar is beautiful and easy to use. I started with the software style when I downloaded it. Few software can achieve such a Chinese style, which is also one of its highlights. Moreover, the ink calendar has many practical functions, from professional daily taboos, five elements of a day, washing evil spirits and paying attention to the spirit, to the fun test of leisure orientation, which can well meet everyone's different daily needs.
