content: I can say ticktick is the best to do list because a lot of feature like Eisenhower list habit tracker etc. But the it have very very bad part. You cant fully syn it with other platforms. Probably the developers want you to do everything on ticktick but its not easy I have a lot of other program and integration in my work flow If ticktick cant integrate with especially or at least Google calendar Im not going to use it. There is Google calendar sync but its not enough. Todoist do it batter
