# What are factors in the journal?

Factors are your own words for what shaped a day, such as work, travel, a deadline or a migraine. Tap the ones that fit in the Factors pill of a journal entry, as many as apply. With Pro, [statistics compare your mood on the days with and without each factor](https://privacynotes.app/help/what-moves-mood/). Factors themselves are free.

Manage the list in Settings > Trackers > Factors, or tap **Change these factors** in the pill. Add several at once by separating them with commas. The list holds up to 200 factors of up to 40 characters each, and a factor you remove keeps its name on the days that already hold it.
