## Undo today

Tap the check of a habit that’s done and it goes back to not done. Right after you tick something, the toast also has an **Undo** button.

## Fix an earlier day

Forgot to log yesterday? You can change past days in several places:

- **List view** on Today shows the last 5 days. Tap a day.
- The habit’s **Calendar** tab: open the habit, choose Calendar, and “Tap a day to change it.”
- **Paper log** view on Today: tap any day this month.
- The **Planner**: pick the day in the week strip and tick it there.

## What you can’t change

Future days, and days the habit isn’t scheduled, can’t be ticked.
