How can we help?

On an empty list, tap one of the six starter ideas, or tap “Add your own”. Later, tap the + button at the top. Pick an emoji, type a name and choose when you last did it (today by default), then tap Add.

Tap “Did it today” on the item. The count goes back to today and the date is saved to its history. The button then reads “Done today” until tomorrow.

Tap Undo in the message at the bottom of the screen. It stays for five seconds. If it’s gone, touch and hold the item and tap “Remove today”, or open the item and swipe left on that date in its history.

Open the item, tap “Add a past date” and pick the day. If it’s newer than the last date, the count updates. Future dates can’t be picked.

Open the item and tap Edit. Change the name or emoji and tap Save, or tap “Delete item” to remove it and all its history. Deleting can’t be undone.

Touch and hold an empty area of your Home Screen, tap Edit, then Add Widget, and search for LastMark. The small widget shows one item: touch and hold it, tap Edit Widget and choose the item. The medium widget shows your three longest gaps. Tap a widget to open that item.

In calendar days, in your phone’s current time zone. Something done at 11 pm yesterday reads “1 day” this morning. Dates are stored as plain calendar days, so travelling never shifts your history.

The longest gap is always on top. Items with the same count are sorted by name.

No. LastMark works fully offline and never connects to the internet. Your data stays on your iPhone. See the privacy policy.
