How do I complete a reminder?
Complete a reminder to clear it — completing writes through to Google Tasks. Changes are recorded in Activity. You can complete a reminder by voice or text, or from the reminder's card.
Because reminders are backed by Google Tasks, completing one here marks it done in Google Tasks too. If you completed one by mistake, mark it not-complete again from your reminders list and it comes back — in Lonzo and in Google Tasks.
There is no snooze today. Nothing moves a reminder to a later moment for you. If you want a different date, ask for a new reminder on the day you want it — for example, "remind me to send the contract Friday."
