When you add an item from the Item Library — or a scan matches one — Homvio offers to Schedule Reminders for its recommended maintenance. Items you type in yourself don't come with a schedule. Scheduled tasks appear under Up next on your dashboard and in the maintenance calendar.
When a task is done, select it in the calendar and choose Mark as Complete. It's added to the item's Timeline, so each item's history builds as you go.
Homvio reminds you as a task comes due — starting a week ahead — in the app, and by email if email reminders are on in Settings → Notifications.
