How do I find contacts with no follow-up planned?

In Contacts, tap the Sort & Filter button (the sliders) at the top, tap Add filter, choose Follow-up, then pick a value and tap Apply. Upcoming shows contacts with a follow-up that's still ahead and that you haven't visited since. None upcoming shows everyone else, so you can find people you haven't planned a return visit for. Missed shows contacts whose follow-up passed more than 4 hours ago, within the last 30 days, with no visit since: the same people as your missed follow-up reminders. Dismissed follow-ups don't count. To see who's next, choose Next follow-up under Sort: each contact then shows when their follow-up is due in place of their last visit. The soonest follow-up comes first with Descending, the latest with Ascending, then missed follow-ups, and contacts with none go last. Other sorts, like Bible Study, Date added, or City, show the value they sort by in the same place. Follow-up filters work on iOS and Android, apply to the list and the map alike, and can be part of a saved view. They're worked out on your device, and nothing is shared. If a contact appears where you don't expect, open their most recent visit and check its follow-up date, or whether a later visit already answered it. For anything else, contact support from the Help Center and leave out names, addresses, and notes.
