Reminders that pop up where the task is, not when

Laststop is a US consumer productivity app that reminds users of tasks when they pass through a specific place.

Most reminders are time-based, but many tasks belong to a place, like an errand you only remember when you pass the right store. Laststop wanted reminders built around location.

That needed accurate geofencing to detect when a user enters a relevant area, local inventory identification so reminders are useful rather than generic pings, and dependable background location tracking on both major platforms without draining the battery.
