what is findourdevices fr?

FindOurDevices is a mobile app that lets you track the location and movement of your own devices on a map, or share that information with people in a private group. Think of it as a mini version of Find My Friends or Life360. It is built as an example app to show off what MongoDB Realm can do, so it is as much a learning resource for developers as it is a working application. The app runs on iOS and Android and uses a map to display where each device is. When a device moves a certain distance, its location updates on the map for both the owner and anyone in the same group. The app only tracks location while it is open and running in the foreground, so it will not keep updating once you minimize it. It uses OpenStreetMaps instead of Google Maps by default, which means no Google API key or billing account is required, though the README notes some visual limitations on Android as a result. This project is aimed at developers who want to learn how to build real-time, location-sharing apps with MongoDB Realm's sync and permissions features. A founder or PM exploring a family-tracking or fleet-tracking product could use it as a reference for how the pieces fit together. The accompanying backend repository and detailed diagrams cover data modeling, partitioning, and how to handle privacy and permissions so group members can see each other's devices without exposing data they should not. What makes this project notable is how thoroughly it documents the thinking behind the data model. The diagrams walk through earlier versions that had privacy issues and explain how the design was changed to fix them. That makes it especially useful for anyone trying to understand not just how to build a synced location app, but how to reason about access control and data partitioning in a real product.
