I built this tool because I kept running into a specific pain point: I needed to analyze location data from hundreds of images for a timeline, but I didn't want to upload sensitive evidence to cloud-based EXIF viewers (privacy risk) or inspect files one by one (too slow).
Refloow Geo Forensics is a desktop app (Electron) that runs locally. It:
1. Batch extracts EXIF data from folder structures.
2. Visualizes GPS coordinates on an offline-ready dark mode map (Leaflet).
3. Automatically reconstructs a chronological timeline of movement based on timestamps.
It's open source (AGPL-3.0) and currently Windows-only (Linux/Mac support is planned if there's interest).
I’d love any feedback on the timeline visualization logic or suggestions for other metadata fields that are useful for OSINT work!
