# Trek Log

GPS route recording app for iOS. Records your location as you walk, hike, drive, or travel and builds a route entirely on-device.

## Export formats

- **KML** — standard geographic format, readable by Google Earth, QGIS, and most GIS tools
- **Animated GIF** — shareable animation of the route
- **MP4** — video playback of the route

## Key characteristics

- Local-first: no server involved at any stage
- No account required
- No tracking or analytics
- Routes saved to user's own iCloud Drive (user's storage, user's account)
- Does not do turn-by-turn navigation — absent by design
- Does not share location in real time — absent by design

## Technical implementation

- CoreLocation for GPS track recording
- KML generated entirely on-device
- AVFoundation for MP4 export
- Storage: iCloud Drive (user's own account and quota)
