ZemTally: AI Traffic Counter

ZemTally turns an Android phone into an offline traffic survey assistant. Point the camera at a road, verify the live detection boxes, then start a session to count moving vehicles with duplicate-resistant tracking.

Designed for planners, traffic surveyors, students, researchers and smart-city field teams.

Key features:

- Live on-device vehicle detection with no video uploaded
- Cars, trucks, buses, bicycles, motorcycles and delivery riders
- High-view overlapping scan for distant traffic
- Motion-verified, multi-frame tracking to reduce duplicate counts
- Pinch-to-zoom, plus/minus controls and one-tap full-view reset
- Portrait and landscape survey operation
- Saved sessions with individual deletion and clear-all controls
- CSV reports, visual charts and vehicle distribution summaries
- Adjustable confidence, resolution, GPU and display settings
- First-use guide and permanent field survey instructions
- Optional rewarded ad for 30 minutes of ad-free survey use

Important: Detection quality varies with device camera, height, lighting, occlusion and road angle. Review survey results before using them for engineering or legal decisions.
