PaceOMeter

PaceOMeter is an iOS-first driving insight app that reframes speed as time-per-distance to show how small many speeding gains are in practice.

Repository structure

• Sources/CoreDomain: pace, delta, and time-gain calculations.
• Sources/LocationService: location/speed ingestion interfaces.
• Sources/DriveSession: session-state projection layer.
• Tests/CoreDomainTests: deterministic unit tests for math and formatting.
• docs/: product, workstream, and QA guidance.

MVP focus

1. Live speed ingestion.
2. Pace conversion (m:ss / 10 km or 10 mi).
3. Comparison against user-selected reference speed.
4. Remaining-distance time impact estimate.
5. Safety-first, glanceable UI surfaces.

Web app prototype

A browser-based MVP is available in web/ with the same core calculations used by the iOS app:

• Pace per fixed 10-mile / 10-km basis.
• Time delta versus a reference speed.
• Trip-level time impact for remaining distance.
• Optional GPS-based live speed via the browser geolocation API.

Run it locally with:

cd web
python3 -m http.server 8080

Then open http://localhost:8080.
