Accurate GPS distance tracking

Uses the Haversine formula for distance calculation.

Shows GPS accuracy as ± meters.

Updates distance only after at least 3 meters of movement to reduce GPS drift.

Real-time pace and speed

Current pace (min:sec per km), average pace, and current speed (km/h).

Current pace is calculated with a 20-second rolling window to smooth short GPS fluctuations.

Automatic laps (splits)

Adjustable lap distance from 500 m to 5 km.

Records lap time and lap pace automatically.

Voice announcement when a lap completes.

Goal setting and progress

Session goals: set a distance goal (1–20 km) or a time goal (30 minutes–2 hours) and get an alert when you reach it.

Voice coaching (TTS)

Time updates every 5 or 10 minutes with elapsed time, distance, and pace.

Pace coach with a target pace (4:00–10:00 per km) and guidance when you are faster or slower than the target.
