How does the احرامOS طواف counter work and how accurate is it?

The احرامOS طواف counter uses a sensor fusion approach combining your device's GPS signal with its built-in accelerometer to detect and count your circuits around the کعبۃ اللہ. The system establishes the starting point at the حجر اسود corner and monitors your movement pattern to identify each completed circuit. When a full circuit is detected, the counter increments automatically and provides a gentle vibration notification.

The counter works on multiple floors of the Haram, including the ground level, first floor, and rooftop طواف areas. Since GPS signals can be partially obstructed inside the Haram structure, the accelerometer data helps maintain accuracy by detecting your walking pattern and direction of movement.

Each طواف session is recorded with timestamps, total duration, and the number of circuits completed. You can manually adjust the count at any time. Historical طواف sessions are stored locally and can be reviewed in your حج journal.
