Kıble Pusula

Kıble Pusulası (Qibla Compass) is our focused utility app that accurately determines the direction of the Kaaba in Mecca from the user's current GPS location using a combination of device compass, accelerometer, and GPS data fusion. Accuracy and reliability in all conditions—indoors, in basements, on moving vehicles—were the primary design constraints.

Sensor fusion is the technical core of the app. Consumer-grade phone compasses are affected by magnetic interference from metal structures, electrical wiring, and nearby electronics. Our calibration algorithm continuously monitors sensor readings for anomalies and prompts users to re-calibrate when interference is detected, maintaining accuracy in environments where a naive compass implementation would give wrong answers.

The interface is deliberately minimal: a compass needle, the Qibla direction indicator, and GPS coordinates. Daily-use utility apps should not require the user's attention beyond the task they opened the app for. Loading time is under two seconds, the main screen is immediately functional, and there are no unnecessary navigation steps.

Kıble Pusulası demonstrates our sensor integration experience and our discipline in building focused utility applications that work reliably across a wide range of device types and environmental conditions. It is a reference for clients building any location or orientation-dependent mobile feature.
