Visual qiblah for Android

Visual qiblah app for android description: Why visual qiblah? Visual qiblah was developed to overcome the pitfalls and shortcomings of many other qibla applications: north measured by mobile sensors may vary up to 90 degrees from the true north consequently qibla calculated from north in mobile applications may result in a serious deviation from the qibla direction.
Visual qiblah considers this reliability issue and overlays the qibla on google maps so that the user can visually verify qibla with nearby features such as buildings streets and do the needed alignment.
Magnetic deviation induced by nearby metallic objects (e.
G.
Mobile leather case) and electronic devices can cause the sensors to behave unpredictably.
Visual qiblah identifies abnormal magnetic field strength and warns the user.
Magnetic declination (the angle between true north and magnetic north) at user s location is another source of confusion (e.
G.
In the south america magnetic declination reaches 17 degrees).
Visual qiblah calculates qibla from true (geographic) north.
Additional information about qibla from magnetic north at user s location is also provided for those who prefer to use real compass.
Visual qiblah uses formulae to calculate qibla that are accurate to within 0.
5 mm (0.
020 ) on the earth.
Visual qiblah pro includes 3d qibla qibla search as well as any future enhancement to qibla finding: 3d qibla (augmented reality) provides a 3d view of qibla in real world environment (in app purchase).
This feature requires an access to the camera.
Search the map to quickly find qibla from places you are interested in.
You can search for all kinds of things like addresses buildings or street names (in app purchase).
