Your phone’s magnetometer sensor is read several times per second. The heading is smoothed using linear angle interpolation so the dial rotates gracefully rather than snapping. The rose counter-rotates while the needle stays fixed — just like a real compass.

• Heading in degrees (000° – 359°) with 16-point cardinal labels
• Accurate display: 360° shows as 000° — no erroneous readings
• 5 dial styles: Classic, Military, Nautical, Minimal, Vintage
• Works fully offline — no internet or GPS required for this mode
• GPS coordinate panel: latitude, longitude, altitude, accuracy (with refresh)

Magnetic north can differ from geographic True North by up to 20° depending on your location. This mode applies the WMM-2020 (World Magnetic Model 2020) correction — the same model used by aviation, military, and professional surveying globally.

• WMM-2020 declination: accurate to ±2° worldwide
• Declination badge shown in heading area (e.g. +3.2°)
• Dial visually shifts by the declination amount
• Declination recalculated live as you move (corrects drift bug)

Calculates the bearing from your GPS location to the Kaaba in Mecca (21.4225°N, 39.8262°E) using the haversine formula on a spherical Earth model — the same calculation used in precision navigation systems. A green crescent arrow appears on the rotating dial and always points toward Mecca.

• Accuracy: within 0.01° from any point on Earth
• Distance to Mecca shown in km (e.g. 4,453 km from Delhi)
• Deviation bar: degrees left or right needed to align
• Alignment confirmed with green panel and text when within ±3°
• Live update: Qibla recalculated as you move to a new location

Lock your current heading with one tap and navigate a straight line — useful for dead reckoning through forests, returning exactly the way you came, or following a map bearing precisely.

• One-tap lock: saves current heading as the reference bearing
• Dashed target arrow + circular marker drawn on the rotating dial
• Deviation arc shows how many degrees you’ve drifted
• Sliding deviation bar: centre = on bearing, left/right = off course
• Live instruction: “On bearing” / “Turn right” / “Sharp left” / “Turn around”
• Re-lock and Unlock buttons; medium haptic feedback on lock

The full NOAA solar position algorithm — Julian day, equation of time, solar declination, hour angle — gives you sunrise and sunset times accurate to within a minute for your exact GPS position.

• Animated arc bar showing the sun’s current position through its daily path
• Sunrise and sunset in local time; day length (e.g. 12h 34m)
• Morning golden hour: 60 min after sunrise. Evening: 60 min before sunset
• “Golden hour” badge appears while you’re in the window
• Polar region protection: NaN/infinity guard prevents crashes at extreme latitudes
• Sun times auto-recalculate as you move

Reads GPS Doppler speed directly from the geolocator stream — the same technique used by dedicated sports GPS devices. Handles the Android quirk where GPS returns −1.0 for unknown speed (clamped to 0).

• Large 48px speed readout in km/h (or mph)
• Colour gauge: teal (slow) → amber (driving) → red (fast)
• Session max speed and total distance since app opened
• Smart activity: Stationary / Walking / Jogging / Cycling / Driving / Highway / Fast
• Speed badge also appears in the heading area

Vastu Shastra (Sanskrit: वास्तु शास्त्र) is the ancient Indian science of spatial arrangement — the equivalent of feng shui in the Hindu tradition. This mode overlays all 8 directional zones on the compass dial with colour, Sanskrit names, and live zone highlighting.

• 8 coloured sectors rotate with the dial — labels always point real-world directions
• Active zone highlights with a bright outer arc as you turn
• Heading badge: zone name + Sanskrit name (e.g. “Northeast · Ishan”)
• Direction tab: lord, element, energy type, auspicious colour, and remedy
• Room Guide tab: ideal rooms (green chips) and rooms to avoid (red chips)
• 5-room quick reference: entrance, pooja room, kitchen, master bedroom, study

Save your current GPS position as a waypoint and navigate back to it from anywhere. The purple flag arrow on the dial always points toward your pin. Distance and bearing update live with every GPS fix.

• Drop pin saves current GPS position — supports multiple waypoints (1, 2, 3…)
• Live distance: metres or km, updating with every GPS fix
• Bearing to waypoint: degrees + cardinal direction (updates as you move)
• ETA calculated from current GPS speed; shows “—” when stationary
• Course guidance: “On course” (green, ±5°) or “Turn left/right N°”
• Open in Google Maps, share as text/WhatsApp link, copy coordinates
