Compass: Qibla & Bubble Level

FightTech VN

About this app

Compass & Level packs a true-north compass, qibla finder, feng shui ring, bubble level, screen ruler, protractor and flashlight into one fast, offline toolbox — no ads, no account, and no interstitial standing between you and the tool.

Magnetic interference can push a compass 15–30° off. This one shows a live accuracy badge and coaches you through the figure-8 calibration that actually fixes it.

ALL THE CORE TOOLS ARE FREE

✓ Smooth compass — fused rotation-vector sensor with a critically-damped needle: settles fast, never jitters
✓ True north or magnetic north — declination computed on-device from coarse location; no network needed, and the compass still works if you decline location
✓ Accuracy badge + calibration coach — color-coded sensor accuracy with an animated figure-8 guide; opens automatically when the sensor turns unreliable
✓ Qibla mode — great-circle bearing and distance to the Kaaba drawn right on the dial; pure math, works fully offline anywhere on Earth
✓ Feng shui compass — the traditional 24-mountain ring plus the 8 Bát Trạch trigrams with their elements; your current mountain is highlighted and named under the heading
✓ Bubble level — surface mode (2D bubble), edge mode (horizontal/vertical bars) and slope mode, 0.1° resolution, hold button to freeze a reading
✓ Slope / inclinometer — the same tilt in degrees, percent grade (%) and roof pitch (x:12), the units roofers and builders actually use
✓ Set zero on any surface — lay the phone on a reference surface and zero it; every later reading is relative to that surface, and the offset survives a restart
✓ Audible level alert — beeps faster as the bubble nears centre so you can level a surface you cannot see behind a fridge or under a shelf
✓ Bearing lock — lock the heading you want to walk, then follow the turn-left / turn-right hint and the back-bearing
✓ Magnetic interference warning — live field strength in µT with a warning when metal, magnets, speakers or a car dashboard are throwing the needle off
✓ Screen ruler — real mm/cm and inch marks, two draggable markers, and a one-tap calibration against a bank card or a real ruler because manufacturer DPI is often 5–20% off
✓ Touch protractor — two rotating arms, 0–180° at 0.1°
✓ Flashlight, keep-screen-on, length unit converter (mm/cm/m/km/in/ft/yd/mi)

WHY PEOPLE CHOOSE THIS COMPASS

• No interstitial ads before the tool opens — ever. There are no ads at all.
• Calibration is explained on screen, with a guided figure-of-eight and a live accuracy readout.

What’s new

1.2.0

• Reversal calibration for the level. Setting zero assumes your surface is level — this doesn't. Capture, turn the phone 180° on the spot, capture again: the app separates how far the phone is off from how far the surface really is out.

• Sun check for the compass. A distorted field can leave a compass 90° out while the sensor still claims high accuracy. The sun doesn't lie.

• Heading shows its real wobble as a ± figure, and no number at all when the sensor says it can't be trusted.
