Perfect for leveling shelves, frames, furniture, tiles, or any DIY installation.

■ Level Measurement (Bullseye Bubble)
· 2D bubble gauge shows tilt in all directions at a glance.
· Pitch, Roll, and Tilt angles displayed to decimal-degree precision.
· Visual and haptic feedback when within the target level tolerance.

■ Slope Measurement
· Angle (°), slope percentage (%), and ratio (1:N) shown simultaneously.
· Target angle presets (0, 15, 30, 45, 60, 90°) with arrival feedback.
· Custom target angle input for any specific requirement.

■ Calibration (Zero Point)
· Save the current surface as reference (0°) to compensate for sensor offset.
· Calibration offset persists across app restarts.

■ Measurement Records
· Save results with labels like "kitchen shelf" or "living room frame."
· Review past measurements anytime in the history list.
· All records stored on-device only.

■ State Memory
· Last mode, target angle, unit, and tolerance are automatically saved — no need to reconfigure each time.

■ Home Screen Widget
· A widget showing the last measured angle without opening the app.

■ More
· Dark/light themes, portrait and landscape support.
· No internet, location, or camera permission needed — accelerometer only.
· No account or sign-in required.
