🛠 Key Professional Features:
• Relative Zero (Tare): Set any angle as your new 0.0° baseline. Perfect for matching slopes or ensuring two surfaces are perfectly parallel.

• Multi-Unit Support: Cycle through professional measurement units:
◦ Degrees (DEG): Standard angular measurement.
◦ Percentage (PRC): Essential for civil engineering and drainage.
◦ Rise/Run (MM/M): The construction industry standard for slope height.

• Hold (Freeze) Function: Balance your phone in a tight spot, tap "Hold," and read the measurement at your convenience.
• Acoustic Guidance: Level objects without looking at the screen. A "Geiger-counter" style beep increases in frequency as you approach 0.0°.
