Modern UI. Help view added.

- Safety Guardrails: Integrated input validation prevents physically impossible decibel entries (> 200 dB) while allowing for unrestricted distance and dimension inputs.
- Adaptive Layouts: Bug fixed for large iPhone screens and landscape use with an "elastic" keypad and flexible UI components that prevent clipping.

- Advanced Calculation Wizards: Specialized modules for Sound Level Summation/Averaging, Interference Compensation, Distance-based Propagation, and Box-Shaped Source (Enclosing Surface) analysis.
- Slot-Based Data Logic: A robust entry system that remembers specific parameter slots. Deleting a measurement now intelligently prompts for that specific missing value.
- Smart Keypad Behavior: Enhanced "C" and "CA" logic—clear your current typing buffer with one tap, or reset the entire calculation with two.
- Ergonomic Layouts: Built-in Left-Handed Mode flips the interface for optimal one-handed operation in the field.

Support for iPhones with FaceID

Uses taptic engine on devices where it is available

improved accuracy for calculation of sound propagation when distance to sound source is more than 100 meters.

- Calculation of sound propagation now possible for distances below 100m
