Professional Decibel Meter: Analysis, Recording & Alerts Overview Developed for environmental acoustic measurements and noise auditing, this application transforms your mobile device into a professional sound analysis station. With advanced signal processing algorithms, real-time data visualization, automated threshold alerts, and location-based video documentation, it offers precise solutions for occupational safety, environmental inspection, and acoustic analysis needs. KEY TECHNICAL FEATURES Smart Threshold Alarm & Notification System: No need for constant screen monitoring. When noise levels exceed user-defined limits or standard safety thresholds (e.g., 90 dB), the application automatically sends instant notifications. This proactive warning mechanism allows you to immediately detect high noise exposure and helps protect hearing health. Video Documentation & Geo-Tagging: Verifiability of measurement data is essential. During video recording, the application overlays instant decibel (dB) values, GPS coordinates, date, and time directly onto the footage. This feature creates irrefutable visual evidence for noise violations, site inspections, and legal dispute resolutions. Dynamic Graphical Analysis: Sound fluctuations are monitored with millisecond precision via time-axis charts. Instant noise changes, peak points, and background noise levels are detailed within the graphical interface. Statistical Data Processing: Data obtained during the measurement session is analyzed to calculate: • Min: The lowest sound level detected. • Max: The highest noise peak level. • Avg: Time-weighted average value calculated automatically. Customizable Interface (UI): To ensure optimal readability under various lighting conditions, the application offers multiple color themes and options for both analog and digital gauge displays. CORPORATE & INDIVIDUAL USE CASES • Occupational Health and Safety (OHS): Automatic detection of noise limit violations in factories, workshops, and industrial sites. • Environmental Auditing: Monitoring noise pollution caused by traffic, construction, or commercial businesses for compliance. • Baby & Sleep Safety: Remote awareness when sound levels rise in a nursery or sleeping environment. • Acoustic Testing: Performance evaluation of sound insulation and audio equipment. Why Choose This Solution? • Proactive Safety: Warning system triggers upon limit breach. • Evidence Quality: Location and timestamped video records. • Data Reliability: Consistent results with calibrated algorithms. Digitize your noise measurement processes. Download now for professional analysis. *Legal Disclaimer: While this application provides high-precision measurements within the technical capabilities of mobile device microphones, it is recommended to use certified Class 1 or Class 2 devices for official expert reports and legal limit compliance.

Verdict
The clearest difference is in-app purchases: AppStash at none against Cuspart's 7. AppStash also leads on ads (none vs shown) and update cadence (monthly vs every 2 months). On price there is nothing between them.
