What the app is for
Fun Spectrum Analyzer is provided for entertainment, education, visualization, and casual audio reference. It is not a calibrated, certified, scientific, medical, workplace-safety, or regulatory measurement instrument.
Measurements are estimates
Decibel and SPL readings are estimates. Results can vary with device model, microphone direction, case, input route, Bluetooth route, environment, calibration, clipping, and settings. Do not rely on this app for hearing-safety decisions, legal compliance, equipment protection, emergency decisions, or any situation requiring certified measurement equipment.

Purchases and availability
Fun Spectrum Analyzer is free to download with a limited selection of modes and themes. An optional one-time in-app purchase unlocks Full Access; there is no subscription.
