Who is it for

Real-world User Experience

Is it Worth Paying For?

The app is free (no paid plan indicated). For most users, the included real-time frequency measurement, customizable waveform, and spectrum analysis provide strong value without cost.

How it Compares to Alternatives

Compared to tuners like gStrings or n-Track Tuner, Frecuencia leans more toward raw frequency and spectrum analysis than note-by-note guidance. Against spectrum tools like Spectroid or Sound Analyzer, it stands out with a customizable waveform plus real-time frequency readout, though dedicated pro analyzers may offer calibration profiles, peak hold markers, logging, and export.

Summary

Frecuencia delivers accurate real-time frequency measurement, a flexible waveform display, and practical spectrum analysis in a clean, no-cost package. Its feature set covers the essentials for tuning and on-the-spot signal inspection, with customization that helps tailor visibility to different environments. While professionals needing calibrated measurements, logging, or advanced analytics may outgrow it, the app’s strong rating and broad adoption indicate it’s a trustworthy everyday tool for musicians, hobbyists, and field checks.
