What this app is. What it isn’t. What you could build.

One-liner

An audio signal generator app that lets users create precise sine, square, triangle, and sawtooth waves with adjustable frequency, amplitude, and phase for testing, calibration, or sound design.

Strengths

Highly accurate frequency generation with support for precise Hz values (e.g., 440Hz, 1kHz)
Clean, minimal interface focused on core functionality without clutter
Supports multiple waveforms (sine, square, triangle, sawtooth) with smooth real-time adjustments
Low latency output suitable for hardware testing and tuning
Strong keyword ranking in 'frequenz', 'frequency', and 'frecuencia' — indicates strong discoverability

Weaknesses

No built-in audio export or recording feature (users ask: 'Where’s the save/export option?')
Limited customization: no envelope controls, LFO, or modulation options
No visual waveform display or spectrum analyzer (review: 'I can’t see what I’m generating')
No support for external audio input monitoring (critical for calibration workflows)
No dark mode despite being a utility app (review: 'Why is it so bright?')

Opportunities

Add audio export with customizable file formats (WAV, MP3) and metadata
Introduce basic modulation (LFO, AM/FM) to enable more creative use cases
Build a real-time oscilloscope or spectrum view to visualize output
Add dark mode and accessibility improvements for long-term use
Enable Bluetooth audio routing for testing speaker/mic systems
