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

One-liner

A portable, high-precision audio signal generator for testing, calibration, and educational use, offering sine, square, triangle, and sawtooth waves with adjustable frequency and amplitude.

Strengths

Highly accurate frequency generation across a wide range (0.1 Hz to 20 kHz) as confirmed in multiple reviews
Clean, minimal interface focused on core functionality without bloat
Supports real-time frequency and amplitude adjustments with smooth sliders
Popular among educators and hobbyists for physics and electronics labs
Consistently praised for reliability and low latency in audio output

Weaknesses

No waveform export or recording feature—users request this repeatedly in reviews
Limited customization: no option to save presets or create custom waveforms
No support for external audio input monitoring or analysis
Some users report instability on older iOS devices (e.g., iPhone 6s)
Lacks visual feedback like oscilloscope display or spectrum analyzer

Opportunities

Add waveform export (WAV/MP3) and recording to enable use in tutorials and documentation
Introduce preset management and user-defined waveforms via simple scripting or parameter sets
Build a lightweight oscilloscope view to visualize output in real time
Create a companion app for audio testing (e.g., speaker response, microphone calibration)
Offer tiered pricing: free version with basic features, pro version with advanced tools
