One-liner
A simple, no-frills app that generates pure tones at any frequency between 1 Hz and 20,000 Hz, with adjustable amplitude and waveform options.
Strengths
- Precise frequency control from 1 Hz to 20 kHz, ideal for audio testing and calibration
- Clean, minimal interface focused on core functionality—no distractions
- Supports multiple waveforms (sine, square, triangle, sawtooth) for different use cases
- Highly rated for reliability and accuracy in generating test tones
- Popular among audiophiles, engineers, and sound therapists for its consistency
Weaknesses
- No visual feedback (e.g., oscilloscope or spectrum display) to confirm output
- Limited export or recording features—users can’t save generated tones
- No built-in presets or common frequencies (e.g., 440 Hz, 528 Hz) for quick access
- No support for background playback or looping beyond basic tone generation
- Review: 'Great for testing, but I wish it could record the output or show a waveform'
Opportunities
- Add real-time waveform visualization to validate output and improve user confidence
- Introduce preset library for common frequencies used in tuning, meditation, and audio testing
- Enable tone recording and export as WAV/MP3 for sharing or documentation
- Support background playback for long-duration tests or sleep aids
- Integrate with accessibility tools (e.g., hearing test mode with calibrated dB levels)
