One-liner
A simple, no-frills tone generator app that produces pure audio frequencies for meditation, sound therapy, or testing audio equipment.
Strengths
- Produces clean, stable sine waves with precise frequency control (up to 20kHz)
- Minimalist interface with intuitive sliders and real-time frequency display
- Highly rated for reliability in generating consistent tones ("works perfectly every time")
- Supports long-duration playback without crashes ("played for 30 mins straight")
- Popular for use in binaural beats and sound healing practices
Weaknesses
- No built-in presets or common frequency libraries ("I wish it had 432Hz or 528Hz preloaded")
- Lacks export or recording functionality ("can't save the tone I made")
- No visual feedback like waveform or spectrum display ("would be helpful to see what I'm generating")
- Limited customization: no volume envelope, fade-in/out, or modulation options
- No support for stereo or dual-frequency output ("only mono, which limits binaural use")
Opportunities
- Add curated frequency presets (e.g., 432Hz, 528Hz, Schumann resonance) with descriptions
- Introduce a simple tone recorder to save generated frequencies as audio files
- Implement a binaural beat mode with independent left/right frequencies
- Add visual feedback (waveform or spectrum) to help users verify output
- Offer a dark mode and accessibility improvements for longer sessions
