One-liner
A simple, no-frills app that generates pure tones at specific frequencies (Hz), with support for multiple waveforms and basic tuning tools.
Strengths
- Highly accurate frequency generation across sine, square, triangle, and sawtooth waves
- Clean, minimal interface focused on core functionality—users appreciate the lack of clutter
- Supports custom Hz input down to 0.1 Hz, useful for scientific or therapeutic use cases
- Built-in tuning reference for A440 and other standard pitches
- Strong keyword ranking in both English and Japanese (e.g., 'fréquence', '周波数')
Weaknesses
- No audio export or recording feature—users complain about inability to save generated tones
- Limited waveform customization (e.g., no phase control or modulation options)
- No visual feedback like spectrum display or oscilloscope view—'just a tone, no visuals'
- Some users report inconsistent behavior on older iOS devices: 'crashes when switching waveforms'
- No dark mode despite demand: 'why is this still light-only?'
Opportunities
- Add audio export (WAV/MP3) with metadata tagging for therapists, musicians, or researchers
- Introduce a spectrum visualization or real-time frequency analyzer as a premium add-on
- Build a library of known therapeutic frequencies (e.g., 528Hz, 432Hz) with context cards
- Offer a dark mode and accessibility improvements to address user complaints
- Target niche audiences like sound healers or audiologists with pre-set frequency profiles
Competitors
- Tone Generator Pro
- Sound Frequency Generator
- Pure Tone Generator
