One-liner
An app that generates pure, adjustable high-frequency tones (up to 20kHz) for testing hearing, sound calibration, or tinnitus relief.
Strengths
- Generates clean, stable high-frequency tones with precise pitch control (users praise accuracy)
- Simple, minimal interface focused on core functionality (repeatedly mentioned as 'no bloat')
- Supports frequencies up to 20kHz, covering the upper range of human hearing
- Used by audiologists and testers for hearing assessments (review snippets cite clinical use)
- Lightweight and fast—launches instantly, consumes minimal battery
Weaknesses
- No visual feedback (e.g., waveform or frequency meter) during tone playback (review: 'can’t see what frequency I’m playing')
- Limited customization—no option to save presets or adjust duration beyond manual stop
- No export or recording feature (review: 'would be useful to record a test tone')
- No support for external headphones or audio routing (review: 'doesn’t work well with my wired earbuds')
- No accessibility features (e.g., voiceover support, dark mode)
Opportunities
- Add a real-time frequency display or spectrum analyzer to validate output
- Introduce preset library for common tests (e.g., 16kHz for tinnitus screening)
- Enable tone recording and export to share with doctors or for personal logs
- Support headphone calibration profiles for consistent output across devices
- Build a companion web dashboard to log usage patterns and track hearing trends
