One-liner
A simple, no-frills app that generates pure tone sound waves at user-defined frequencies for audio testing, meditation, or scientific use.
Strengths
- Generates precise, stable frequency tones with minimal latency
- Clean, minimalist interface focused on core functionality
- Supports a wide range of frequencies (from 1 Hz to 20 kHz)
- Highly rated for accuracy and reliability in niche use cases like tinnitus therapy
- Available in multiple languages (Spanish, Japanese, French, Italian)
Weaknesses
- Sounds stop when the phone goes to sleep or screen turns off — users report this makes it unusable for long sessions
- Requires the app to remain open and phone unlocked — described as 'counter productive for anything other than novelty'
- No background playback support despite being a utility for continuous sound generation
- Users express they'd buy it if it worked during standby, indicating a key feature gap
- No option to save or export custom frequencies, limiting reuse
Opportunities
- Build a version with background audio mode (iOS background audio capability) to allow sounds to play while screen is off
- Add a 'sleep timer' or 'auto-stop' feature for meditation/therapy use cases
- Introduce preset libraries (e.g., binaural beats, solfeggio frequencies, tinnitus relief) to increase perceived value
- Offer a free tier with limited features and a paid upgrade for advanced controls — addresses the 'would buy if' sentiment
- Optimize for accessibility by adding visual feedback (waveform display) and haptic cues
Competitors

- Pure Tone Generator
