One-liner
A minimalist, high-contrast frequency counter app for measuring sound and vibration frequencies using the device's microphone.
Strengths
- Accurate frequency detection with real-time visual feedback ("works perfectly for tuning instruments" - review)
- Clean, distraction-free interface optimized for quick measurements ("simple and effective, no bloat" - review)
- Supports both audio tones and physical vibrations via microphone input
- Highly responsive with low latency in frequency tracking
- Runs efficiently in background without draining battery
Weaknesses
- No export or history feature ("would be great to save readings" - review)
- Limited calibration options for different microphone types ("needs better mic sensitivity adjustment" - review)
- No support for external microphones ("only works with built-in mic" - review)
- No audible output or pitch reference ("just a number, no tone to compare to" - review)
- No settings persistence across app restarts ("loses my preferences every time" - review)
Opportunities
- Add basic data logging and export (CSV/JSON) to enable use in scientific or musical workflows
- Introduce customizable pitch references (e.g., A440, concert pitch) with audible playback
- Support external USB/Bluetooth mics via Core Audio (expand usability for field work)
- Build a companion web dashboard for historical trend analysis
- Add calibration wizard for different devices/microphones to improve accuracy
