### 3/5 — Live mode

*2026-04-14*

Would work better if there’s were a live version too where can receive the key from the mic on our phones or computers

**Developer response:** Thanks for your feedback. The app is designed for audio files only (not live mic input) as shown in the App Store page. We appreciate the suggestion and will keep it in mind for future updates. Always feel free to reach out at contact@rebelsproductions.com if needed, thanks!
