Yap
Yap is a dictation app for Apple Silicon Macs, Windows 10/11, iPhone and Android: hold a key, speak, and the text is inserted at the cursor.

Note before using it: automatic insertion on macOS needs Accessibility permission, letting the app type into other apps.
- On-device recognition; the page states audio is not uploaded and it works offline.
- One subscription covers the Mac, Windows, iPhone and Android apps.
- A browser demo transcribes up to 60 seconds of English, using a smaller model.
