What it does
Tap, speak, stop
No mode to pick and no keyboard to switch. Tap Start recording, speak, tap Stop, then edit the text or copy it anywhere.
Audio never leaves the phone
Transcription runs on the phone CPU with a 17 MB speech model. There is no backend, no API key and no account.
Offline after setup
The model downloads once on first launch and is SHA-256 verified. After that it works on a plane, in a meeting, anywhere.
Seven languages, auto-detected
English, German, French, Spanish, Italian, Dutch and Polish — the app picks the language automatically.
Optional Whisper Base
Need more accuracy or a rare language? Add the optional 148 MB Whisper Base model for around 99 languages, downloaded only when you choose it.
History stays local
Transcripts, durations and word counts are stored on the phone. Copy, share or delete individual notes, including kept audio.
How it works
-
1
Install the app and let the 17 MB model download once. Wi-Fi is recommended for setup.
-
2
Allow microphone access when Android asks. Recording is active only between Start and Stop.
-
3
Tap Start, speak, tap Stop. Edit the result, copy it, or jump back to history.
Private by construction
There is no cloud in the loop. Audio is captured at 16 kHz, transcribed on the device, and the text is stored in a local database. The app opens the network once for the model download — never for your voice.

Questions
Does Whistle upload my voice?
No. The default engine transcribes on-device. The only network request is the one-time model download from the model host; the optional Whisper Base model is downloaded only when you tap Download in Settings. No transcripts are uploaded.
Does it work without an internet connection?
Yes, after the one-time model download. Dictation, history and settings all work in airplane mode.
How big is the download?
The default speech model is about 17 MB. The optional Whisper Base model is 148 MB and is only downloaded if you ask for it.
Which languages are supported?
Seven languages with the default engine: English, German, French, Spanish, Italian, Dutch and Polish, auto-detected. Whisper Base covers around 99 languages.
Is it free?
Yes. No account, no subscription, no ads and no tracking.
What permissions does it need?
The microphone, and internet access only for the model download. System dictation, if you choose it, uses Android's on-device recogniser and language packs.
0.5.0 — optional Whisper Base engine: a 148 MB model with around 99 languages, downloaded on demand, plus reliability and insets fixes from 0.4.4.
