Your Apple Watch hears what you say all day. Each evening, Twicy picks the sentences you'll say most often and teaches you to say them in English — out loud.
Coming soon to the App StoreiPhone + Apple Watch · $9.99 launch week · No subscription
How it works
Wear your watch and live your day. Twicy keeps only the parts where someone is speaking — and with Voice ID on, only the parts that are you.
Your iPhone transcribes on device, cleans up what you said, and picks the sentences you'll need again. Each one becomes a card: what you said, and how a native speaker would say it.
Look at your own sentence, say it in English. Twicy listens, checks every word, and schedules the next review so it sticks.
Made for
The speaking test asks about you — your hometown, your work, your weekend. Memorized model answers sound memorized. Your own sentences don't.
Ordering, asking the way, “sorry, I'm running late.” The things you'll need to say abroad are the things you already say every day — in your own language.
A day with Twicy
Privacy
There's no Twicy account and nothing for us to collect. Your day stays on your iPhone and Apple Watch.
Recordings go from Apple Watch to iPhone directly, not through iCloud. Transcription runs on your iPhone.
With Voice ID on, sentences spoken by other people are dropped, not saved. Your voiceprint stays on your iPhone.
Twicy uses your own AI provider key, kept in the iPhone Keychain. Only sentence text is sent — straight to the provider you chose.

Yes — Apple Watch is what hears your day. Without one you can still open Twicy and try the full flow with sample data (Settings → Load sample data), but your own sentences come from the watch.
You learn English. Your own language can be Japanese, Korean, or Chinese (Taiwan). The app itself is in English.
Twicy has no servers, so it doesn't resell AI. You connect your own key from OpenAI, Google Gemini, DeepSeek, or any OpenAI-compatible provider. Twicy only sends short sentence text, so usage is light — check your provider's pricing for exact costs. You pay them directly; we never see the key.
Your watch keeps only the parts where someone is speaking. With Voice ID on (the default), Twicy checks each sentence against your voice and drops what other people said. Recording is shown on the watch and you can stop it any time.
Listening, transcription, and practice run on your devices. Turning your day into cards needs a connection to your AI provider. The first time you use a language, iOS downloads its speech model.
No. One purchase, and it's yours.
