AI Watch Translator vs. the Built-in Translate App: What Differs

Apple's built-in Translate app is free and can translate offline once you download the languages. AI Watch Translator (formerly Translate Now) is cloud-first: typed and spoken translation need a connection, with two offline exceptions (the camera, and the Watch borrowing your iPhone). It covers 29 languages, carries your phrase books onto the Apple Watch, and has a Reply button so the other person can answer from your wrist. If you mostly travel without data, use Apple's app. If your language pair is missing from Apple's list, or you want saved phrases on the Watch, AI Watch Translator is the one to try.

Which one works offline?

Apple's. In Translate on the Watch you can download both languages of a pair and translate with no connection at all, on an Apple Watch Series 9 or newer or an Ultra 2 or newer. The iPhone app downloads languages too.

AI Watch Translator's camera works offline once you download a language pair. Typed, spoken and conversation translation use our server and need a connection. On the Watch they work with the iPhone left behind, as long as the Watch has Wi-Fi or cellular.

Since version 2.1 the Watch has one fallback. If you speak to it with no internet and your iPhone is nearby, the Watch sends the recording to the iPhone, which recognises the speech and translates it on the device (iOS 26 or later, and only for languages the iPhone can recognise offline). The result is marked "Offline on your iPhone: may be less reliable." Without the iPhone nearby, there is no translation. The full walkthrough is in how to translate on Apple Watch.

Which languages does each cover?

AI Watch Translator translates between 29 languages, the same set on the iPhone and the Watch. Apple's Translate covers around twenty. Check that both of your languages are on Apple's list before you rely on it.

What is different on the Apple Watch?

Both apps put a microphone front and centre, show the result in large type and can read it aloud automatically. The differences:

• Reply. Under a AI Watch Translator result is a Reply button that flips the direction. The other person speaks in their language and the answer comes back in yours, so a short exchange takes two taps.
• Phrase books. AI Watch Translator syncs the phrase books you build on the iPhone to the Watch, where you tap a phrase to hear it. This is part of Premium.
• Favourites. Apple's app saves favourite translations and syncs them through your Apple Account. AI Watch Translator has no favourites; phrase books do that job.
• Watch face. AI Watch Translator has a complication that shows your language pair and opens the microphone screen. Apple's Translate appears as a suggestion in the Smart Stack when you travel somewhere with a different language.

What is different on the iPhone?

Both have a conversation view for two people across a table. In AI Watch Translator it is its own tab: the screen splits, the top half is turned round to face the other person, and each half has its own microphone and language. You take turns; it does not listen on its own.

Camera translation also works differently. Apple's app translates text live in the camera view. AI Watch Translator reads the text from a photo you take or pick, puts it in the text box for you to check, and then translates it. Camera and photo translation are part of Premium in AI Watch Translator.

Apple's app also does live translation with AirPods. AI Watch Translator does not do that. It does add Home Screen and Lock Screen widgets, Control Center buttons for voice, camera and conversation, and a Siri shortcut: say "Translate with AI Watch Translator", answer "What should I translate?", and it speaks the result without opening the app. Siri translations count toward the same daily free allowance.

What does each cost?

Apple's Translate is free and comes with the iPhone and the Watch. AI Watch Translator gives you two translations a day and two camera photos on the free plan. Premium removes those limits and adds live camera translation, Say it differently and phrase books. It is sold only through the App Store, inside the app.

Where does your text go?

Apple's app can translate on the device once languages are downloaded. AI Watch Translator always sends the text and the two language codes to our server to be translated. Your history stays on your device: on the iPhone and, for the last 20 translations, on the Watch. Signing in is optional.

Q: Can AI Watch Translator translate without the internet?
A: Partly. The camera works offline once a language pair is downloaded. On the Watch, spoken translation can fall back to a nearby iPhone, which translates on the device and says it may be less reliable. Typed translation needs a connection.

Q: Does AI Watch Translator need the iPhone nearby on the Watch?
A: No, if the Watch has Wi-Fi or cellular. The Watch sends the translation request itself. The iPhone is needed to sync phrase books.

Q: Is AI Watch Translator free?
A: Two translations a day are free. Premium removes the limit and adds live camera translation, Say it differently and phrase books.

Q: Can I use both?
A: Yes. Keep Apple's app for places with no signal, and AI Watch Translator for languages Apple does not cover and for phrase books on the Watch.

AI Watch Translator is an iWatchly app for iPhone and Apple Watch.
