Understand a document • You photograph or import a rental contract, official letter or form and get a plain-language explanation in your language. • You let the AI read the fields of a PDF form, check the answers it drafts, and export the finished PDF. Talk with someone • You use two-way voice mode to translate what each person says and hear the translation read aloud. • You type with Snap Keyboard in any app that allows custom keyboards to translate, correct grammar, change tone and draft replies. Full Access must be turned on. Sell something • You photograph an item and get a title and description sized for Vinted, OLX or Facebook Marketplace. • You paste the text yourself. Snap never posts anything. Keep your translations • Snap saves every translation on your phone together with its photo. Good for • Travelers reading menus, street signs and train timetables. • Anyone who needs to understand a contract, official letter or form in a language they do not read. • Talking with someone at a hotel desk, a pharmacy counter or in a taxi. • Selling used things online without writing the listing by hand. Works offline • You can translate typed text, camera text and photo text with no internet connection after you download the language pair in the language picker. • Offline translation uses Apple's on-device language packs, so the offline languages are the ones Apple supports on your device. • For offline use, choose the source language yourself. Automatic language detection needs a connection. • Text is read from the camera on the phone for Latin, Chinese, Japanese, Korean and Devanagari scripts. Other scripts need a connection. • Voice mode, document explanation, PDF form filling, the listing writer, keyboard AI actions and any language pair you have not downloaded need internet.

Some features send a photo or text to a cloud service to read, translate or explain it. The data travels over an encrypted connection and is not stored on Snap servers. • Usage statistics are collected without translated content. What Snap is not • Snap is not a certified translator. Translations and explanations can contain mistakes. • Snap is not legal advice. Document explanations help you understand a text, and a lawyer checks a contract. • Snap does not post listings or send forms for you. Requires iOS 18 or later. Point Snap at the next menu or letter you cannot read.

Verdict
The clearest difference is ads: Snap at none against UDictionary Translator's shown. Snap also leads on update cadence (weekly vs fortnightly). UDictionary Translator's advantage is ratings volume (9.3K vs 45) and rating (4.6 vs 4.4). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. UDictionary Translator sells 9 in-app purchases, starting at $2.49 per 7 days and Snap sells 12 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
UDictionary Translator holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: UDictionary Translator has 9.3K ratings behind it against 45, so its average is the more settled of the two. Written reviews point the same way: 59% of UDictionary Translator's written reviews are positive against 50% of Snap's.
UDictionary Translator ships an update fortnightly, Snap weekly. The most recent releases landed on October 26, 2026 and October 25, 2026 respectively.
