  1. Yandex Translate

    2位。レビュースコア:68/100。App Storeの評価: 4.7★・7,265件の評価

    A strong text translator with an AI mode for complex sentences. Built-in dictionary with word saving and flashcard review. Photo translation is unreliable and noticeably lags behind the text mode. Known issue: the app mutes background music with no way to turn that off. Entering Chinese via pinyin breaks the keyboard layout. AI mode sometimes auto-switches back to fast mode.

    評価点:Word study built right into the translator: save, review, and remember words without switching to another app.

    不満点:Photo translation has no auto-detect and produces unpredictable results. Chinese character input via pinyin is technically broken.

    向いている人:Russian-speaking users learning a language who want to translate and save words to a personal vocabulary list in one place.

  2. iTranslate Translator

    9位。レビュースコア:52/100。App Storeの評価: 4.7★・525,135件の評価

    A full-featured translator with text, voice, and a keyboard extension. Covers over 100 languages. Relevant for the category.

    評価点:The built-in keyboard lets you translate right inside WhatsApp and other messengers without switching apps. Listening to pronunciation helps you both understand and reproduce a word.

    不満点:Translation quality is inconsistent across languages: Italian works better than French, and Greek transliteration contains errors. Voice translation occasionally produces wrong phrases without any warning.

    向いている人:Travelers and people who regularly message with foreign contacts and want to translate without leaving the chat.

  3. DeepL Translate

    3位。レビュースコア:67/100。App Storeの評価: 4.8★・13,275件の評価

    The best text translator in this batch for accuracy, which users with professional language knowledge confirm. Camera works but is slow (about 5 seconds per frame). Voice synthesis sounds dated. The app stopped remembering the language pair between sessions after one update.

    評価点:Translation accuracy when handling nuance: alternative phrasings, gender agreement, and register are all taken into account.

    不満点:After every launch the app resets the language pair to the default and does not remember your preference.

    向いている人:People who translate carefully and care about precise wording rather than speed.

  4. UDictionary Translator

    5位。レビュースコア:62/100。App Storeの評価: 4.6★・9,265件の評価

    Works as an overlay translator directly over WhatsApp and Instagram without switching apps. Built-in grammar check with multiple suggestions. Word list and personal dictionary mode. Weak spots: long messages get cut off, no full-screen support on iPad.

    評価点:Overlay mode: translate text in any app without copying or leaving. Multiple translation engines in a single interface.

    不満点:Long texts do not display in full. Grammar check does not show a correction when there is only one error.

    向いている人:Users who message in social apps in a foreign language and want to translate right inside the chat without switching apps.

  5. Microsoft Translator

    4位。レビュースコア:62/100。App Storeの評価: 4.8★・158,245件の評価

    A key tool in the category. Free, compact (around 20 MB), and no subscription required. Supports group conversations via QR code. Recent updates have hurt voice mode stability.

    評価点:Group conversation mode: multiple participants join via QR code and each see the translation in their own language in real time. Free with no usage limits.

    不満点:After recent updates, voice recognition started mixing up languages and dropping words. There is a 1,000-character cap on text input, and the app does not tell you until you hit it.

    向いている人:Anyone who needs a reliable free translator without subscriptions, especially for group meetings or business travel where translation into multiple languages is needed at once.
