Google Translate Review
The dependable all-rounder
If you want one free app that handles almost every language and situation, Google Translate is still the safest default.
Where Google Translate shines
- Supports nearly 250 languages — the widest coverage of any free app
- Camera translation, handwriting, and voice conversation modes
- Free offline packs for dozens of languages
- Transcribe mode is useful for one-way lectures and presentations
- Quality drops on low-resource and long-tail languages
- Privacy-sensitive text is processed on Google servers
- Business document formatting is not its strength
Google Translate has been the household name in translation for good reason: it covers close to 250 languages, works on the web and every major mobile platform, and costs nothing. For travelers, the camera translation feature can turn a foreign menu or street sign into readable text in seconds, and the conversation mode handles back-and-forth spoken dialogue reasonably well.
The app also offers downloadable offline packs, which makes it reliable when you are off the grid or avoiding roaming charges. Its newer Transcribe mode can even turn a lecture or presentation into live captions in another language, which is why it scores well for classroom and presentation use cases.
Where it falls short is nuance. European and East Asian languages often sound more natural in DeepL or Papago, and long-form business documents can lose tone and formatting. Privacy is another consideration: text you enter is generally sent to Google servers, so it is not ideal for confidential medical or legal content. Still, for sheer breadth and zero cost, Google Translate remains the best all-rounder for most people.

Screenshots below were captured by our automated test rig on a real iPhone running the current App Store build.
The home screen: one box, three big modes
Google Translate opens ready to go: a text box, a microphone, your two languages, and three shortcuts at the bottom — Live translate for conversations, Camera for signs and menus, and Practice, a beta that quizzes you. The 'Advanced' pill at the top lets you switch to Google's newer, smarter AI model. There is nothing to set up.
Type, and the answer appears while you type
You don't press a translate button — the answer shows up as you type and settles almost instantly. In our tests on a real iPhone it was done less than a second after we stopped typing. Below the answer you get extra help: a speaker button to play it out loud to someone, a copy button, and a small dictionary showing other ways to say the same thing.
Picking from 249 languages
The language list starts with ones you've used, and has search and an A–Z strip for the rest. The little download icons matter when you travel: they show which languages you can save onto your phone. Do that on hotel Wi-Fi, and translation keeps working later with no signal at all.
Live translate: choose how the conversation works
Before a conversation starts, the app asks how you want it to run. Listening sends the translation to your headphones as the other person talks. Conversation plays translations out loud while you take turns. Text only just shows words on screen — good for quiet places. One catch: it's built for two people sharing one phone. If a whole group needs to follow along on their own phones, that's the job PolyPort.chat was built for.
Draw the words you can't type
The 'Write here' pad lets you draw a word with your finger. Sounds odd until you're staring at a Chinese character on a menu: you can see it, but you have no way to type it. Draw it, and the app figures out what it is. No other big translation app can do this.
Is Google Translate free?
Yes. The mobile apps and website are free, including offline language packs and camera translation.
Does Google Translate work offline?
Yes, but you need to download the language pack beforehand. Offline quality is slightly lower than online.
Is Google Translate private?
Standard use sends text to Google servers. Avoid entering sensitive medical, legal, or confidential information.
