Nine apps and devices that translate a spoken conversation, set side by side from what each company says about its own product. One of them is Nualingo. We make it, so we have tried to be plain about where the others do better.
Try Nualingo free for three minutesNo account and nothing to download. Three minutes a day on each device.
Start with Google Translate. It is free on Android and iPhone, handles more than 70 languages in live conversation, and notices by itself when one language stops and the other starts. If you have a recent Galaxy, Samsung's Interpreter is already on it, and on an iPhone so is Apple's Translate app. Both of those keep working with no signal once the languages are downloaded. Nualingo doesn't. It is for long conversations in the browser, where the other person installs nothing and you want to scroll back through what was said.
We have not run these against each other ourselves. Every fact about another product comes from that company's own pages, store listings or press, checked in October 2026, and the sources are at the foot of the page. Where a company does not say, the table says so. On a phone, scroll sideways to see every column.

It costs nothing, it is on both kinds of phone, and it covers more languages in live conversation than anything else here. The microphone notices when the other language starts, so nobody has to press a button. Try it before you pay for anything, us included.
One phone, both people speaking into one microphone, and the translation read aloud. Microsoft retired its conversations across several phones on 30 June 2026, but the one-phone conversation is still in the app.
It is built in, it covers 22 languages with Thai among them, and it keeps working with no signal once the language packs are on the phone. Each person taps their own microphone on a split screen, and you need a Samsung account.
It comes on the phone. In the Face to Face view each person reads from their own side, and the app can translate without anyone pressing the microphone button. With the languages downloaded, it translates on the iPhone itself.
The translation goes straight into your ear, which nothing else here does without extra hardware. It needs an iPhone 15 Pro or later and supported AirPods, and Thai is not one of its languages.
A pocket device with its own mobile data for five years in more than 170 countries, so it works abroad without a local SIM card. You hold a button for each turn. It costs $299.95 or more up front.
A long language list and apps on most platforms. Voice conversations need Pro, and so does translating text with no connection. Pro is sold by the week or the year.
Free, with no sign-in. It covers 14 languages, Korean, Japanese, Chinese, Thai and Vietnamese among them, and has a one-to-one conversation mode.
Ours. It opens in the phone's browser, so the other person installs nothing, and it keeps every sentence on screen with the translation under it to scroll back through. It is paid after three free minutes a day, and it does not work without a connection.
Three minutes a day are free on each device, with no account. Try it on the same conversation as Google Translate and keep whichever suits the two of you.
