HelloTalk vs Tandem: Which Language Exchange App Fits You?

HelloTalk and Tandem are the two biggest language exchange apps, and they look alike at first: list your languages, find native speakers who want to learn yours, and chat. Use both for a week, though, and they feel different. This guide compares them on what actually changes your practice, then says who each one suits.

Olu is an independent app, not affiliated with HelloTalk or Tandem. Product names are used only for comparison. Features and plans of third-party apps change often; check each one yourself.

The short answer

• Pick HelloTalk if you learn best by reading and writing, want strong in-chat tools, and like a social feed where you can post and get corrected.
• Pick Tandem if you want one-to-one calls, a community that is vetted at sign-up, and less public noise.
• Use both if you can. Most of the frustration with either app comes from waiting for replies, and two pools of partners halve the waiting.

What each app is

HelloTalk describes itself as a language exchange app with text, voice and video chat, built-in translation, transliteration, pronunciation help and corrections. It adds a public feed called Moments, plus Voicerooms and livestreams for group speaking. It says it has more than 70 million learners and over 260 languages.

Tandem describes itself as an app where people teach each other, with text, voice notes, audio calls and video calls, and in-app correction and translation tools. You can filter partners by language, location and interests. It says it reviews every application before you can start.

Where HelloTalk is stronger

• Text tools. Tap a message to translate it, see a transliteration, or correct a line and send it back. For languages with a new script, like Japanese, Korean or Arabic, this makes a real difference in the first months.
• Moments. You can post a few sentences publicly and native speakers will correct them, even if you have no partner yet. It's a good way to get feedback on writing without starting a conversation.
• Group speaking. Voicerooms and livestreams let you listen first and join in when you're ready.

The usual complaints: lots of messages that are more about flirting than language, and a feed that can feel busy. Popular profiles get far more messages than they can answer, so many first messages go unread.

Where Tandem is stronger

• Vetting. Because applications are reviewed, Tandem feels more focused to many users. The trade-off is a wait before your first chat.
• Calls. Tandem leans towards real conversation: voice notes and audio or video calls are central, not an extra.
• Less noise. Without a big public feed, the app is mostly you and your partners.

The usual complaints: the review wait, fewer tools for reading and writing than HelloTalk, and, as on every exchange app, partners who stop replying after a few days.

The problem they share

Both apps work the same way at heart: you browse profiles, send messages and hope for a reply. That's fine for some people, but it has costs:

• Waiting. Your partner may be asleep, busy or chatting with twenty others. A reply can take a day.
• Choosing. Browsing hundreds of profiles is tiring, and the people with the best photos get the most messages.
• The first line. For a true beginner, writing the first message in a new language is the hardest part.

If that sounds like you, add a different kind of app alongside them.

A third option for text-first beginners

Olu is a free, ad-free, text-only chat app. On its Language learners planet, you set the language you're learning and tap to take off. People who speak that language and are learning yours are matched with you first, then anyone else on the planet. The person you meet is online now, so there's no waiting for a reply.

Every message is translated both ways, and the original is always visible. The language you're practising shows big and the translation small, so you read the real sentence first. You can write in your own language at the start and switch line by line. If a chat goes well, add each other as friends and pick it up later.

Honest limits: Olu is text only, with no voice, video, feed or correction tool. Its community is small, much smaller than HelloTalk or Tandem, so at quiet hours you may not find a speaker of your language at once; when that happens you're told. AI chat partners exist only outside the planet, on a regular flight, and they're always labelled AI. Read more in language practice with native speakers.

Which one to pick

Whatever you choose, the same habits matter more than the app: agree a 50/50 split of languages, ask for one correction per chat, and save three new phrases after each session.

On any app, keep your address and full name to yourself with someone new, and never send money to a chat partner. More in our random chat safety tips.
