There is a distinction almost no app roundup makes clear, and it changes everything: most conversation apps pair you with a stranger. Very few are built for practising with people you already know. If you have a friend, a sibling or a partner who wants to learn alongside you, most of the options were not designed for you.
Why practising with someone you know is different
With a stranger, the conversation has to be invented. You share no context, so it becomes an interview — where are you from, what do you do — and dies in three exchanges. This is why most exchange pairings last less than a week.
With someone you already talk to, the topic exists already. You were going to speak anyway. The practice does not need to be created, only redirected — which removes the single point where almost every method fails, namely surviving past two weeks.
There is also the embarrassment problem, which nobody says out loud: writing badly to a friend is awkward for two seconds. Writing badly to a stranger who is evaluating you is awkward enough that you write less, then stop.
The real options
An ordinary group chat
The default everywhere, and the most fragile. It works for a few days and then stalls for the same reason every time: nobody can write in the target language yet, so the group reverts to the shared language and never comes back. We wrote about why this happens in detail.
Worth it when: you are all already intermediate and can sustain whole sentences.
HelloTalk, Tandem, Speaky
Good products, but built for exchange: the core value is finding a native stranger. You can add a friend, but then you are using a discovery app for something that needs no discovery, and without the features that would help a pair who already know each other.
Worth it when: you have no partner and want to find one.
Pangea Chat
Of the competitors, the closest to this idea — writing practice with friends and classmates, with a bot for when nobody is online. If that is exactly your case, worth a look before you decide.
Tokki
Ours, so weigh it as you like. The mechanical difference: instead of you both trying to write in the new language, the words you add to the group's vocabulary replace themselves inside your messages. You keep writing normally; the proportion in the target language rises as the vocabulary grows.
That solves the group-chat problem specifically: nobody needs to be able to write in the language for the group to start operating in it. And the vocabulary is shared, so a word one person adds becomes everyone's — which is what lets mixed levels coexist in one conversation.
Not worth it when: you want speaking practice. Text does not fix pronunciation or real-time listening, and we are not going to pretend it does.
Comparison
| Built for people you know | Works for a total beginner | Needs a scheduled slot | |
|---|---|---|---|
| Ordinary group chat | Yes | No | No |
| HelloTalk / Tandem | No | Hard | No |
| Lessons for two | Yes | Yes | Yes |
| Tokki | Yes | Yes | No |
Three rules that make any of them last
Whatever the tool, pairs and groups die for the same reasons. Agree on this in the first message:
- Corrections only when asked. Unsolicited correction kills study groups faster than anything else. The corrected person writes less, then stops.
- No scheduled sessions. The moment it becomes an appointment it joins the queue with everything else in your week, and loses.
- Start with one word, not one sentence. Switching a whole conversation into the new language lasts a day. One word per message lasts months.
