The trap

The app finds you a partner and leaves the two of you to invent the method. No clock, no correction agreement, no next date.

Tandem's own blog calls it dilemma six: one great call, and then never spoke again.

02 / 09

Two rules

Tandem learning has run since the 1990s on reciprocity and autonomy. Both people gain equally, and each runs their own learning.

Plus one habit: split the time between the two languages on purpose.

03 / 09

100%

In a 1999 Trinity College Dublin study, two pairs wrote 100% in their target language. Neither person got a native model back.

It sounds like diligence. It is the opposite of a tandem.

30 / 30

In a Geneva and Hubei university exchange, the main complaint was a 30-minute split per language that partners did not keep.

Corrections came only when partners were forced to give them.

25 + 25

HelloTalk's own template: 25 minutes each, strict, with a five-minute correction window.

Tandem's rule: several 30-minute sessions a week beat one 2-hour session.

2 of 12

Only 2 of the 12 ranking guides tell you what to write in a first message.

Tandem's line: more than a simple Hi. Ask about one thing in their profile.

07 / 09

Book it

Decide the next call before you hang up. Only 4 of the 12 guides say so, and it is the rule that stops dilemma six.

Between calls: a voice note daily, a call weekly.

08 / 09

30 minutes

Our plan: 2 minutes of hello, 12 in Spanish, 2 of corrections, 12 in English, 2 to book the next call.

¿Quedamos el jueves a la misma hora? (Same time on Thursday?)

09 / 09

Bring a page

A paragraph from the Spanish book you are reading is the best topic there is. Real input, a real correction, and a reason to meet again.

The full 30-minute plan, the two studies and the 12-guide count are in the post.
