Why writing it down matters more than the conversation itself
A tandem or exchange conversation is genuinely useful for fluency and confidence, but the specific vocabulary and corrections that come up in it are easy to lose without deliberate review, since a single exposure in conversation is rarely enough to make something stick the way spaced repetition does.
A log also protects the fairness of the exchange
Because a language exchange typically trades roughly equal time in each partner's target language, a quick note on how the time actually split session to session helps catch a pattern where one language quietly gets less attention than the other over time.
Frequently Asked Questions
How often should language exchange sessions happen to be useful?
Consistency matters more than frequency β a shorter session every week tends to build more real progress than a long session once a month, since regular small exposure to corrections and vocabulary compounds better than an occasional long one.
Is an in-person exchange better than one done through an app?
Both work β an in-person exchange often has a more natural conversational flow, while an app-based one makes it easier to find a partner in a specific language pair and schedule around time zones. The consistency and follow-up habit matter more than the format.
