Not the two hours a grammar book asks for. Twenty-five minutes — the length of an Uber ride.
"I don't have time to learn Romanian" is true for almost everyone who says it, if learning means sitting down with a textbook. Dictation isn't that. You listen to a real sentence, type what you heard, see what you missed. No desk required.
A session is 25 minutes by default. That's a commute. A waiting room. The back of a cab, phone in hand, nobody watching — just the spaced-repetition algorithm quietly deciding what you get to hear again tomorrow.
The 25 isn't arbitrary — it's the Pomodoro Technique, baked into the product as the default session length. One pomodoro of full attention, then stop. I remember the conviction coming from a tweet, years ago — Elon Musk, as I recall, saying it works. Whoever said it, they were right for a boring reason: 25 minutes is short enough that you never negotiate with yourself about starting, and long enough for the algorithm to get real work out of your ears.
It's in your pocket now.
