You're listening. You miss one word — three more slip past.
While you're stuck on one, the rest keeps moving. TonesFly breaks that cycle. Any audio becomes a live, interactive lesson — phrases pause so you can breathe, words appear so you can tap and discover, and you can finally start keeping up.

You hear a word you don't know. Then what?
Miss one word — lose the rest.
One unfamiliar word slows you down. The speaker keeps going. By the time you recover, the sentence is already over. That's your Cognitive Span: how long you can hold on before comprehension starts to slip.
