See exactly which sound slipped
Every word you say is scored sound by sound. Green means you nailed it, red shows what to fix, and you can tap any sound to hear it from a native speaker.
Almost! Put the tip of your tongue between your teeth for "th". Tap it to hear it slowly.
24 levels, one evolving chameleon
Start with the sounds that give you away, like "th" and "r". Climb to word stress, rhythm and natural fluent speech. Bombo changes color as you level up.
A new color every few levels. Gold is waiting at 24.
It remembers your words
Daily practice brings back the exact words you struggled with, right before you forget them. Tricky sounds stay on your list until you clear them, twice.
