What is Bombo?
Most pronunciation apps upload your voice to a server and hand you one vague score. Bombo does the opposite. Say a sentence and every individual sound is scored in about a second, fully on-device: recordings never leave your iPhone and lessons work in airplane mode. Tap any sound to hear a native speaker, then retry. 1,016 exercises across 24 levels, plus daily practice rebuilt from your own mistakes. One full lesson free every day, forever.
