Bombo is your personal American English accent coach. Say a sentence, get a score in seconds, and see exactly which sounds slipped. A friendly chameleon keeps you company while you practice, and your voice never leaves your iPhone. WHY BOMBO WORKS - Sound-by-sound feedback: every word you say is scored sound by sound. Green means you nailed it, red shows exactly what to fix. - Tap to hear it right: listen to any sound or word from a native speaker, then try again. - A real journey: 24 levels and 133 bite-size lessons take you from tricky sounds like "th" and "r" all the way to word stress, rhythm, linking and natural fluent speech. - Your chameleon evolves: Bombo changes color as you level up. Gold is waiting at level 24. - Daily practice that remembers you: fresh themed exercises every day, built around the exact words you struggled with, brought back right before you forget them. - Weak spots: your trickiest sounds stay on your list until you clear them, twice. - Streaks, XP and badges make showing up every day the easy part. PRIVATE BY DESIGN Your voice is never uploaded. All speech analysis runs entirely on your iPhone using on-device models. Recordings are not sent to us or to anyone else, and they are never used to train anything. Lessons, scoring and feedback even work in airplane mode. That is also why your scores arrive in seconds. WHO BOMBO IS FOR Whether you are preparing for everyday conversations, job interviews, IELTS or TOEFL speaking, Bombo helps you sound clearer and more confident in English. If people sometimes ask you to repeat yourself, Bombo shows you exactly why, then helps you fix it one sound at a time. Lessons teach clear, natural American English. The app interface is in English. FREE EVERY DAY One full lesson or practice session is free every day, forever. Bombo Premium unlocks unlimited lessons and practice with weekly, monthly or yearly plans, and the yearly plan includes a 3-day free trial. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel your subscription anytime in your App Store account settings.
