Hi Product Hunt! 👋 I'm a solo developer from Istanbul, and English is my second language. I kept meeting the same wall: people asked me to repeat myself, and no tool would tell me exactly WHICH sound was wrong without shipping my voice to a server. So Bombo does the opposite. The entire scoring engine (a custom phoneme model plus Whisper) ships inside the app. You speak, and about a second later every sound lights up green, yellow or red. Tap a sound, hear a native speaker, try again. Your recordings never leave the phone, by architecture rather than by promise. It even works in airplane mode. A few things I'm proud of: 🦎 One chameleon mascot, nine colors. The whole app changes color as you level up through 24 levels. 🧠 Daily practice is rebuilt every morning from the exact words you got wrong. 🌍 Launching in 27 languages, with localized screenshots for each. 🎁 1,016 hand-built exercises, all reachable on the free tier with a full free lesson every day, forever. 🎟️ Launch gift: 1,000 codes for a full year of premium, first come first served. Code BOMBOLAUNCH, redeem here: https://apps.apple.com/redeem?ct... This launch is mostly me collecting feedback. Tell me which English sound gives you the most trouble, or what feels off in the app. I read and answer everything.
