I'm the maker — solo dev, no company, no budget. AILingo is an Android app for learning Mandarin with an AI conversation tutor. The bet: after you speak a sentence, it shows per syllable which tone you actually produced versus the target — "you said 2nd tone, it wanted 3rd" on the exact syllable. Most apps just score pronunciation pass/fail. Plus 500+ bite-sized lessons across 10 levels, SRS flashcards, graded readers, character-writing practice, HSK prep. https://play.google.com/store/apps/details?id=ailingo.chat Six weeks since launch, zero downloads, zero ad spend — this post is the entire marketing department. For anyone who's shipped to crickets: what was the first channel that actually moved the needle for you? And Mandarin learners: is per-syllable tone feedback something you'd open an app for, or a nice-to-have?   submitted by   /u/ImscoRead [link]   [comments]
