Show HN: Kiwi Notes – Simple audio-powered vocabulary app
app.copiaviva.comHi everyone! I built Kiwi Notes because I needed a simple tool for learning vocabulary with natural audio and my own custom word lists.
Most vocabulary apps are overloaded, gamified, or locked behind subscriptions. Kiwi Notes is intentionally minimal:
– Add your own words and phrases – Hear natural pronunciation instantly – Train with multiple quizzes (typing, flashcards, matching…) – Track difficult words automatically – Import vocabulary lists (CSV/TSV/Excel)
It’s available on iOS and works offline for most features. I would love feedback from the HN community — especially ideas on UI, onboarding, spaced repetition tuning, or anything you think would make it a better tool for language learners.

Thank you! Suggested technical details (for anyone curious) If anyone’s interested in the stack:
• Frontend: SwiftUI
• Audio: internal cache layer + fallback TTS
• Spaced repetition: hybrid SM2-like intervals
• Import engine: CSV/TSV auto-detection
• Offline mode: local fallback for review & audio playback If you’re into language learning tools, I’d really appreciate your thoughts on:
1. How to improve onboarding
2. Whether spaced repetition feels too aggressive or too light
3. Ideas for making the audio features smarter Thanks again for checking it out!
