hussein-khalilon Ask HN: What app features actually help vocabulary stick long-term?

This makes a lot of sense. I really like the point about the upfront cognitive cost that matches my own experience too.

What you’re describing feels very close to why “personal” content sticks better: the story, the emotion, and the effort are all doing the heavy lifting, not the tool itself.

hussein-khalilon Show HN: Kiwi Notes – Simple audio-powered vocabulary app

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!
