Show HN: I speak 5 languages. Duolingo taught me none. So I built lairner
I'm Tim. I speak German, English, French, Turkish, and Chinese.
I learned Turkish with lairner itself -- after I built it. That's the best proof I can give you that this thing actually works.
The other four I learned the hard way: talking to people, making mistakes, reading things I actually cared about, and being surrounded by the language until my brain gave in. Every language app I tried got the same thing wrong: they teach you to pass exercises, not to speak. You finish a lesson, you get your dopamine hit, you maintain your streak, and six months later you still can't order food in the language you've been "learning."
So I built something different. lairner has 700+ courses across 70+ languages, including ones that Duolingo will never touch because there's no profit in it. Endangered languages. Minority languages. A Turkish speaker can learn Basque. A Chinese speaker can learn Welsh. Most platforms only let you learn from English. lairner lets you learn from whatever you already speak.
We work together with some institutes of endangered languages to be able to teach them on our platform.
It's a side project. I work a full-time dev job and build this in evenings and weekends. Tens of Thousands of users so far, no ad spend, no funding.
I'm not going to pretend this replaces living in a country or having a conversation partner. But I wanted something that at least tries to teach you the language instead of teaching you to play a language-themed game.
Happy to answer anything.

Discord Voluntarily Pushes Mandatory Age Verification Despite Recent Data Breach
Show HN: 1MB iOS apps designed to reduce mental open loops
I’ve been building a small set of ultralight iOS apps (each ~1–1.3MB) around a simple idea:
Most of us carry too many mental open loops.
Not emotional crises. Just unfinished background processes.
Unsent replies. Half-made decisions. Things you’re afraid to forget. Conversations you keep replaying.
Modern software creates a lot of these. Notifications, feeds, reminders, partial attention.
The mind keeps threads active because they don’t have a clear endpoint.
Most productivity or wellness tools try to optimize behavior. These apps try to reduce load instead. The focus is load management, not behavior change.
Current set (v1.3):
• MindFlipOut — Catch a looping thought and give it a response so it stops reloading. • MindShoutOut — Externalize a heavy thought and let it return later instead of carrying it. • MindZoneOut — A blank, intentional stillness screen where thoughts can settle without input. • MindEaseOut (integrated) — A simple time-based release layer for thoughts that belong to the past or future, not now.
All apps are:
• Local-first (no accounts, no cloud) • No streaks, no tracking, no gamification • Designed to be used briefly and then closed
Each app is intentionally small (1–1.3MB total size) and runs entirely on-device.
The goal isn’t self-improvement. It’s reducing cognitive residue.

Curious how others think about “mental open loops” in the context of modern software.
