HànHàn (汉汉) is a static web app to learn Mandarin from Swedish. What is a bit special is that it start by teaching its own UI vocabulary, like "返回" for "return" ("tillbaka" in Swedish) that is used to return to the main screen from an ongoing lesson.

At start everything is in Swedish, but as you learn more words, they will be either shown in both Swedish and Chinese as 返回 in the screenshot above. Later, when the user has shown they know a word or phrase repeatedly only the Chinese is displayed, ultimately turning the full UI into Chinese, the first step to be able to understand and use Chinese mobile apps.

Except for its gradually translating UI, and the type of words you learn, the app is quite standard. You learn both Pinyin and the Chinese characters and it uses SRS (Spaced Repetition System) to train on already learned words.

It's a static web app, and is optimized for use both from desktop and mobile. The app packaged as a PWA, meaning you can install it like a normal app if you prefer.

I created HànHàn mainly to motivate myself to improve my Chinese. I have previously both lived and worked in China, have a Chinese wife and travel there from time to time, but my own Chinese skills are definitely not great. I hope it will improve as part of my work on HànHàn!

Tech wise its more or less vibe coded, but I think so far it's been working out great.
