Japanese Practice
Drill Japanese characters and see which ones you miss.
A local desktop application for learning Hiragana, Katakana and Kanji: multiple-choice flash cards, memory-training boards, native Japanese pronunciation, and analytics that show precisely which characters are failing. No account, no network, no telemetry.

Install
Clone, create a system-site-packages venv and install; a desktop-menu installer is included.
Requirements
- Linux, macOS or Windows
- Python 3.10+
- CJK font (fonts-noto-cjk) for glyphs
- WebKit runtime (gir1.2-webkit2-4.0) for the desktop window
git clone https://github.com/MensuraMedia/language-learning-flashcards.git
cd language-learning-flashcards
# --system-site-packages is required on Linux, or pywebview cannot find
# PyGObject and silently falls back to browser mode.
python3 -m venv --system-site-packages .venv
.venv/bin/pip install -e ".[dev]"./tools/install-desktop.sh- Uninstall with ./tools/uninstall-desktop.sh; it keeps your study data unless --purge
- Study data lives in ~/.local/share/japanese-practice/
- Without a WebKit runtime the app runs in browser mode instead
