SanSides — multi-sided flashcards for learning foreign words. Why should a flashcard have only two sides?

This language learning app is built around flexible flashcards and is designed for kanji study, Japanese, and other non-alphabet languages. It also includes an automatic language translator when you need quick support while studying.

I created this app for myself while studying languages and then decided to share it. It was created by an ADHD developer and an eternal student — for anyone who prefers to learn in their own way. This language learning app supports a more holistic style of learning, especially when you need to remember multiple readings or extra meanings of words. This often happens with kanji study, learning Japanese, Chinese, and other languages.

Build your cards the way you need them: word, meaning, reading, examples, personal notes — all in one place. Unlike classic cards, you can create flashcards with more than two sides and control how they appear. It is easy to edit cards during self study, so your learning flow never breaks. The interface stays minimal so nothing distracts you. This balance makes it a truly helpful app for students who want power without clutter.

Main features:

⭐ Up to 5 sides on a single card
⭐ Automatic translation to remove routine and help you start faster
⭐ Smart Mode with spaced repetition for efficient memorization
⭐ Full control over card order and study behavior
⭐ Web sync and offline access for continuous self study

This approach works especially well for Chinese language or Japanese language and kanji study. Supports your journey from JLPT N5 to JLPT N1. You can use it as a fast auto language translator while creating and reviewing your cards. It is a helpful app for students who want focused learning with reliable offline access.

Whether you focus on kanji study, vocabulary, or grammar, this language learning app adapts to your style. Use it as a language translator helper, build smart flashcards, and study Japanese with confidence. Turn practice into a quiz, let Smart Mode support you, and let knowledge stay longer. If you learn Japanese or Chinese, or prefer focused self study, this language learning app with flashcards, offline access, and language translator support is built to grow with you.
