## What is Klars?

I believe the best way to master a language is to understand it through its own words, not just by translating it into your native language. Currently, Klars is built for learning English, so all definitions and explanations are provided in clear, simple natural English.

Key Features:
Default Translator: Set Klars as your default translation app in iOS Settings, so you can translate from anywhere.
Learn in Context: Klars explains words in clear, simple English to help you think in English.
Build Your Dictionary: Save what you learn by turning words and texts into your personal study Dictionary.
Recursive Lookup: For deeper understanding, simply long-press any unfamiliar word inside an explanation to look it up instantly.

Support & Feedback: 
If you find a bug, please email me, I will reply as soon as possible. If you have a feature request, I will review it carefully. If it meaningfully improves the app, I will do my best to ship it in a future update.
