Muolingo
Read full descriptionHide full description
This is a language learning app designed to help beginners quickly get started and understand the core elements of a language. If you're someone who plans to travel the world, this app is perfect for you. The main learning method is "listening." To achieve this, the app has incorporated many design features to help learners focus on listening. For example, Muolingo's interface is extremely minimalist, aiming to eliminate all distractions and allow you to focus on learning the content. The learning material is also streamlined, consisting of just a pair of sentences—one in your native language and one in the language you are learning. After that, you must listen to the audio of these two sentences. In fact, you can simply listen to the audio provided by the app. Since the app allows playback even with the screen locked, you can learn at any time—while running, walking, driving, on the bus, or at work... This way, you will quickly develop a deep and true memory of the language. The reason it’s called Muolingo is based on the original idea behind the app’s design: to support multiple languages. Yes, it supports 15 languages, including: zh, en, ja, ko, de, fr, es, ar, ru, pt, it, el, th, vi, hi. You can learn any of these languages. You can use Japanese to learn Spanish, or vice versa. Muolingo’s content ranges from beginner to A2 level, covering similar material to Duolingo. Additionally, for Japanese, the app provides furigana (pronunciation in kana) for kanji. I hope you enjoy it and that it truly helps you learn efficiently. Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
