SentenceBand - 瞬間英作文

This is a practice app for "instant English sentence construction," where you look at a Japanese sentence and mentally reconstruct it into English.

It focuses on practicing so that you can instantly produce (or think) the words and expressions you already know, rather than relearning grammar.

You can practice thoroughly on your smartphone or in your spare time using a watch. You can continue at the same pace no matter which you use.

Recommended for:

・Those who know the words and grammar but can't produce English when they need to.

・Those who want to practice expressions in both business and casual situations.

・Those who want to practice little by little during their commute or in between household chores.

Main Features

500 sentences for intermediate to advanced levels, 5 scenes x 4 subcategories

The five scenes—Workplace/Meetings, Business Emails/Phone Calls, Daily Conversations, Travel/Outings, and Friends/Casual Chats—are subdivided into four subcategories, such as meetings and restaurants. You can pinpoint the situation you want to practice right now.
