What’s New Version 2.2.2

Fixed an issue where expired reflection phrases could increase every time you enter the reflection screen.

Description

Master Japanese through your own stories. Our AI translates and refines your diary entries into natural phrases you can use starting tomorrow. By reviewing these phrases based on the forgetting curve, you’ll be ready to speak when it matters most. Perfect for those who want to talk about their daily life fluently in Japanese! ◆ Features 1. Learn various expressions and nuances based on your own diary! Write in English, and the AI will translate it; write in Japanse, and the AI will proofread it. You can also learn alternative expressions and nuances for phrases that interest you. Additionally, the app supports text-to-speech, which you can use for checking your pronunciation or for shadowing practice. 2. Learn expressions you can use immediately at work! By writing about your daily life and work in your diary, you can expand vocabulary specific to your own experiences and needs more effectively than you would by studying for tests like JLPT or BJT. As a result, you'll naturally learn more expressions that you can use at work. 3. Ensure you remember what you've learned! Have you ever been in a situation where you couldn't remember something you had previously learned when you needed to speak Japanese? With nocos, you can steadily memorize phrases you've used in your diary by following a schedule based on data from the Forgetting Curve. ◆ Recommended for: • Professionals who use a second language at work but sometimes struggle with speaking fluently. • Individuals who attend language classes as a hobby and sometimes have trouble thinking of topics to discuss. • Long-time language learners who lack confidence in their speaking ability. • Anyone who hesitates in conversations because they can't remember the right expressions. ◆ Supported Languages • English • Japanese ◆ Terms of Use https://corp.panory.jp/nocos/terms.html

Build 884809858v2.2.02026-04-30 03:53:12
■ Dashboard Features ・Review History & Schedules: Added review history and upcoming review schedules for each phrase to the Phrase Details screen. ・Progress Visualization: Added a dashboard to My Page that displays phrase mastery levels through visual graphs. ■ Improved Review Selection Logic Previously, phrases that were missed on their scheduled review date were simply pushed to the next scheduled interval. This sometimes caused users to lose the opportunity to review those specific phrases if they remained skipped. The Fix: Phrases not reviewed by their scheduled date will now be flagged as "Overdue" and will continue to appear from the following day onward until reviewed. ■ Others ・Sorting Options: Added the ability to sort by Mastery Level in the Phrase List.
