Are you struggling with the massive amount of content in the JLPT N1 exam? Do you keep forgetting what you’ve learned and don’t know when to review it? N1 MASTER is a comprehensive learning solution that uses the SRS (Spaced Repetition System) to automatically and scientifically move knowledge from short-term memory into long-term memory. Why choose N1 MASTER? - Smart SRS algorithm: The app automatically calculates the “perfect timing” for reviewing vocabulary, grammar, and Kanji—right before you forget them. You only focus on what you haven’t mastered yet. - In-depth N1 content: Vocabulary: Thousands of the most common words with real-life examples and audio. Grammar: Detailed explanations of structures, usage, and key notes. Kanji: Master the full N1 Kanji set with Sino-Vietnamese readings, On/Kun readings, and example compounds. - Share your decks with the community or download others’ decks to study. - Create private groups to study together and conquer JLPT N1 faster. - Visual progress tracking: Detailed statistics help you clearly see how much of the knowledge you’ve mastered and maintain a daily study habit. - Lightning-fast lookup: Smart filters and search let you review any knowledge in just seconds. - Minimalist interface: Stay fully focused on learning without distractions from unnecessary features.

Verdict
The clearest difference is ads: Act Study at none against N1 Master's shown. N1 Master's advantage is update cadence (fortnightly vs monthly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
