Particle Quest: JLPT Japanese

Thinksview Team

About this app

Confused by は, が, を, に, and で? You are not alone. Particles are where most Japanese learners stall, and where most apps spend about two lessons before moving on.

ParticleQuest does nothing else. 36 lessons. 720 questions. Every single one built around a pair of particles that learners actually mix up.

WHAT YOU GET
• 10 worlds, 36 lessons, 720 quiz questions
• Core particles: は が を に で と や へ から まで も の
• 36 contrast pairs, including は vs が, に vs で, を vs に, に vs へ, と vs や, から vs まで, も vs は, の vs も
• Real scenes: classroom, home, station, shops, travel, everyday conversation

HOW IT WORKS

1. Learn the contrast. Each lesson opens with the two particles side by side, the rule, and minimal example sentences.
2. Answer in Japanese first. The question shows only the Japanese sentence. Reveal the English hint only if you need it, so you build intuition instead of translating.
3. Get the reason immediately. Every answer shows the correct rule, the common mistake behind the option you were tempted by, and a contrast example.
4. Let review find your gaps. Wrong answers are rescheduled automatically, and a confusion score tracks which pairs still trip you up.

WHY IT IS DIFFERENT
• Particles are the whole product, not a chapter inside a vocabulary app.
• A confusion dashboard, not just a list of wrong answers. See which pair is your weakest, then drill exactly that pair in a 5-question or 10-question session.
• Explanations written per question, not one generic rule reused everywhere.

BUILT FOR
• Beginners who still guess between は and が
• JLPT N5 to N3 candidates
• Self-learners who want focused grammar reps, not another flashcard deck
• Students reviewing before an exam or a trip to Japan
