## What is N3 Countdown?

N3 Countdown turns a short vocabulary check, your test date, and available time into today’s N3 new-word and review targets.

Start with a 30-word vocabulary check. The app estimates coverage within its curated 1,200-word study set, calculates a time-bounded plan, and recalculates a test-day vocabulary forecast as your recall history and study pace change.

WHY IT IS DIFFERENT

• Diagnose your starting point before the plan is created
• Calculate today’s target from the test date, estimated gap, and available minutes
• Recalculate the test-day vocabulary forecast from your actual study pace
• Choose bounded catch-up options that never triple the next day’s new words
• Answer from interactive Lock Screen and Home Screen widgets; your answers update the same local plan and history
• Prioritize weak and confusable words in the app and on the widget

PRIVATE, OFFLINE STUDY

No account is required. Core study works offline, and N3 Countdown does not upload your study history.

TRY IT FREE

Complete the vocabulary check, preview three days of your plan, study the first 100 words, and complete up to 30 widget reviews. Upgrade with a non-renewing 90-day pass or lifetime N3 access. Prices are shown before purchase.

Coverage is an estimate for the vocabulary included in this app. It is not a JLPT score or pass probability. N3 Countdown is not affiliated with the JLPT organizers and does not provide an official JLPT vocabulary list.
