You turn on your lock screen dozens of times a day. Turn those spare moments into Japanese study time.

"Spact Japanese" displays a snippet of Japanese conversation on your lock screen, helping you naturally become familiar with the language every day without having to set aside separate time.

It is not burdensome study, but the repetition of fleeting, brief moments. That is the study method that leaves the longest lasting impression.

· Those who want to start learning Japanese but lack the time to study

· Those who bought vocabulary books and textbooks but put them away after a few days

· Those preparing for JLPT N5 or N4 or wanting to solidify their basic conversation skills

· Those who need practical conversation skills ahead of a trip to Japan

· Those who want to enjoy anime and dramas more without subtitles

4. Solidify your foundation in spare moments with JLPT vocabulary, Kana quizzes, and surveys.

Five minutes a day is enough. Because what matters is doing it every day.

"Gap Japanese" focuses on consistency rather than flashiness. Short and light, yet every day.

After one month, meet yourself where Japanese is no longer unfamiliar.

Japanese begins the moment you turn on your phone next time. ## Rankings - #1,891,009 — Overall ## Similar extensions and apps - [틈틈봇 JLPT 일본어능력시험 (잠금화면자동학습+알람)](https://chrome-stats.com/d/com.tmtmapp.jlptkr) — 1,037 users - [WordBit Japanische Alarm](https://chrome-stats.com/d/net.wordbit.jpde) — 192 users - [켜자마자 일본어 (잠금화면 JLPT, JPT+공부알람)](https://chrome-stats.com/d/net.dayword.jpkr) — 576,908 users, 3.55 / 5 - [WordBit Japanese (Alarm)](https://chrome-stats.com/d/net.wordbit.jpen) — 122,729 users, 3.78 / 5 - [가벼운 일본어](https://chrome-stats.com/d/hoho.japan.dictionary) — 7 users - [WordBit Японский язык + Alarm](https://chrome-stats.com/d/net.wordbit.jpru) — 2,126 users - [WordBit Japonés (Alarma)](https://chrome-stats.com/d/net.wordbit.jpes) — 7,098 users, 5.00 / 5 - [WordBit Japonês + Alarm](https://chrome-stats.com/d/net.wordbit.jppt) — 165 users - [WordBit Bahasa Jepang + Alarm](https://chrome-stats.com/d/net.wordbit.jpid) — 6,419 users - [WordBit 日語 (鎖屏自動學習) -繁體](https://chrome-stats.com/d/net.wordbit.jptw) — 36,068 users - [WordBit ภาษาญี่ปุ่น + Alarm](https://chrome-stats.com/d/net.wordbit.jpth) — 5,247 users - [WordBit जापानी + Alarm](https://chrome-stats.com/d/net.wordbit.jpne) — 61 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.locklearn)
