Turn 'just checking' into learning time

LEXA is more than just an app blocker. It's a new system that uses your unconscious urge to open social media to build a learning habit.

01

Open your usual apps

When you try to open blocked apps like social media, LEXA's shield steps in to pause you.

02

Quick review

Take a quick Japanese vocabulary quiz to unlock the app. Review words you're about to forget at the perfect time.

03

Enjoy guilt-free

Clear the quiz for 15 minutes of free access. Enjoy your app guilt-free knowing you've done your learning.

App blocker and learning app, all in one

Advanced memory algorithm

Based on the forgetting curve, it prioritizes the words you are most likely to forget.

Self-study in spare time

Study at your own pace like a normal flashcard app, even on days you don't open social media.

Streaks to keep you going

Visualize your daily achievements. The urge to open apps turns directly into motivation to continue.

No account required

All data is saved on your device. Start immediately with no tedious registration process.

Your data stays on your phone

Apple's Screen Time feature is used strictly for blocking apps. We never monitor your browsing history. All learning data is stored locally on your device and never sent externally.
