01
Open your usual apps
When you try to open blocked apps like social media, LEXA's shield steps in to pause you.
iPhone App
Turn scrolling into learning
That moment when you reach for an app is your best time to review. LEXA is a new kind of Japanese learning app that combines an app blocker with an advanced memory algorithm.
No tedious registration. All learning data is safely stored only on your device.
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.
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.
Start without an account
Use the ordinary learning features without registration. Optional Cloud Backup can restore your cards and learning data.
Your data is local by default
Apple's Screen Time feature is used strictly for blocking apps. We never monitor your browsing history. Learning data is stored locally by default; optional Cloud Backup stores only data needed for restoration.
Make your next impulse a review session.
LEXA is currently in development exclusively for iPhone.
