## What is LockToLearn?

LockToLearn turns the moments you'd spend scrolling into moments you spend learning.
Lock the apps that distract you. When you try to open one, review a few flashcards first — then it opens. No guilt, no fines. Just a small habit: learn a little before you scroll.

LEARN A LANGUAGE
• Pick a language and a level, and AI builds a vocab deck for you in seconds.
• Levels for CEFR (A1–C2), TOEIC, Eiken (Japan), JLPT, DELE, TOEFL and IELTS.
• Every card comes with an example sentence and its translation.

LEARN ANYTHING
• Paste a list from Notes, Excel, Google Sheets or ChatGPT — one line per card.
• Or import a CSV file for longer lists.
• Certifications, school subjects, work terms: make decks for whatever you're studying.

HOW IT WORKS
• Choose the apps you want to use less.
• Try to open one, and a few flashcards appear.
• Recall the answer, flip the card, and mark whether you remembered it.
• Finish the review, and the app unlocks.

STAY HONEST WITH STRICT MODE
• Miss the same card twice, and that round doesn't unlock. Try again after a short break.
• Adjust how long each card stays on screen and how long the break lasts.

TRACK YOUR PROGRESS
• See how many cards you've reviewed, your streak, and the moments you turned into study time.

FREE AND PREMIUM
• Free: lock one app, save up to 15 decks, create vocab decks, paste lists and import CSV files.
• Premium: lock multiple apps at once, and save unlimited decks.
• Emergency keys let you lift a lock when you're truly stuck.

Light and dark mode supported.
