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.
