## Description

A scientific algorithm adapts your review schedule to your memory — automatically. Start today.

Spaced is a flashcard app that uses spaced repetition to help you memorize words, phrases, and knowledge efficiently for the long term.

KEY FEATURES

◆ FSRS Algorithm
The world-leading memory model "FSRS" analyzes your retention in real time and suggests reviews only when you're about to forget — maximizing results in minimum time.

◆ Auto Dictionary Lookup (Multilingual)
Just type a word and tap the dictionary button — pronunciation, meanings, and examples are filled in automatically. Displayed in your device language: Japanese, Korean, Chinese, Spanish, French, German, Portuguese, or English.

◆ Text-to-Speech
Tap any word or example sentence to hear native pronunciation. Build your listening skills at the same time.

◆ Organize with Decks
Create decks by topic — English vocab, certifications, technical terms — and focus on exactly what you want to study.

◆ Simple to Use
Front side for the question, back for the answer. Flip the card and rate yourself: Again / Hard / Good / Easy. Your rating determines when you'll see the card next.

◆ Track Your Progress
Monitor retention rate, review count, and study streak on your dashboard. See your daily progress at a glance.

◆ Passwordless Login
Sign in securely with just your email and a one-time code. Cards sync automatically across all your devices.

• Students studying for medical, legal, or IT certifications
• Anyone building vocabulary in a foreign language
