Spaced. vs K Flash

Remember what you learn, one card at a time. Spaced. is a minimalist flashcard app for iPhone and iPad. Create decks for languages, classes, trivia, lyrics, work concepts, or anything else you want to keep in memory. Review with spaced repetition, and Spaced. brings each card back when it matters most. Why Spaced.? • Study less, remember more Cards you know well come back later. Cards you miss return sooner. Your sessions stay focused on what needs attention. • Simple, fast reviews Flip a card, recall the answer, then swipe right if you remembered or left if you missed it. No clutter, streak pressure, or complicated setup. • Make the decks you actually need Create your own collections, decks, and cards with text, images, and audio. Reorder things, search decks, and track progress per deck. • AI-assisted deck creation Use an AI assistant you already have to draft a deck. Paste the JSON into Spaced., review the cards, and add it to your library. Spaced. does not run AI inference or require an AI account. • Starter decks included Begin with built-in French, Indonesian, and Japanese decks, including Japanese kana with pronunciation audio. • Private by design No ads. No tracking. No Spaced. account. Your user-created decks and progress stay on your device and can sync through your private iCloud account. Spaced. is free to use, with optional one-time tips for people who want to support development.
