DecoEcho

DecoEcho is a flashcard study app built for serious students — middle school through university.

Built around a smart spaced-repetition engine that learns what you know and what you need to see again, DecoEcho fits the way real studying works. Cards you're shaky on come back fast. Cards you've nailed get pushed further out. Over time, you study less and remember more.

Free for everyone:

• Unlimited cards, decks, and subjects • Spaced-repetition study with simple "got it / missed it" grading • Two study modes: dating-app style swipe-to-grade, or type-the-answer • Two-side cards with text and images • Daily and lifetime study stats • Full dark mode • iCloud sync across your iPhone and iPad • Share a deck with a classmate — they import their own editable copy

DecoEcho Pro (one-time purchase, never expires):

• Wikipedia autofill — type a topic, get a clean summary on the back of the card • Auto-translation — for language decks, type once and DecoEcho fills in the translation in Spanish, French, German, Italian, Mandarin, Japanese, Korean, or Portuguese • Text-to-speech — hear cards read aloud in the correct native voice • Paste notes → flashcards — paste your notes or scan a photo, and DecoEcho generates the cards for you using on-device AI

Privacy you can actually trust.

DecoEcho has no servers. No ads. No accounts. No tracking. No analytics. We don't collect anything because there's nothing to collect. Your cards, decks, and study progress stay on your device and in your own private iCloud — accessible only to you.

Designed in a calm Miami Art Deco aesthetic, DecoEcho gets out of the way and lets you focus on what matters: actually learning the material.

Built for iPhone and iPad. Requires iOS 18 or later.
