About this app

Never forget anything.

Most spaced repetition and memory apps lock you into flashcard decks. Ebbio doesn’t. Add anything you want to remember — a fact, a formula, a vocabulary word, a phrase, a concept, or a step in a recipe — and Ebbio decides when you should review it next, using FSRS, a modern scheduling algorithm trusted by advanced Anki users.

OPEN ONCE A DAY

Ebbio shows you exactly what to review today. Nothing more, nothing less. No decision fatigue, no guessing what’s “due.” Just open, review, and close. Make studying, memorization, and daily learning part of your routine without spending time planning what to study.

POWERED BY THE FORGETTING CURVE

Every item has its own memory curve, calculated from your real review history. Ebbio tracks your recall probability over time and schedules your next review right before you’d forget — not too early (wasted effort), not too late (relearning from scratch). This science-based approach helps you retain what you learn for longer.

NOT JUST FLASHCARDS

Organize anything with flexible Collections and Trees, like a textbook’s table of contents. Track “Chapter 3, Problem 6” or “Grammar Point 12” without building a rigid flashcard for each one. Great for studying, coursework, exam prep, test preparation, certification exams, language learning, vocabulary, and building your own personal knowledge base.

STUDYING FOR A TEST OR DEADLINE?

Set a goal date on any item or collection. Ebbio works backward from that date so your memory peaks exactly when you need it — for an exam, test, certification, presentation, interview, or other important deadline — instead of cramming the night before.

YOUR PACE, YOUR LIMITS

Choose a daily study limit by item count or by time. Ebbio automatically spreads your workload across the days ahead, so you never face a mountain of overdue reviews. Build a sustainable study habit without overwhelming yourself.

BUILT TO KEEP YOU CONSISTENT

Track your study streak, see the forgetting curve on every item, and check your learning progress with clear statistics and a calendar view. Turn daily review into a simple, consistent learning habit.

PRIVACY FIRST

Your data stays on your device. Encrypt it if you like (PBKDF2 + AES-256-GCM) and back it up on your own terms, as a plain or encrypted file. No accounts, no ads, no tracking — nothing is ever sent to a server.

ONE-TIME PURCHASE

Try Ebbio free with up to 35 items. Unlock everything with a single one-time purchase. No subscriptions, ever.

Whether you’re learning a language, studying vocabulary, preparing for an exam or certification, memorizing a speech, learning for school, or simply trying to remember one new thing a day, Ebbio adapts to what you’re learning, not the other way around.
