Best Anki Alternatives in 2026: 5 Spaced Repetition Apps Compared

Published on 2026-07-28 • 9 min read • App Reviews

Anki is powerful, but it is not for everyone. We compare the best Anki alternatives for 2026 — including Uben — across ease of use, multi-subject support, and spaced repetition quality.

Why Look for an Anki Alternative?

Anki is the gold standard for flashcards, but its interface feels dated, its default scheduling (SM-2) is less adaptive than modern FSRS, and set-up takes real effort. Many learners want a tool that is beautiful out of the box, works on any subject, and still delivers the spaced repetition magic. That is exactly the gap alternatives are filling in 2026.

What to Look for in a Spaced Repetition App

The best apps combine three things: a modern algorithm (FSRS is now the benchmark), an interface that makes daily review a habit instead of a chore, and flexibility to study more than one subject. Bonus points for importing Anki decks, so you are never locked in, and for export options that let you study on other devices.

Uben: The Free, Modern All-Subject Alternative

Uben is a free, browser-based spaced repetition platform built for any subject — languages, sciences, coding, history, art, trivia, and more. You get FSRS scheduling, custom deck creation, and one-click Anki .apkg import (supporting 12+ languages). A standout feature is KAnki export, which turns your decks into a config you can study offline on a jailbroken Kindle.

How Uben Compares on the Basics

For ease of use, Uben beats Anki hands down — you sign up and are studying in minutes. For scheduling, both can run FSRS, but Uben's adaptive review queue requires zero configuration. For import, Anki is the source and Uben is one of the few alternatives that accepts .apkg files directly. And because it is free with no paywalls, the only cost is your daily review time.

Making the Switch

Switching is easy: export your decks from Anki, import them into Uben, and set a daily goal. Your review history resets, but FSRS will quickly re-learn your true mastery level from your first few sessions. Start with your smallest deck to test the workflow, then migrate the rest.
