Affex vs. Noji: Which Modern Flashcard App is Better in 2026?

Both apps look good. Both use spaced repetition. One hits you with a paywall when you need it most—the night before an exam. That’s the entire difference, and it matters.

🔍 What Each App Actually Does

Noji: Modern Design, Freemium Ceiling

Noji is a clean, well-designed flashcard app with multiple review modes (standard SRS, multiple-choice, type-the-answer), streak tracking, and a mobile-first interface. The UI is polished. The experience feels modern.

The ceiling: Free users hit a daily learning limit. Once you exceed a set number of new cards or reviews per day, Noji stops and asks you to upgrade. Unlimited daily reviews, rich text editing, and custom SRS presets all require a paid Premium subscription.

Affex: No Limits, No Tiers

Affex ships the same feature set to every user. No daily caps. No locked formatting tools. No SRS presets hidden behind a subscription.

It also extends beyond flashcards: Structured Courses, a built-in Pomodoro timer, global leaderboards, and native Anki .apkg import are standard. All free. On every platform.

🏆 Three Decisive Wins for Affex

1. No Daily Cap. Ever.

Noji’s free daily limit is the most-cited frustration in user reviews. You have 400 cards due before an exam. You hit the cap at card 200. Now you’re choosing between paying or switching apps mid-session.

Affex has no daily limit. Review 50 cards or 5,000. The app doesn’t care. You’re never blocked.

2. Rich Text is Free—Including KaTeX Math

Noji locks rich text formatting behind Premium. That’s a problem for medical students, engineers, or anyone whose flashcards need more than plain text.

Affex gives every user TipTap rich text editor, Markdown support, and KaTeX math rendering—the same engine used by major academic platforms—for free. Build cards with chemical structures, equations, or formatted code blocks. No extra charge.

3. Native Anki Import That Actually Works

Many Noji users come from Anki. Migrating 5,000-card decks with embedded images and custom note templates often breaks in Noji’s importer.

Affex’s importer is built in Rust and handles .apkg files natively. Drop in the AnKing deck (the community-maintained USMLE .apkg). Every card, image, audio file, and note type converts correctly. Start reviewing in under two minutes.

🛡️ Two Areas Where Noji Still Wins

1. Multiple Review Modes

Noji offers more variety: standard flip-the-card, multiple-choice generation, and type-the-answer mode. If traditional flashcard formats feel monotonous, Noji’s review variety helps. Affex is adding variety modes—but today, Noji wins on this dimension.

2. The Cram Algorithm

Noji’s “General” algorithm cycles through all cards consecutively, ignoring SRS intervals. It’s designed for last-minute cramming. If you skipped your reviews for a week and have an exam tomorrow, this mode is genuinely useful. Affex lets you adjust deck limits manually, but doesn’t ship a dedicated cram mode.
