The 8 Best Flashcard Apps in 2026 (Compared)

The best flashcard app in 2026 mostly depends on one question: who writes the cards? If you want them created for you from your classes, Hekko. If you write them yourself and want the most powerful spaced repetition, Anki, free on desktop and Android. To find ready-made cards, Quizlet or Knowt. To write your cards directly inside your notes, RemNote. And for simple spaced repetition, Brainscape or Mochi.

Full disclosure: Hekko is our product. That's exactly why every price below comes from each tool's own pricing page, and why every app, Hekko included, gets its limitations listed.

TL;DR

The honest answer for 2026: making good cards takes time, and that's where most students give up. If that's you, let an app create them from your classes (Hekko). If you enjoy making your cards and have thousands to learn, nothing beats Anki.

• Best for creating flashcards from your classes: Hekko
• Best spaced repetition: Anki
• Biggest card library: Quizlet
• Best free Quizlet-style app: Knowt
• Best for writing cards inside your notes: RemNote
• Easiest for beginners: Brainscape

What makes a good flashcard app?

A good flashcard app does two things: it helps you get good cards, and it shows them to you at the right time. Spaced repetition, which shows you a card just before you forget it, is what separates flashcards that work from a deck you flip through on a loop (see studying with flashcards).

To compare, look at:

• Creation: by hand, imported, or generated from your classes?
• Card quality: one idea per card, a precise question?
• Scheduling: card-by-card spaced repetition, or review by deck?
• Devices: is the app on your phone, for free?

The 8 apps, one by one

1. Hekko: best for creating flashcards from your classes

Hekko removes the step everyone puts off: writing the cards.

Should you make your own flashcards or generate them?

Writing your cards helps you understand, but it takes time, and many students never make enough of them. Generating cards from your lecture saves you that time; what matters is to go over them, fix or delete the ones that don't help, and add your own on the hard parts. The real gain comes from reviewing, not from making (see making revision flashcards).

Which free flashcard app should you choose?

Anki on desktop and Android, Knowt everywhere, Brainscape to get started, Mochi offline. To generate cards from your classes, Hekko gives you 2 full courses a month.

How many flashcards should you review per day?

Start small: 20 to 30 new cards a day is enough, because each new card comes back several times over the following days. A short session every day beats a weekend marathon.

How do you choose the right one?

1. You don't have time to make your cards → Hekko
2. You have thousands of cards to learn → Anki
3. You're looking for ready-made cards → Quizlet, or Knowt for free
4. You take your notes on a keyboard → RemNote
5. You're a beginner → Brainscape
6. You want simple and offline → Mochi
7. You need a game element to get started → Gizmo
