Our verdict

Suits learners who need to retain large volumes of vocabulary or facts and will put time into setup. The interface is not beginner-first, the iOS app costs 24.99 USD, and since 2026 the project has been moving to AnkiHub's stewardship.

Best for: Medical or law students and exam candidates who must retain thousands of cards

Skip it if: Those who want ready-made lessons, learning paths and gamification

Pros

  • Desktop and AnkiDroid are free and open source (desktop under AGPL v3+)
  • FSRS scheduling since version 23.10, alongside SM-2
  • Cards support audio, images, video and MathJax; the website says decks of 100,000+ cards run fine

Cons

  • The iOS app costs 24.99 USD and still lacks add-ons
  • AnkiMobile is rated only 4.0/5 on the App Store
All pros and cons · Who is it for?

Skip it if

  • People who need add-ons on iPhone or iPad

Problems it solves

Experience & key features

Anki is a flashcard program that says it helps you spend more time on challenging material and less on what you already know. After each card you rate your recall, and Anki schedules the next review for when you are about to forget. According to Wikipedia it dates from 2006, and the desktop app is licensed under AGPL v3 or later.

Cards can hold audio, images, video and MathJax, layouts are customisable and add-ons can be installed. Since version 23.10 (31 October 2023) Anki includes an optional FSRS scheduler. The desktop app runs on Windows, macOS and Linux; AnkiDroid is a free community-built Android app; AnkiMobile is the official iOS app, and all sync through AnkiWeb.

Pricing and value

The desktop app, AnkiDroid and AnkiWeb sync are all free. AnkiMobile for iPhone and iPad is a one-time 24.99 USD purchase with no subscription. Notable limits are that add-ons do not run on iOS and some tasks, such as importing an existing collection, still go through the desktop app.

On 2 February 2026, Damien Elmes announced on the forum that he would gradually hand business operations and open-source stewardship to AnkiHub. The post commits to keeping Anki's core code open source with no pricing changes planned, and leaves a formal governance model to be defined later. Compared with Quizlet or Memrise, Anki is more a build-your-own, deeply tunable tool than a source of ready-made content.

Cancellation & refunds

The sources read describe no separate refund policy for AnkiMobile; purchases and refunds follow App Store rules.

Privacy

Per the AnkiWeb privacy policy, when syncing the service stores card content, media files and review history; it is not visible to other users by default, but support staff can see it when investigating problems. It may use review history and options (not card text or media) for statistics. Access logs, including IP addresses, are deleted after 1 month. Data is stored on servers in the EU and USA. The desktop app sends an anonymous ID and OS version when checking for updates. The policy does not mention end-to-end encryption. AnkiMobile's App Store privacy label lists email and user content as linked to the user and crash data as not linked. On Google Play, AnkiDroid declares that some data types, such as personal info and photos and videos, may be shared with third parties, with encryption in transit and the option to request deletion.

Review evidence & sources8

Scores

Ease of use
6.6
Why this score

The website says getting started is easy even though Anki supports complex workflows; newcomers still have to learn decks, note types and scheduling options. AnkiMobile is rated just 4.0/5.

Features
8.8
Why this score

Customisable scheduling including FSRS, rich media, add-ons, shared decks and free sync cover nearly everything a flashcard app needs. Held back because add-ons do not run on iOS.

Value for money
9.0
Why this score

Desktop and Android are free; only iOS is a one-time 24.99 USD with no subscription, where many flashcard apps charge monthly.

Performance
8.0
Why this score

The website says decks of 100,000+ cards are no problem and AnkiDroid scores 4.7/5; no independent benchmarks were found.

Support
7.2
Why this score

A manual, FAQs and a forum are available, and AnkiDroid has its own help page. Sources show no live chat or phone support.

Privacy & security
7.8
Why this score

Using the desktop app without sync keeps all data local, with no ads. Held back because synced data sits on EU/US servers, support staff can view it when troubleshooting, there is no end-to-end encryption, and AnkiDroid declares some data sharing with third parties.
