Is Anki free? What it costs on each device

Yes, almost everywhere. Anki is free on Windows, Mac and Linux, AnkiDroid is free on Android, and AnkiWeb, the sync service with a study page in the browser, is free too. The one paid version is AnkiMobile for iPhone and iPad, a one-time purchase of $24.99 in the US. There's no subscription and no ads in any of them, and that didn't change when AnkiHub took over running Anki in 2026.

What each version costs

Checked October 2026.

Shared decks on AnkiWeb are free, and so are add-ons, which only run in the desktop app.

Is Anki still free after AnkiHub took over?

Yes. On February 2, 2026, Anki's creator, Damien Elmes, announced on the Anki forums that he would gradually hand Anki's business operations and open-source stewardship to AnkiHub, the company behind the shared-deck platform of the same name, while staying involved himself. Two days later he listed what stays the same: "zero planned changes to the revenue model". The computer version stays free and open source, syncing stays free, paid for by sales of the iOS app, and AnkiMobile stays a one-time purchase of $25 US.

AnkiHub's own plans are a separate thing: a free tier plus paid subscriptions for shared decks that a team keeps up to date, such as medical school decks, and for AI study tools. They add to Anki; you don't need one to use it.

Why the iPhone app costs money

Anki's own site says that AnkiMobile is the official iOS app and that its sales fund Anki's development. It's how a free desktop app with no ads pays for itself. AnkiDroid is a separate open-source project run by contributors and funded by donations, which is why it's free.

Free ways to use Anki on an iPhone

• AnkiWeb in Safari. Sign in at ankiweb.net and you can review your cards in the browser for free. It works, but it's a website, so it's best for reviewing cards you made on a computer.
• Amgi, an unofficial open-source port. Amgi is a volunteer project, started in March 2026, that runs Anki's own engine in an iPhone app and can sync with AnkiWeb. It isn't on the App Store and isn't made by the Anki team: its GitHub page offers an unsigned app file, so you have to sideload it, signing and installing it yourself from a computer. It's an early project (version 0.2 in September 2026), so back up your collection before you sync it.
• Pay once for AnkiMobile. If you already use Anki on a computer, $24.99 once is usually worth it, and it syncs with your desktop through AnkiWeb.
• Use a different app. Spaced repetition on iPhone compares the options.

Apps that aren't Anki

Several App Store apps have "Anki" in their name or description without being part of Anki. AnkiApp, for example, is a separate app from a different company. The official ones are the four in the table above, all linked from apps.ankiweb.net. Amgi, above, uses Anki's code but is a separate, unofficial project.

Where Decks fits

Decks is a separate iPhone app, not made by the Anki team. It's free to download, uses SM-2 (the algorithm Anki's original scheduler is based on) with the same four buttons, and comes with ready-made language decks. The free plan has a daily review limit; Premium lets you set your own. It can't open Anki decks, so if you already have Anki decks, AnkiMobile or AnkiWeb is the better route.
