Is Noji the same as AnkiPro?

Yes. Noji announced the rename from AnkiPro on 2 June 2025; according to Noji, the product remained the same. According to the Anki FAQ, Noji has nothing to do with Anki; they are separate developer teams.

What does Noji Premium cost?

The German App Store lists several options, including one month for 4.99 €, annual plans for 29.99 €, 44.99 € and 89.99 €, and lifetime for 79.99 €. The store page does not explain which price you see as a new customer.

Can I get Noji decks back to Anki or into checkst?

Only to a limited extent. According to the help, Noji exports CSV and its own OFC format, not .apkg, and imported or duplicated decks cannot be exported at all. You can take decks you created yourself along as CSV, but without images.

Can I use Noji for free?

Yes, but with a maximum of 50 cards per day. Images, offline study and AI features belong to Premium according to Noji.

checkst vs. Noji (formerly AnkiPro): an honest comparison

Let's start with the elephant in the room: Noji was called AnkiPro until mid-2025 and has nothing to do with Anki. The official Anki FAQ lists the app on its page under "Anki knockoffs" and states that both products come from separate developer teams. So if you searched for "Anki for iPhone" and installed AnkiPro, you did not get Anki. On Reddit, someone describes exactly that: "I thought I downloaded anki", and a subscription followed.

That alone doesn't make Noji a bad app. So let's look at what it can do.

Status: November 2026. All information about Noji comes from the sources linked below.

Where the name comes from

Anki developer Damien Elmes already criticized on 31 July 2021 in the Anki forum that the name and presentation of AnkiPro were misleading. His argument: competing under your own name is perfectly fine, but a competing "Anki" product endangers the funding that runs through AnkiMobile. On 2 June 2025, the manufacturer then announced the rename to Noji. Noji does not cite a legal dispute as the reason, and no court ruling is known.

A small detail for people who like to know who they're dealing with: the App Store names DELIGHTHUB PTE. LTD. from Singapore as the provider, while the privacy policy and terms of use name Vedas Apps Ltd from England and Wales. How the two are connected is nowhere stated.

Where Noji is ahead

More platforms. Noji runs on iPhone, iPad, Android and in the browser. If your study group is mixed or you want to create cards on your laptop, that is a real advantage. checkst is an iOS-only app.

Working on one deck together. Noji's live collaboration is concrete: share a deck via link, invite people as viewers or editors, and changes land automatically for everyone. In checkst you share decks within a study group; Noji offers more sophisticated simultaneous editing with roles.

Lifetime option. If you hate subscriptions, according to the App Store listing you can buy Premium Lifetime from Noji for 79.99 €. checkst Pro is only available as a subscription.

Presets instead of dials. Noji offers predefined learning modes for languages and medicine. That takes decisions off your hands; whether it schedules better than FSRS is nowhere documented.

Where checkst is ahead

No daily limit. Noji Free stops you at 50 cards per day. That sounds like a lot until you have an imported medical deck in front of you and the due reviews pile up. In checkst you study without a limit; Pro brings sync via your checkst account, not the right to review your own cards.

Offline without the fine print. At Noji, offline study is a Premium feature, and even then, according to the help pages, limits apply: at most 6 decks with 200 cards each, decks must be downloaded in advance, and you cannot add or edit cards offline. checkst stores your decks locally on the iPhone. Subway, airplane mode, lecture hall with dead Wi-Fi: no problem.

You can get out again. This is the point you should know before switching. Noji imports .apkg but does not export .apkg; it exports CSV (without images and image occlusion) or its own OFC format. And according to the export help, you can only export decks you created yourself, not imported or duplicated ones. So if you import an Anki deck into Noji, study there for months and then want to leave, you have a problem. For the way back, the Anki FAQ points to an external add-on called Copycat Importer. checkst exports .apkg, Anki's own format.

FSRS, not maybe-FSRS. Noji's own comparison page names SM-2. A blog article mentions FSRS, but no setting for it is documented. checkst schedules with FSRS. It's also important to know: according to Noji's help, switching the learning algorithm resets your learning progress.

AI without upload. Noji's AI features (cards from topics, PDFs, cloze text) are Premium, and according to the privacy policy, AI inputs can go to OpenAI or Google. checkst generates cards by default directly on the device via Apple's Foundation Models. A personal OpenAI key is optional, not required.

Tracking. Noji's App Store privacy label states that usage data may be used for tracking. According to the privacy policy, data mostly goes to the USA. You don't need to know more than that to have an opinion.

Prices: complicated

The German App Store simultaneously lists several purchase options for Noji: one month for 4.99 €, 7.49 € or 19.99 €, annual plans for 29.99 €, 44.99 € or 89.99 €, lifetime for 79.99 €. The store page does not explain which price new customers actually see. So look carefully at which option is offered to you before buying.

checkst Pro costs 4.99 EUR for six months and renews automatically until you cancel. The core features cost nothing.

Moving from Noji to checkst

Honestly: bumpy. You can export decks you created yourself in Noji as CSV and then rebuild them, but you have to re-insert images yourself. For decks you originally imported from Anki, the quickest route is usually the old .apkg file, if you still have it. You open it directly with checkst.

Conclusion

Noji fits if you study on Android or in the browser, want to edit a deck live with others, or prefer a lifetime purchase over a subscription.
checkst fits if you study on iPhone or iPad, want to study offline and without a daily limit, want FSRS, and want to be able to take your decks with you as .apkg at any time.
