Is Tomaru better than Anki for learning vocabulary?
For language vocabulary, Tomaru is the better choice: it uses the same FSRS algorithm but comes with curated exam decks, has FSRS on from the start, works out your daily load from your exam date, and is free on iPhone. Choose Anki if you're studying non-language subjects, want custom card templates or add-ons, or need to work fully offline.

Key points
- Tomaru and Anki both use the open-source FSRS algorithm to schedule reviews.
- Tomaru uses FSRS from the start, while Anki still defaults to SM-2 and you have to turn on FSRS yourself at the bottom of the deck options.
- Tomaru includes 243 public decks where every card has an example sentence and its translation, while Anki has no official decks and its shared decks aren't reviewed.
- Tomaru is free on both iPhone and Android, while Anki's iPhone app, AnkiMobile, is a US$24.99 one-time purchase.
- Tomaru can import your Anki decks and review history from Settings on tomaruai.app in a desktop browser.

Why choose Tomaru for language vocabulary?
Anki solves the question of when to review. Learning language vocabulary raises three more problems, and Tomaru handles all of them for you:
- Where the cards come from: Tomaru's decks are already built, so you don't spend hours hunting for decks and checking for typos.
- How much to learn each day: Tomaru uses your exam date and your past answer speed to calculate your daily new words and approximate study time.
- How to make words stick: the back of each Tomaru card breaks down words and sentences and shows readings, and you also get an AI dictionary and sentence corrections.

When should you choose Anki?
- You're studying non-language subjects like medicine, law, or programming.
- You want to design your own HTML/CSS card templates or use Anki add-ons.
- You need to work fully offline.
