Anki is the undisputed king of spaced repetition. With AnKing's 40,000+ card deck and a decade of community content, it's the default choice for preclinical years. But "default" and "best" aren't the same thing.
Onky takes a different angle: audio-first cards, 30-second micro-reviews, and full Anki import. It's not trying to replace Anki's content library. It's trying to make your existing knowledge accessible when you're commuting, on rounds, or at the gym — places where you can't stare at a screen.
So which is right for you? It depends on what year you're in and how you actually study. Let's go through it category by category.

Category Breakdown
Content Volume: Anki wins
There's no sugarcoating this one. AnKing has 40,000+ pre-made, peer-reviewed cards covering the entire preclinical curriculum. It took the community years to build. Onky is growing its medical library, but it's not there yet for M1/M2 volume coverage.
The good news: you can import your AnKing deck directly into Onky and get the audio benefits on top of AnKing's content. More on that in the verdict.
Audio & Hands-Free Studying: Onky wins
This is the core reason Onky exists. Every card reads aloud via high-quality TTS (6 voice options including British accents), supports hands-free review mode, and works with your AirPods' playback controls.
Anki wasn't built for audio. You can technically add audio files to cards, but there's no native hands-free mode. You need add-ons, manual recording, or third-party workarounds to get anywhere close to what Onky does natively.
Why Audio Matters More in Y3/Y4
Preclinical years = desk time. You're in lecture halls, at a library desk, reviewing at home. A screen is always nearby.
Clinical rotations flip this completely. You're on your feet 10+ hours a day. Your commute is your only real study window. That's exactly where audio-first studying pays off — and where Anki's design breaks down.
Review Burden: Onky wins
The most common complaint about Anki among med students: the review mountain. Get behind by one week and you're staring at 700+ reviews with no end in sight. Many students abandon their decks entirely.
Onky uses 30-second micro-cards — short, focused, and designed to fit in dead time. The daily review load stays manageable because the cards are designed to be consumed quickly. You don't need a 2-hour block; 20 minutes on a commute gets you through a solid session.
Price: Both free / freemium
AnkiDroid (Android) is free. Anki desktop is free. AnkiMobile (iOS) costs $25 — a one-time purchase that students often call the best $25 they spent in med school.
Onky is free to start, no account required. Just open the app and study. Import your Anki deck in 30 seconds.
Clinical Focus: Onky wins
Onky's card library is curated specifically for clinical rotations — the scenarios you face in Y3 and Y4. Anki's community content skews heavily preclinical because that's where the community is largest.
For Step 1 and Step 2 prep, both tools can work. But for keeping sharp during busy rotations without a 2-hour study block, Onky fits the lifestyle better.
Community & Ecosystem: Anki wins
Anki has a decade of community support: AnKing, r/medicalschoolanki, 500+ add-ons, YouTube tutorials, Reddit threads for every question you'll ever have. It's a mature ecosystem that's been tested by hundreds of thousands of students.
Onky is newer. The community is growing. If you rely on community-created content and peer support for your deck strategy, Anki's ecosystem is unmatched.
Import: Tie
You can import your Anki .apkg decks directly into Onky — the whole thing, not just some cards. This is intentional: we didn't want students to choose between their existing content and audio-first reviewing.
The Verdict
Our Honest Take
Use Anki for M1/M2 volume. AnKing is irreplaceable for preclinical prep. The community, the content depth, the add-ons — nothing matches it for building your foundational knowledge base.
Use Onky for commutes, clinical years, and audio. Once you're on rotations, screen time collapses and commute time becomes your primary study window. That's where Onky was built to live.
Import your Anki decks to get both. You don't have to choose. Import your AnKing deck into Onky and review it hands-free on your commute — all the content, none of the screen.

Who Should Switch to Onky?
- M3/M4 students buried in rotations with no desk time to spare
- Any student with a commute — 30+ minutes one way is significant study time
- Students with Anki burnout — if the daily review pile is killing your motivation, shorter micro-cards help
- Gym, walking, cooking studiers — if you study during physical activity, audio-first is the only viable option
Who Should Stick with Anki?
- M1/M2 students in heavy content-acquisition mode — AnKing's depth is unbeatable
- Students who rely on community decks for their entire curriculum
- Desktop-first studiers who do all their reviewing at a desk
- Students who've built years of Anki history they don't want to lose
Note: you don't have to fully switch to benefit from Onky. Most students who use Onky still keep Anki for their desktop sessions and use Onky specifically for commutes and clinical years.
