Duetoday is the best at building the deck.
Anki's spaced repetition algorithm is legendary. But Anki requires you to write every card yourself — which takes hours. Duetoday generates a complete deck from your notes, PDFs, or YouTube in seconds, so you can spend that time actually studying.

Being honest
Where Anki genuinely
pulls ahead
The most mature SRS algorithm
Anki's SM-2 based algorithm has been refined over decades and is trusted by medical students, language learners, and serious memorisers worldwide. If you need surgical precision in your review scheduling, Anki is the benchmark.
Infinite customisation
Custom card types, HTML/CSS styling, LaTeX for maths, thousands of add-ons, and granular deck settings. Anki can be configured exactly to your workflow in a way no other app matches.

You need maximum control over your SRS algorithm and card formatting. You're studying for a high-stakes certification (e.g. USMLE) where community decks like AnKing are essential. You're a power user who wants an add-on ecosystem and prefers to work fully offline.
