Most students have 2–3 hours/day of “dead time” (walking, commuting, waiting, chores). ZenCards turns that into review time — without sacrificing your life.
Extra hours each day can mean a part-time (or even full-time) job, more time with friends/family, or committing fully to a sport or club.
Hearing information and saying answers out loud boosts recall (often called the production effect). Seeing + hearing together supports dual coding so the same study time goes further.
ZenCards schedules reviews so you see cards again right before you forget — the core idea behind spaced repetition. You waste less time re-studying what you already know.
Better retention can translate to better exam performance — helping you compete for internships, grad school admissions, and stronger early-career opportunities.
Study in the car (passenger), walking to class, at the gym between sets, running errands, or between lectures. If you can listen, you can review.
Create decks, add questions + answers, or import from Anki. (You can also include images + math.)
ZenCards supports multiple hands-free behaviors:
After you see the answer, you rate it: Again / Hard / Good / Easy. ZenCards uses that rating to schedule when you see it next.

Spaced repetition is a study method where you review information at increasing intervals, timed around when you’re most likely to forget. It’s designed to maximize long-term retention while minimizing wasted review time.
In simple terms: memory is stronger when you engage multiple channels. Speaking responses out loud can reinforce recall (often referred to as the production effect), and combining visual + audio supports dual coding — giving your brain more “handles” to retrieve the info later.
