Flashside is the flashcard app that remembers for you. Make cards for anything — vocabulary, kanji, anatomy, exam questions — and Flashside's spaced repetition schedules each one at exactly the moment you're about to forget it. A few focused minutes a day beat hours of cramming.

EVERYTHING ON YOUR DEVICE
Your cards, collections and progress live on your phone. Study on a plane, in the subway, off the grid — no account, no connection, no waiting. Sync and sharing are there when you want them, never required.

SMART REVIEWS, ZERO PLANNING
• One "Today" queue collects everything due across all your collections
• Grade each answer — Again, Hard, Good, Easy — and the schedule adapts to you
• Struggling cards get flagged so you can rewrite them instead of grinding them
• Optional gentle reminders so a streak never slips away

CARDS THE WAY YOU THINK
