## What is WordDeck?

You learned that word yesterday. Today? Blank.

WordDeck is a flashcard app that makes things stick — designed for adults with no time to waste.
No ads. No clutter. Just focus.

• Smart scheduling
Cards show up right when you're about to forget. Less cramming, more retaining.
• Quick & flexible
Tap through cards at your own pace. Works both ways — front-to-back or back-to-front.
• Made for grown-ups
A calm, clean interface. No streaks to protect, no coins to collect.
• Widget review
Study right from your home screen without opening the app.
• 5 minutes a day
Short sessions that actually add up over time.

Who it's for:
• Picking up a new language
• Prepping for an exam
• Tried flashcard apps before and quit
• Want results, not rewards
Five minutes. Every day. That's it.
