Shuffle by Future Friends

Learn the NATO phonetic alphabet, world capitals, or periodic table elements. Or create your own flashcard decks.

Shuffle is a flashcard app that adapts to you. Cards you struggle with appear more often. Cards you know well fade into the background.

No due dates, no guilt - just review what needs attention most.

Built-in decks:

• NATO Phonetic Alphabet (Sierra, Tango, Uniform...)
• World Capitals (195 countries)
• Element Symbols (Periodic table)

How it works:

• Rate each card Easy, Okay, or Meh
• Easy cards show up less often
• Meh cards show up more often
• That's it

Create your own decks and cards directly on your phone.

Shuffle uses a priority-weighted system instead of strict spaced repetition. Miss a day? No problem. Cards don't pile up punitively. Shuffle's not a guilt machine.

Need advanced scheduling, media cards, and endless customisation? Anki is brilliant. Shuffle is for when you want something super simple.
