DeveloperCards
Every pull is earned. Every pull is new.
DeveloperCards: spaced-repetition flashcards for developers where card packs are earned by studying, never bought, and never deal a duplicate. 81 C# / .NET + 154 AWS SAA-C03 cards, free, iOS.
Prepping a .NET interview or the AWS SAA-C03? DeveloperCards turns the prep into a collection you build by showing up. The loop in one sentence: learn a new card, earn a pull, rip a pack, and what you draw becomes what you study.
WHAT'S INSIDE
Two free decks, both in English:
- C# / .NET — 81 interview cards, fundamentals to intermediate (async/await, boxing, controllers, OOP and more) with a C# code snippet on essentially every card.
- AWS Associate Architect — 154 scenario-style SAA-C03 cards (S3 storage classes, ElastiCache Multi-AZ, IAM, Lambda and more) with a real-world usage note on nearly every card.
Every card is a question with a written explanation. Rarity is difficulty: Common, Rare and Legendary map to how hard the question is, so a Legendary is one of the hardest questions in the deck.
HOW PULLS WORK
- Pulls are earned, never sold. Learn a new card, earn a pull: the first time you rate a card Hard, Good or Easy, one pull lands in your wallet, no claim button. Clearing everything due for the day adds one more, once a day. New players start with 3 pulls, so the first pack opens in seconds.
- Never a duplicate. The draw pool is only the cards missing from your collection.
- Pity: after 10 Commons in a row, the next card is Rare or better, as long as an unowned Rare or Legendary is still in the pack.
- Open 1 or Open 10. You are only charged for cards you actually receive.
- Your wallet holds up to 60 pulls plus a 5-pull reserve. If you ever have nothing left to study and no pulls, you get 1 pull a day.
- Every draw is seeded and replayable, so the app can show why you got what you got.
- Rip the foil, watch the cards drop, tap to flip. Rare and Legendary reveals get their own sound and haptics.
HOW STUDY WORKS
Rate each card Again / Hard / Good / Easy. Cards return on a 7-stage ladder of 1, 2, 4, 8, 15, 30 and 60 days; a card is Mastered once it reaches the 15-day stage. Reviewing a single card keeps your streak alive. Streaks and milestones are tracked; the Library shows each card as New, Learning or Mastered.
FROM ONE DEVELOPER
DeveloperCards is an indie project: one person built the app and the backend and writes or edits every card by hand. Both decks are free. A monthly Premium subscription exists for future premium decks, but there is nothing premium to unlock yet. Next up: more decks. Feedback is welcome.
