How FindingFundaa uses spaced repetition (without you noticing)

Most quiz apps treat each question as one-and-done. You answer, you move on, the question disappears forever. Whether you got it right or wrong is irrelevant after that swipe.

That's a waste.

The forgetting curve

In 1885 a German psychologist named Hermann Ebbinghaus did the most boring experiment in history: he memorized lists of nonsense syllables and tracked how fast he forgot them.

He found something useful: forgetting isn't linear. You lose ~40% of new information within an hour, ~60% within a day, then the curve flattens. The good news — every time you re-encounter the information just before you would have forgotten it, the curve resets and stretches further next time.

This is the basis of every flashcard app you've ever used. Anki, Memrise, Quizlet — all built on spaced repetition.

What we built

FindingFundaa quietly schedules every question you've ever answered.

• Got it wrong? It comes back tomorrow. If you get it right then, in 4 days. Then 10. Then a month.
• Got it right first try? Same schedule but starting longer. We're not trying to drown you in repeats.
• Mix ratio: ~20% of your daily feed is spaced reviews. The rest is fresh questions tuned to genres you like.

You don't see flashcards. You don't see "review mode." There's no separate study screen. The reviews just show up in the normal feed at the right moment.

What that feels like

The first time you re-encounter a question you got wrong a week ago, two things happen:

1. You probably get it right this time. The information clicked back into place.
2. You feel slightly smarter. Wait, I knew this.

That feeling is the entire point. Most "learning" apps are stressful — they remind you of how much you don't know. Spaced repetition is different. It reminds you of what you've quietly mastered without trying.

How it works under the hood

We use a simplified SuperMemo SM-2 schedule with three knobs per question:

• Ease factor — how cleanly you've remembered this. Drifts up on hits, down on misses.
• Interval — how many days until next review.
• Repetitions — consecutive correct streak. Reset on miss.

When you answer:

correct  → interval = round(prev_interval * ease_factor)
wrong    → interval = 1 day, ease_factor reduced

That's literally it. Forty lines of code, and your trivia app starts feeling like a personal tutor.

Why this matters

If you use FindingFundaa for a year, you won't just have answered some questions. You'll have learned the answers — in a real, durable way. The 100 questions you saw repeatedly will sit in your long-term memory the way pulled threads from a great book do.

That's a different value proposition than "watch this short video about a fun fact." We're not trying to give you dopamine. We're trying to give you the kind of knowledge you actually keep.
