MemBox is a spaced‑repetition flashcard app built for word‑for‑word memory of scriptures, quotes, prayers, names, and other texts you want to keep for years and decades. Under the hood it uses a fixed, color‑coded review path that drills new cards twice a day at first, then gradually spaces them out until they become “lifetime cards” you see about once a year.
A focused memorization app for verbatim recall of a smaller, precious set of cards you want for life.
Every card follows one fixed, color‑coded path from Red to Black. Early stages show up daily (sometimes twice a day); later stages stretch to weeks, months, and finally yearly “lifetime cards.” Because the schedule is fixed and visible, you always know where a card is and when it will come back.
MemBox isn’t designed to warehouse 50,000 random facts. It’s tuned for hundreds or low thousands of precious cards—scriptures, poems, quotes, key definitions, names—where seeing a card many times early on is a feature, not a bug.
Cards travel the same color‑coded review path from Red to Black as you actively recall them over time—it’s the effort of remembering, not just rereading, that counts.
This cadence is intentionally generous early on to reduce failure later. It takes longer to reach the final stages, but the payoff is steadier recall years down the road.
MemBox isn’t built for last‑minute exam pushes or ultra‑dense mega‑decks. The schedule is intentionally generous: you’ll see important cards a lot in the early stages so the wording becomes automatic, then far less often as they move into long‑term “lifetime” stages.
MemBox is not a clone of SM‑2, SuperMemo, Anki, or FSRS. There’s no mode chooser, ease factors, or tuning sliders—just one clear schedule. In exchange for that simplicity, MemBox deliberately accepts a few extra reviews so you get deeper, word‑perfect recall over years instead of shaving off every “unnecessary” repetition.
Simple levels. MemBox is a modern, color‑coded Leitner‑style path with fixed cadences and an optional Difficult bucket for extra practice.
Adaptive ease + intervals; great for huge decks. MemBox trades some efficiency for clarity and lifetime predictability.
Models stability via history; powerful but complex. MemBox keeps one understandable schedule you can trust without tuning.
If your goal is 50k+ facts with maximum efficiency, a traditional adaptive SRS may fit better. If your goal is carrying a smaller set of texts word‑for‑word for life, MemBox is built for that.
From a plastic card box with a stamped 8‑stage schedule to an iOS app I could finally keep up with.
I grew up thinking I was dumb. A missionary handed me an eight‑stage review pattern that changed everything. I rebuilt my deck, filled a literal Memory Box, and proved to myself that the problem wasn’t intelligence—it was process. Years later I turned that pattern into MemBox so I could carry it in my pocket.

Test
Use Test sessions to quiz yourself either as pure practice or to update the review schedule.
Review
Custom 8‑stage schedule (Red → Orange → Blue → Yellow → Purple → Green → Brown → Black) moves cards from short‑term to long‑term memory.
MemBox is built for verbatim memory and lifetime retention of a smaller, precious set of cards—not last-minute exams or 50,000 shallow facts.
Most systems quietly top out after a few years. MemBox bakes in Brown (2×/year for 2 years) and Black (1×/year for life), so your most important cards never age out of the system.
Generic SRS engines chase efficiency and push intervals far apart as soon as something feels easy. MemBox keeps early stages intentionally dense (Red + Orange) so wording becomes automatic, not just vaguely familiar.
Other apps constantly tweak intervals in ways you can’t see. MemBox uses a fixed, color-coded path you can actually understand, so you always know what each stage means and when cards will come back.
MemBox assumes you’re guarding hundreds or low thousands of high-value cards—scriptures, prayers, speeches, protocols. It happily “wastes” a few extra reviews in exchange for near word-perfect recall years later.
The color stages also tell a story: getting a verse to Green, Brown, or Black feels like a milestone. That narrative keeps you coming back in a way a raw interval number never could.
Do rapid passes over new cards with timers, shuffles, and simple controls that keep you moving instead of tinkering.
Break long passages into smaller prompts or cloze-style blanks so you can memorize big pieces one bite at a time.
Start from scratch or bring in cards from CSV, and export your decks when you want a backup or a printable copy.
Optional encrypted backups keep your decks safe in iCloud so you don’t have to think about manual saves.
See streaks, stage distribution, and gentle trends—no spreadsheets or overload, just enough to stay motivated.
Create cards, memorize them, test yourself, then follow the color‑coded schedule—no mode chooser or tuning needed.
Retain verses, vocabulary, phrases—verbatim.
Deliver quotes and key passages from memory.
Keep terms, numbers, and procedures at your fingertips.
Names, dates, places, poems—what matters most.
Never miss the dates that matter.
Keep critical numbers on instant recall.
Keep technical relationships and key numbers on instant recall.
Details for work and home.

Most spaced-repetition apps use complex adaptive algorithms to manage very large decks. They constantly tweak intervals behind the scenes and aim for maximum efficiency.
MemBox takes a simpler, more focused approach:
If you want to memorize thousands of trivia-style facts, a traditional SRS tool might be a better fit. If you want to carry scripture, quotes, and other important texts word-for-word for decades, MemBox is made for that.
