How Mocavoca’s 1–3–7–14–30 Spaced Repetition Works
On Monday morning on the train, we drill a new word five times in a row, get it right every single time, and close the app feeling certain we own it. Then on Thursday afternoon, that exact word shows up in the second paragraph of a reading passage—and our mind goes completely blank.
The reason a word can feel rock-solid on Monday and vanish by Thursday comes down to how short-term memory works. Drilling the same word five times in ten minutes only refreshes working memory—the same mental scratchpad we use to hold a pickup number on a coffee receipt for thirty seconds before throwing the slip away. And when a flashcard app catches a mistake and immediately shows us the exact same question two seconds later, tapping the right answer relies on visual echo rather than real recall.
Turning short-term impressions into long-term memory
For a word to stay accessible months later in an exam room or journal paper, each review needs space and sleep in between. When we designed Mocavoca’s 1 → 3 → 7 → 14 → 30 day spaced repetition ladder, we built in three safeguards that close off short-term shortcuts.
At the heart of the schedule is a strict calendar boundary: every promotion on the ladder requires at least one full calendar day and a night’s sleep. Even if we practice the same word three times on Monday afternoon and answer it flawlessly each time, its review level will not jump two steps in a single day. Even if we finish learning a word at 11:55 PM and open a review session ten minutes after midnight at 12:05 AM, Mocavoca logs the practice without letting the word skip ahead on a midnight technicality. Only after a real calendar day (≥24 hours) has passed—and we answer independently without opening a hint—does the word climb along the 1, 3, 7, 14, and 30 day steps.
During each 4-word group, every card is checked three ways: meaning selection (meaning), blind audio recognition without text on screen (listening), and full keyboard typing (spelling). Whenever we slip on one of those checks—or tap the letter-hint button—Mocavoca never hands us an instant retry on the very next screen. Instead, it tucks the card away and inserts at least 2 other words in between. Once the visual echo fades, the missed word comes back for a genuine retry, and its long-term review interval resets to tomorrow (+1 day).
On the other hand, we never have to waste daily energy on words we already know well. When a familiar foundation word appears on a card, tapping “Mark as familiar” skips today’s three-step drill and schedules a single verification check 3 days later, saving our daily 15 minutes for genuine new vocabulary.
| Scenario | Ladder step | Requirement | Next review |
|---|---|---|---|
| New word | Stage 0 → 1 | Pass meaning, blind audio & spelling | In 1 day (+2 coins) |
| Already knew it | Direct to Stage 1 | Tap “Already knew it” on card | In 3 days |
| Cross-day review | 1 → 3 → 7 → 14 → 30 days | ≥24h elapsed, 0 hints used | Next step (Mastered at 30d) |
| Same-day repeat | Unchanged | Practiced again on the same day | No jump, 0 extra coins |
| Missed or hint used | Reset to Stage 0 | Any error or letter hint opened | Retry after ≥2 words, then 1 day |
Keeping daily sessions around fifteen minutes
Because every new word we learn today returns on Days 1, 3, 7, 14, and 30, our daily review queue naturally builds over the first ten days until the combined total of due reviews and new words settles at roughly three times our daily new-word setting.
Setting our daily pace to 8 or 12 new words per day keeps that Week-2 convergence around two to three dozen words in total—an easy 12 to 15 minutes over morning coffee or on the commute. Each time we open the café, clearing due reviews first before starting new cards keeps the 1–3–7–14–30 day rhythm steady. And if exams or travel pull us away for several days, Mocavoca’s daily review cap serves a manageable 15-minute slice rather than dumping hundreds of overdue cards on screen at once.

Frequently asked questions
Why doesn’t Mocavoca let me promote a word’s 1–3–7–14–30 day level twice in the same day?
Answering a word five times in one afternoon mainly tests short-term working memory. Requiring a real 24-hour calendar boundary ensures you have slept on the word and can retrieve it from long-term memory the next day.
What should I do if my daily review queue feels heavy in Week 2?
Open Settings and temporarily lower your daily new-word goal to 5 new words per day for three or four days. That lets you clear the wave of Day-3 and Day-7 reviews in under 10 minutes before turning your pace back up to 8 or 12.
