Spaced repetition made simple
Why cramming fades, why timing matters, and how practice spread across days can help a memory last.

The timing of practice can matter as much as the total effort you put into it.
Two people learn the same forty names. One repeats the list in a single sitting until it feels solid. The other uses short practice sessions over the next days and weeks. For many kinds of learning, the second plan helps memories last longer. The size of the effect depends on what you learn and when you practise.
That pattern is called spaced repetition.
How spaced repetition works: use a photo card with the person's name hidden. Look at the photo, say the name from memory, then reveal the written name on the card to see whether you were right.
Saying the name from the photograph gives you practice for meeting the person again.
Use the card again the next day. If you can remember the name easily, wait about three days before the next try. Then wait a week and two weeks while the name stays easy. If you forget it, try again later that day or the next day.
These times are examples, not strict rules. Wait longer after an easy answer and come back sooner after a hard or wrong answer.
Why the timing matters
In the 1880s, a German memory researcher named Hermann Ebbinghaus learned lists of made-up sounds. The sounds had no meaning, so old knowledge could not help him. He then checked how much he remembered over time.
His work gave us the basic idea of a forgetting curve. We often forget fastest soon after learning, then the loss slows down. There is no single curve for every person or every subject. Meaning, old knowledge, sleep and later practice can all change it.
For names, two lessons are useful.
Practise early. You may forget fastest just after learning. A same-day try lets you strengthen the name or fix a mistake.
An easy answer can earn a longer wait. If you remember a name after one day, you may wait three days before the next try. As the name gets easier, the waits can grow from days to weeks and then months. Each person and each name may need a different plan.
Why cramming can mislead
Cramming can make you feel sure that you know the names.
Read a team list again and again, and the names soon look familiar. That feels good. It does not show that you can say a name in the corridor three days later.
Practice after a wait often feels harder. Some names come slowly and some are gone. That is normal. The task now looks more like the real moment when you need the name later.
Researchers sometimes call this a desirable difficulty. The practice feels harder now, but it may help the answer last. Easy practice is not always strong practice.
Why saying the answer beats rereading
There are two basic ways to review a name. You can look at the face and written name together. You can also hide the written name, look at the face, say the name from memory and then reveal the correct answer.
The second approach often helps the name last longer. The effort to say the name is part of the learning. Seeing the correct answer right after also matters.
A wrong answer can still lead to learning if you see the correct name right away. The fix matters. A wrong guess on its own does not teach you the right name.
For name practice, keep the written name hidden until you have said your answer. Then reveal the correct name. This is called retrieval practice. You must bring the name to mind instead of only seeing it on a page.
Choosing the next practice date
Try again too soon and the answer may still be fresh. That can feel easy without helping much later. A few close tries can help a new name, but many repeats in one sitting can fool you.
Wait too long and you may forget the name. You then need more time to learn it again. This does not mean that all the old work is gone.
Aim for the space in the middle. Wait long enough that the name takes some effort, but not so long that every card feels new. No fixed set of dates works for every name. The next date should change after each answer.
How easily you remember a name can guide the next practice date. If the name comes to you immediately, wait longer before practising it again. If you hesitate or forget it, practise it sooner.
Doing it by hand
You do not need software. You can use this simple plan:
- Try the name again on the same day, within a few hours if you can.
- Try again the next day or the day after.
- If you can still remember the name easily, wait about a week.
- Keep adding more time between tries by moving to two weeks, a month and then several months while the name stays easy.
- When you forget one, try it again sooner after a day or two. Add more time again once it becomes easy.
- Keep the written name covered until you have said your answer, then uncover it to check.
- Keep easy-to-mix-up people apart by practising two people with the same name at different times.
For a list of ten names, a dated notebook may be all the scheduling you need.
The Leitner box: a physical way to manage the schedule
Spaced repetition is often used for vocabulary. A study card might show a word on the front and its meaning on the back. People have also used cards to learn words for the SAT. The modern SAT does not test long lists of rare words. It asks students to understand useful words and phrases in context. The College Board calls this Words in Context.
For name practice, put a person's photograph on the front of each card and their name on the back.
The Leitner system uses a box divided into sections. Each section represents a different practice schedule. A simple four-section version could work like this:
- Section one: every day. Put every new card here.
- Section two: every three days. Move a card here after you remember the name correctly.
- Section three: every week. Move the card here after another correct answer.
- Section four: every two weeks. Use this section for names that have become easy to remember.
When a section is scheduled, look at the photograph and say the name before turning the card over. Move a correct card one section forward. Move a forgotten or incorrect card back to section one. The sections do the scheduling for you, so "wait longer" becomes a visible place in the box rather than a date you have to remember.
A four-section Leitner box. Cards move forward when the name is remembered and return to the first section after a miss.
What becomes difficult at scale
The task is simple, but the dates get harder to track as the list grows.
With forty names, each person soon has a different interval. Tariq may need another attempt in two days, while Yuna can wait a month and six people added on Tuesday still need short early gaps. A paper system must track which names need practice on each date.
Some people use a paper plan. It can take a lot of work once the list grows. An app can track the dates without changing the task.
Where the app comes in
Namefinity applies spaced repetition to the names and photographs of people you choose to add.
You can add a person from a camera-roll photo, a group shot, a screenshot, your contacts or a manual entry. A short note about where you met provides useful context.
A typical daily practice takes about two minutes. For each person, the app shows the saved photograph while the written name stays hidden. After you say or think of the name, the app reveals it. You then record whether you forgot it, remembered it or found it easy. Difficult names come back sooner. Names you remember easily wait longer.
Five memory boxes show how each name is going: brand new, shaky, getting there, solid and locked in. Before an event, you can practise the names that need the most help.
Sessions stay short because the app shows only the names picked for that day, not your whole list.
Your people, photos and notes stay on your iPhone, with no account, content cloud or ads. The app is free, and you can export a readable copy of your names and notes.
