ScentMemory - Scent and Memory Diary
A whiff of sunscreen, a neighbour's cooking, rain on a hot pavement - smells can pull up a memory you had not thought about in years, often with the feeling attached. ScentMemory is a small diary for exactly those moments. You write down the scent, the memory or emotion it brought back, how strong it was and, if you like, where you were.
Over time the entries become a personal map of the smells that matter to you. You can scroll back through them, search for a word, filter by category and look at simple charts of what you notice most. It suits fragrance hobbyists, people keeping a mindfulness or gratitude journal, writers collecting sensory detail, or anyone curious about why a certain smell always makes them feel at home.

How to use ScentMemory
- Start a new entry. On the Home tab, tap the round + button at the bottom right to open the New Record screen.
- Describe the scent. In the first box write what you smelled, for example "wet cut grass" or "cinnamon rolls in an oven". Be as specific as you can.
- Write the memory. In the second box note the memory, person, place or feeling the smell brought back. Both the scent and the memory are required before you can save.
- Pick a category and intensity. Choose a category such as Food, Nature, Artificial Scents or Places, then move the slider from 1 (weak) to 5 (strong). Optionally type the location where you noticed it, then tap Save.
- Browse, search and edit. Home lists your entries newest first, labelled Today, Yesterday or a number of days ago. Use the search box or the category chips to narrow the list. Tap an entry to edit it, or use the delete icon in the edit screen to remove it.
- Manage categories. Tap the category icon in the top bar of the Home tab to add your own categories, such as Perfume or Childhood. Custom categories can be deleted; the built-in ones cannot.
- Look at your statistics. Open the Statistics tab to see your total entries, entries made today, average intensity, a pie chart of categories, a bar chart of intensities, a weekly trend line and your recent memories.

Why smells bring back memories, and how to write them down
The Proust effect
In Marcel Proust's novel In Search of Lost Time, the narrator dips a madeleine cake into tea and, from the taste and smell, a whole stretch of his childhood comes back to him. The idea that a scent can suddenly unlock a vivid, emotional memory is now often called the Proust effect.
Many people recognise it from daily life. Smell is wired a little differently from our other senses: signals from the nose reach brain areas involved in emotion and memory very directly, rather than passing through the same relay station as sight and hearing. That is one commonly given reason why smell-triggered memories tend to feel emotional and come from early in life, even when we cannot name the smell itself.
Describing a scent in words
Most of us lack a ready vocabulary for smells, so we fall back on the source: it smells like oranges, like a hospital, like grandma's house. That is perfectly fine for a diary. The source is often the most useful description, because it is what you will search for later.
If you want to be more precise, try a few angles. Name the family: citrus, floral, woody, smoky, green, spicy, sweet, earthy, fresh or musty. Add texture: sharp, powdery, creamy, metallic, dusty. Note how it changed: perfumes and cooking smells often shift from a bright opening to a deeper base after a few minutes. And note the context, because the same smell can read very differently in a kitchen and in a car.
What to write in the memory field
The memory does not have to be a full story. A name, a year, a room or a single feeling is enough to anchor it. Useful prompts are: Where was I the first time I smelled this? Who was there? What season was it? How did my body feel - calm, nervous, hungry, safe?
Sometimes a smell brings back a mood but no clear event. Write that down too. Those vague entries are often the ones that become clearer when you meet the same scent again and add a second note.
Using intensity and categories well
Intensity works best if you decide what it means to you and stay consistent. One option is to rate how strong the smell physically was. Another is to rate how strongly it hit you emotionally. Mixing the two makes the average less meaningful, so pick one.
Keep categories few and broad at first. Five to eight is plenty. If you find yourself constantly typing the same word into the scent box, such as a particular perfume house or a type of tea, that is a good sign it deserves its own category.
Making it a habit
Scent moments are fleeting, so write them down soon after they happen, while the details are fresh. A short entry made immediately beats a long one written days later. Reviewing the list once a week, or looking at which categories dominate the charts, can show you which places and people your nose connects you to most.
Frequently asked questions
Where are my entries stored?
Only in this browser on this device, using its local storage. There is no account and nothing is uploaded to a server. If you clear your browser's site data, use a private window, or switch to another browser or device, your entries will not be there.
Can I move my entries to another device?
Not in the web version. There is no export or sync, so entries stay in the browser where you created them.
How is the web version different from the phone app?
The core diary, search, categories and statistics are the same. The iPhone and Android apps keep entries on the phone itself and offer an optional upgrade to remove ads; that upgrade is not available on the web.
Do I need to fill in the location?
No. Location is optional and is plain text you type yourself. The app does not read your GPS position.
Why can't I delete some categories?
The built-in categories (Food, Nature, Artificial Scents, Places and Intensity) are protected. You can add and delete your own categories freely.
Can I use it in another language?
Yes. It follows your browser's language when available. You can also add ?lang= and a language code, such as ?lang=ja for Japanese or ?lang=fr for French, to the page address.
Limitations of the web version
- Entries are saved only in this browser; clearing site data deletes them
