Every property type
A simple guide to every kind of property you can add to a Collection — what it holds, what it looks like, and when to use it.
A property is one piece of information on an entry. A book has an Author, a Rating and a Cover. A workout has its Exercises. A task has a Due date and a Done box.
Each property has a type. The type decides what you can put in it and how it looks. Pick the type that matches how you want to read the data later — a number you want to chart is a Number, not Text.
All types at a glance
Click a card to jump to it. The groups match the Add a property menu in the app.

How to add a property
- Open an entry, or open the Collection and go to its Properties tab.
- Click + Add a property.
- Pick a type. Search if the list is long.
- It shows up right away, with its settings open. Give it a name.
Basic
Text
A short line of words. Use it for names, places, authors and quick notes.
Good for: the author of a book, the restaurant you ate at, a one-line comment.
Number
A number, with decimals if you need them. You can give it a unit, like kg, km or kcal. Numbers are the type you can add up, average and chart on your Dashboard.
Good for: reps, weight, calories, pages read, a 1–10 rating.
Checkbox
A tick box. It is either done or not done. One click ticks it.
Good for: habits (Did I drink 2 L of water?), to-dos, Watch later.
Tags
Coloured labels you pick from a list. Type a new label and click Create to add it to the list for next time. Two switches in the property's settings change how it works. You can flip them at any time and keep your tags:
| Setting | Off | On |
|---|---|---|
| Allow multiple tags | Pick one tag, like a Status | Pick several, like Genres |
| Use global tag pool | The labels belong to this Collection | The labels are shared by all your Collections |
Good for: a task's Status (To do · Doing · Done), a book's Genre, a habit's Category. Tags are also the usual way to split a Board view into columns. More in Tag and Multi-tag.
Page
A full page to write in, like a Notion page. It has headings, lists, to-do boxes, quotes, images, videos and links to other entries. Type / to see every block.
Good for: a journal entry, meeting notes, a recipe's method. See Pages & nesting.
Picture
One or more pictures. Upload a photo, or paste a link to an image. Pictures show on the entry's card, and they become the covers in the Gallery, Mosaic and Books views.
Good for: a meal photo, a book cover, a progress picture, a screenshot of an article.
URL
A web link. Click it to open the page.
Good for: the article you saved, a video, a product page.
Color
A colour swatch. Pick a preset colour or type your own. Use it to colour-code things at a glance.
Good for: giving each Area of your life its own colour.
JSON
Structured data, for power users. Apps and imports use it to keep the full detail of a record, like every sleep stage in a night. You see a short summary, and View data shows everything. It is read-only unless you turn on editing. A Chart property can draw from it. See JSON and Chart properties.
Time
Date & time
A date. The date picker can grow it into more:
- Include time turns a day into a moment, like Tue 14:30.
- Include end date turns it into a range, like 12 → 15 July.
- In the property's settings, set Calendar role to Show on calendar to put your entries on the Calendar on this date.
Good for: a due date, a birthday, a trip, the days you read a book.
Stopwatch
A live timer. Press Start when you begin, and Finish (✓) when you are done. You can Pause and Resume in between. The time is saved as a duration you can add up later.
Good for: deep-work blocks, reading time, chores. Already know how long it took? Use a Number instead. You can also fix the times of a session later. See Stopwatch and Timer.
Timer
A countdown with a goal, like 25 minutes. It works like a Stopwatch but shows the time left. When it reaches zero it does not stop. It keeps counting into overtime, so you never lose the extra minutes.
Good for: a focus session, meditation, a breathing exercise.
Entry information
These are built in. Every entry already has them — you only add them to show them. Removing one from the list never deletes anything.
| Property | What it shows |
|---|---|
| Entry date | The date and time the entry belongs to. It places the entry in your log and on the calendar. You can change it. |
| Created at | When the entry was made. Read-only. |
| Updated at | When the entry last changed. Read-only. |
| Related Entries | Every entry this one links to, or that links to it. |
| Files | Every file this entry uses — in its page, its pictures and its banner. |
Relationships
Relation
A link to other entries. A task can point to its Area. A reading session can point to its Book. Click the + to pick an entry. Click the × on a link to remove it — an Undo button shows up if you change your mind.
In the settings you choose One entry or Many entries, and the Allowed collections it can point to. It can point to its own Collection too. The other Collection gets no new field on its own. Add Related Entries there to see every link in one place. See Relations.
Good for: Task → Area, Reading session → Book, Meal → Recipe.
Calculations & controls
Formula
A value that works itself out from other properties, like a spreadsheet cell. You write a short rule once, and every entry gets its own answer. It is read-only — change the inputs and it updates.
Good for: a Day score that averages Mood and Energy, BMI from height and weight, days left until a due date. See Formulas.
Chart
A small chart inside the entry. It can draw another property of the entry, a few numbers side by side, its sub-entries, or the Collection's history. It is read-only. See JSON and Chart properties.
Good for: the heart-rate curve of a night, the macros of one meal.
Sub-entries
Entries inside an entry. Each one is a full entry of its own Collection, so it still counts in its own charts and streaks.
Good for: the exercises and sets in a workout, the ingredients of a dish, the steps of a morning routine. Give it default sub-entries and every new entry starts with them. See Sub-entries.
Scale values
One dial that scales several numbers at once. Set it to 1.5 and every number it controls goes up by half.
Good for: food. Log 1.5 portions of a meal and the calories, protein, carbs and fat all follow. See Sub-entry formulas and Scale values.
Special tracking
Heart rate
A heart-rate line for a stretch of time — a day, a workout or a night's sleep. It fills in when you connect a wearable, or you can paste your own readings. See Pasting Heart rate.
GPS distance
A recorded route. Add it to any Collection and each entry gets a Start button. Tap it in the Android app to record your run or walk with GPS. The property shows a map of the route. The distance, pace and other numbers go into your own properties, like Distance and Pace. Runs from a connected watch arrive in the same shape. See Recording runs.
Other types you may see
A few types are not in the Add a property menu, but you may find them on your entries:
- Screen time breakdown and Source log are filled in by connected sources, like the browser extension or the desktop app. See Automatic screen time.
- Email and Phone hold an email address or a phone number as text. Turn a Text property into one with Change type….
- Select, Multi-select, File and Rollup are older types. Old ones keep working, but you cannot add new ones. Use Tags, Picture and Formula instead.
