What is a Collection

A Collection is the shape of one kind of thing you track — defined once, reused forever.

A Collection in Kaizendex is the shape of something you want to track. Push-ups, sleep, coffee, a book finished, a mood reading — each one is its own Collection. You define a Collection once, and from then on every time you log that activity it slots into the same shape.

Think of a Collection like a form with the Properties you care about, that you fill in over and over — each time you log an Entry of that Collection you write one value per Property.

Examples of Collections

There's no limit. Some popular categories and what their Collections might look like:

Workouts

  • Push-ups — reps (number), set (number)
  • Run — distance (km), duration (minutes), pace
  • Bench press — weight (kg), reps (number), set (number)
  • Yoga session — duration (minutes), style (text)

Health & body

  • Sleep — hours, quality (1–5), wake-up mood
  • Weight — kg (or lbs)
  • Water — glasses
  • Meds taken — taken (yes/no)
  • Blood pressure — systolic, diastolic

Food

  • Coffee — cups
  • Protein — grams
  • Meal — name (text), calories, protein, carbs, fat
  • Alcohol — units

Habits & mood

  • Habits — Category (tag), done (yes/no) — one Collection holding all your simple habits (see below)
  • Meditation — session (live timer with a target)
  • Mood — rating (1–5), note (text)
  • Gratitude — note (text)
  • Pomodoro — focus (Timer, target 25 min)

Reading & learning

  • Pages read — pages, book (link to Book Collection)
  • Book finished — title, author, rating, notes
  • Flashcards — reviewed (count), accuracy (%)

Work

  • Deep work session — duration (live stopwatch — Start when you sit down, Stop when you're done), project, note
  • Meeting — name, duration, was productive (yes/no)
  • Gardening — time (live stopwatch). Phone in pocket, Start when you go out, Stop when you come back.

You can mix any of these in a single account. They all live in the same feed.

One Collection per shape, not per thing

Notice that Habits is a single Collection above, not one per habit. That's the rule worth learning early:

Make a new Collection when the thing needs different fields. When it only needs different starting values, make a preset inside a Collection you already have.

Brush teeth, Candy free day and Read today are all "a title and a tick" — same shape, so one Habits Collection with three presets. A Run needs distance, a route and a pace, so it earns its own Collection. Twenty habits should never mean twenty Collections: your sidebar, your pickers and your AI all have to carry every one of them forever.

See Tracking habits for the pattern end to end.

Why Collections are useful

Because every Entry slots into a Collection, you get a lot for free:

  • Consistency. Every push-ups Entry has the same Properties, so trends and averages just work.
  • Speed. With a default value on the main Property, logging is one tap.
  • Aggregation. A Rollup runs server-side per numeric Property — your Dashboard reads totals and counts straight off it.
  • Editing. Need to add a notes Property to Push-ups two months in? Add it. New entries get it, old entries still work.

Tagging your Collections

You can label a Collection with your own tags — small colored chips that sit right under its title. Add as many as you like: "Health", "Work", "Fun" — whatever helps you organize your own set of Collections. Tap + Add tag to search your existing tags or type a new name to create one on the spot; click any chip to rename it, recolor it, or remove it.

If a Collection is receiving data automatically — say, sleep synced from a wearable, or screen time from the desktop tracker — it also carries one outlined Auto-synced chip. That one you don't control directly: it appears the moment a sync stream starts writing to that Collection and disappears the moment it stops (see Connecting a wearable). Tags are purely labels — adding or removing one never changes what data goes where.

Two ways to create a Collection

  1. Implicit (from chat). Type a brand-new name in the search bar at /chat. Pick Create new collection called "X". Kaizendex picks a sensible default shape (usually one numeric Property), and you can refine it later. This is the fast path.
  2. Explicit (from /collections). Go to /collections/new to design the full shape up front — name, emoji, color, Properties, Title, defaults. This is the right path when you know exactly what you want.
