## What is SPARC Load?

Not all days weigh the same.

SPARC Load measures what a day costs you: not how many things are on it, but what each one actually takes.

Two numbers, two questions
The score, from 0 to 100, says how intense the day is. The hours beside it say how much day is left. A morning with one heavy meeting and a day filled with small errands can score the same and feel nothing alike, because the score is an average and the hours are a sum. Added up, the hours are told against sixteen: the day you are awake for, twenty four minus sleep.

Eight axes
Describe a commitment across Mental Energy, Physical Energy, Importance, Deadline, Friction, Dependency, Span and Drain. Four of them carry a percentage weight and make the base. Friction and Dependency correct it, up or down. Span and Drain multiply what the others decided. A fixed start time adds ten percent, because knowing something is coming has its own cost.

Three bands
From 0 to 40, a light day: room to think, to be flexible, to say yes to surprises.
From 41 to 70, an intense day: it asks for focus and a real evening to recover in.
From 71 to 100, a full day: maximum concentration, minimum margin. A day like this needs a light one after it.

The price before you pay it
When you add a commitment, the sheet says what it costs: plus two hours, and the day it leaves you with. Past twelve hours it says the rest out loud. SPARC Load does not stop you and does not tell you what to choose. It tells you the price first.

Predicted against lived
In the evening the app asks how the day went: lighter, as expected, or heavier than the score. It is not a correction. After seven check ins, Stats shows whether you systematically overestimate or underestimate your load. Knowing which way you lean is the whole point.

Not a calendar
SPARC Load does not tell you what to do or when. You can log commitments after the fact: forgot a morning call, add it in the evening. The only rule is the honesty of the estimate.

Everywhere your day is
iPhone and iPad, with a two column layout on iPad and a radar for every commitment. Apple Watch, with the day averaged into one shape and three complication styles. Home Screen and Lock Screen widgets. A Live Activity that follows the heaviest commitment of the day. And on Mac, with the load in the menu bar.

Where the name comes from
SPARC is an acronym, and each of its five letters is a way of looking at a problem: simplicity, pragmatism, abstraction, reasoning, context. The eight axes are not those five words, they are what the words become when the problem is a day instead of a project. The method is told in full in Framework SPARC, a book by Luca Infante that is written in Italian.

Free, with no ads, no subscription and no tracking. If it earns its place, there is a one time tip inside.

## Version history (last 3 releases)

### 2.2.0 — 2026-09-23

SPARC Load now speaks Portuguese, European and Brazilian, alongside English, Italian and Spanish.

The Why? tab has a new section on where the name comes from: what the acronym stands for, and why the eight axes are not the five words of the method but what those words become when the problem is a day instead of a project.

The score colours now clear the required contrast on cards as well, where they had only been measured against the background, and the three axis dots tell themselves apart by shape and not only by colour. The layout holds at the largest text sizes iOS offers.

### 2.0.0 — 2026-08-18

Your day now has two numbers instead of one.

Hours beside the score
The score says how intense a day is. It could not say how much of it there is. Now every commitment carries its length, and the day adds them up against sixteen hours: twenty four minus sleep, the one subtraction that holds for everyone. When you add something, you see what it costs before you commit to it: plus two hours, and the day it leaves you with.

SPARC Load on Mac
A native Mac app, with the day in the menu bar and the same model behind it.

A weekly look on Sunday
One invitation, in the evening, to look at the week before it starts. The time is yours to choose in Settings.

Also in this version: the Guide now shows exactly how the score is built, the Stats chart says how many days it actually has, and the check in no longer flashes to zero when you cancel it.

### 1.0.0 — 2026-05-04

No release notes.
