-- BEHAVIORAL PRODUCTIVITY — NOT ENGAGEMENT THEATRE
3-task cap. Midnight wipe. Free during early access.
Two questions everyone asks
"But I have more than 3 things to do."
You do. JUST. is not for all of it.
"Why not just use a notebook?"
You can. Four things a notebook cannot do.
The obsession formula
"JUST. Like that."
Unfinished tasks vanish at midnight. Not archived. Gone. Guilt is not a productivity strategy. A clean slate is.
Loss Aversion · KahnemanSome research suggests self-control draws on a limited resource. When it's depleted, starting anything new gets harder. Three tasks means you spend that resource on what matters.
Ego Depletion · BaumeisterEvery day you finish 2 out of 3 tasks your streak grows. Miss a day and it resets. The fear of losing a streak is more powerful than the desire to build one. That is loss aversion. That is why it works.
Loss Aversion · KahnemanNotifications can disrupt focus mid-task. One optional morning nudge. That is the entire notification system. Respect for attention is not a feature. It is the position.
Attention EconomicsInspired by research on embodied cognition — the idea that physical sensation shapes how we think. Cream paper. Monospace ink. Hand-drawn checkboxes. Tactile satisfaction is not vanity. It is the reason you come back.
Embodied CognitionThe science of focus
Every feature is a lever for your behavior.
Zeigarnik Effect
40%
Unfinished tasks create lingering cognitive tension and intrusive thoughts, making it harder to focus on what's in front of you.
Hick's Law
3x
Decision time increases non-linearly with the number of choices. Three tasks is not arbitrary — it's the point where the list stops fighting you.
Implementation Intentions
2x
People are roughly twice as likely to complete a task when they state when and where they'll do it. JUST. prompts this every morning.
Why everything else fails
"They grow when you procrastinate.
JUST grows when you don't."
Them
"Add everything. Tag it. Categorize it. Archive it."
Us
"If it's not one of your top 3, it doesn't exist today."
Them
"Streaks based on opening the app."
Us
"Streaks based on finishing what you started."
Them
"Infinite scroll of yesterday's failures."
Us
"Midnight wipe. Every day is Day 1."

Founder
Productivity culture sold us a lie. More tools. More systems. More integrations. As if the problem was organisation, never discipline. It wasn't. The problem was infinite optionality dressed up as productivity.
JUST exists because constraint is a decision. Three tasks. Midnight wipe. No backlog. Not for aesthetics, but because the brain performs better when the choice is already made. Fewer decisions. More execution.
JUST began as a personal protocol. A way to end the cycle of planning over finishing. The structure worked. The negotiation stopped. This isn't a productivity app. It's a daily commitment mechanism, designed to close the gap between intention and action. Built for people who are done negotiating with themselves.
