ADHD planner app: built for brains that need a reward now

Daniel Gavalec · Updated October 13, 2026

An ADHD planner app is a planner designed around common ADHD-style struggles – losing thoughts before they are written down, misjudging how long things take, freezing in front of big tasks and running out of motivation halfway. CORTEX is a free daily planner app that tackles these with quick capture, a one-click day plan, small subtasks and instant XP rewards. It is a productivity tool, not a medical device or a treatment.

What an ADHD-friendly planner needs to do

ADHD (attention-deficit/hyperactivity disorder) involves ongoing patterns of inattention and/or hyperactivity-impulsivity, according to the US National Institute of Mental Health. Everyone's experience is different, and a planner is no substitute for professional support. But many adults with ADHD – and plenty of people without a diagnosis – describe the same day-to-day friction with classic planners:

Quick capture: get it out of your head in 5 seconds

If saving a thought takes six taps and a form, it doesn't get saved. In CORTEX you press Q (or tap the floating button on mobile) and type like you would text a friend:

Call dentist tomorrow @9 ~10m !p1
Pay electricity bill friday !!
Buy birthday gift for Mia ~30m #Family

CORTEX reads the date (tomorrow, friday, 24.12.), time (@9), duration (~10m), priority (!p1, !!) and goal (#Family). Anything without a goal lands in the Inbox, so you can sort it later when you have the energy. Capture now, decide later – the core idea of Getting Things Done.

Plan My Day vs. time blindness

"Time blindness" is a popular way to describe how time can feel either like now or not now, with nothing in between. A to-do list makes this worse: twelve tasks, no times, and somehow it is 4 pm.

Plan My Day turns the list into a timeline with one click:

1. It takes today's tasks, overdue tasks and undated tasks.
2. It keeps your fixed-time appointments where they are.
3. It fills the free gaps of a 09:00–22:00 day, starting from now, in 15-minute steps.
4. Order: overdue first, then by priority, then shortest first (quick wins).
5. It tells you honestly what doesn't fit today – that list is your permission to stop.
6. "Apply" writes the times into your tasks; "Re-plan" recalculates when the day blows up.

It is rule-based, not AI, so you can predict what it will do. No mystery, no "why did it put that there?". Working hours are fixed at 09:00–22:00 for now. More on the method in time blocking.

Small subtasks and a timer you can see

"Write report" is a wall. "Open the doc", "write three bullet points", "add the numbers" are steps. In the CORTEX planner, each task can have subtasks with a progress bar, so you see movement even when the big task is far from done.

Two more features help with starting and staying on task:

• Focus timer in the top bar: 15, 25 or 50 minutes with a visible progress bar, an in-app "done" notification and optional ambient sounds (Lofi, Synth, nature, Zen, alpha waves). Fifteen minutes is a great "just start" setting. See the free Pomodoro timer.
• Work timers on the Today screen: named Start/Stop timers that log real minutes to your reports, so you learn how long things actually take. That feedback is gold if your estimates are always off.

Instant rewards: XP now, not in six months

Long-term goals pay out in months. Many ADHD-style brains want feedback in seconds. CORTEX adds a game layer that closes the loop immediately:

• XP for every finished task, more for higher priority and longer estimates. Levels and ranks show long-term progress.
• Credits you spend in a reward shop stocked with your rewards: an episode, a snack, a gaming session.
• A daily reward of 100 credits for showing up, and achievements along the way.
• Attributes – quick tasks of 15 minutes or less give a DEX bonus, so tiny tasks count.

The design rule: rewards follow finished work, not time spent fiddling with the app. Read more in the RPG habit tracker.

A simple ADHD daily routine in CORTEX

1. Morning (3 min): open Today, read the morning brief and set the "Prime directive" – the one thing that makes today a win.
2. Plan (1 click): press Plan My Day, check what doesn't fit, hit Apply.
3. Start small: 15-minute focus timer on the first task. Only goal: start.
4. During the day: anything that pops into your head goes into quick capture, not into the current task.
5. Day blew up? Re-plan. No guilt, it is a button.
6. Evening (2 min): evening debrief and daily log (energy, focus, sleep, exercise) – it earns XP and over time shows patterns between sleep and focus.

Choosing the best ADHD productivity app (free)

There is no single best ADHD app – brains differ. Use this checklist when you test any free app for a week:

• Can you capture a task in under 10 seconds?
• Does it show your day on a clock, not just as a list?
• Does it give you something good right after you finish a task?
• Does it work without a long setup?
• Is it forgiving when you miss a day?
• Is it really free, or does the useful part sit behind a paywall?

If an app with visual timelines, a paper planner or a simple timer works better for you, use that. The best planner is the one you keep opening. CORTEX is a good fit if games motivate you and you want capture, planning, timers and rewards in one place. It runs in the browser and installs as a PWA on iOS and Android (it is not in the App Store or Google Play).

Important: CORTEX is not a medical device. It does not diagnose, treat or manage ADHD or any condition. For assessment or treatment, talk to a qualified healthcare professional.
