Apps for ADHD High School Students: A Free-First, School-Device Stack
A homework, calendar, timer and reading stack that runs on a board-managed Chromebook for free, one paid upgrade worth it, and a 30-minute setup.
The school hands out a locked-down Chromebook. The phone has to stay in the bag during class. The family budget does not stretch to another subscription, and even if it did, the last three apps were abandoned by Thanksgiving.
That is the real environment for apps for ADHD high school students in Canada, and it rules out most of what gets recommended online. What is left is a small stack of free tools that run inside the Google or Microsoft account the board already gave your teen, plus one paid upgrade that is worth it in a specific situation.
Here is the stack, in the order to set it up, and a thirty-minute session to set it up together without an argument.
Why free-first: subscriptions die when the term gets busy
A paid app has to earn its place every month, and the month it stops earning it is usually week eight, when the term gets hard and the teen stops opening anything. The subscription keeps billing; the habit is gone. Free tools do not have that failure mode. They sit in the account, cost nothing while ignored, and are still there on the Sunday when the teen is ready to try again.
Free-first also matches how school devices work. Most board-managed Chromebooks block app installs but allow the full Google Workspace, and most board Microsoft accounts include the web versions of Word and OneNote. Build on what is unblocked.
Calendar and homework tracking that works on a school-managed device
- Google Classroom or Brightspace as the source of deadlines. Whatever the board runs, the To-do or Assignments view already lists every due date. The habit is checking it at a fixed time, not re-entering it somewhere else.
- Google Calendar for anything the LMS does not know. Tests announced in class, the band trip, the dentist, the shift at the grocery store. Teens enter these themselves, with two alerts, from the Chromebook or the phone. If the board account blocks the phone app, use a personal Google account and share the calendar into it.
- Google Tasks for the small stuff. 'Bring gym clothes', 'return the library book', 'ask Ms. K about the retest'. It sits in the Calendar sidebar, so it is seen without opening another app.
- Google Keep for the brain dump. One pinned note titled Today, rewritten each morning with three items. It is the paper list for people who lose paper.
The daily routine is two minutes: open Classroom's To-do, open Calendar's week, rewrite the Keep note. Our answer on which digital ADHD tools help high school students with time, reminders and focus explains how to make the reminders in this stack hard to ignore.
Timers and focus tools allowed in class
With phones restricted in classrooms across several provinces, the timer has to live somewhere else.
- A browser-tab timer on the Chromebook. Any visual countdown site or a simple timer extension works during independent work, and most boards allow them. A visible shrinking bar on the corner of the screen does more for many teens with ADHD than a number in the clock.
- A physical visual timer. A dial timer with a coloured disc that shrinks as time passes costs roughly 40 to 60 CAD and is allowed everywhere, including exams in some schools when written into the IEP. It is the one piece of hardware on this list worth buying.
- A focus playlist with no lyrics, if the teacher allows headphones during work periods. Free on any streaming service; brown noise is a good default.
- Filtered earplugs for noisy rooms, which cut chatter without blocking the teacher and raise no eyebrows. Our post on dealing with distractions in class covers the non-tech side of this.
Reading and writing supports
All of these are already inside the accounts most boards provide, which means no permission slip and no cost.
- Read aloud. Chrome's built-in reading mode, the Read Aloud extension, or Immersive Reader in Microsoft Edge and Word turn any assigned reading into audio with the text highlighted as it goes. Two channels for attention instead of one.
- Voice typing. Google Docs has it under Tools. A teen who freezes at a blank page can talk a messy paragraph, then fix it. The first draft exists, which was the hard part.
- The outline pane. Google Docs shows headings in a side panel. Typing the headings for an essay before writing anything turns a blank page into a form to fill in.
- A grammar checker, free tier only, run once at the end. Many boards license one; ask the teacher.
One paid upgrade worth considering, and when
If the free stack has held for a month, meaning the teen is checking Classroom and Calendar most days, and the remaining problem is the after-school hours dissolving with nothing started, a timeline planner app on the phone can be worth the money. Structured and Tiimo draw the afternoon as a strip of blocks, count down to the next one, and nag at the transitions, which is where many teens with ADHD lose the evening. Structured is around 4 CAD a month or a one-time fee; Tiimo is about 80 CAD a year.
The condition matters. Buying the planner app before the free stack holds just adds a fourth place to not look. And if the teen's problem is forgetting deadlines rather than losing afternoons, the upgrade will not touch it.
A parent-teen setup session that takes 30 minutes
Pick a low-stakes evening, not the night before a test. The teen holds the device. The parent holds the list.
- Minutes 0 to 5: the teen names the one thing that cost them most marks last term. That is the only problem tonight.
- Minutes 5 to 15: set up the piece of the stack that addresses it. Deadlines missed means Classroom plus Calendar with two alerts each. Work not started means the Keep note plus a timer. The teen types, chooses the alert times, picks the sounds.
- Minutes 15 to 20: the teen explains the setup back to the parent. If they cannot, it is too complicated. Simplify until they can.
- Minutes 20 to 25: agree the one daily question the parent is allowed to ask for two weeks, such as 'did the Classroom check happen?'. Nothing else about the phone.
- Minutes 25 to 30: put a 15-minute review on both calendars for two weeks from now. That review decides whether to keep it, change it, or add the next piece.
If the stack keeps collapsing no matter who sets it up, that is information rather than failure. Our answer on supporting a teen with ADHD at school covers what to raise with the school, and our guide to navigating high school with ADHD is written for the teen rather than the parent, which is sometimes the version that gets read.
