ClassCallerA reminder app built for the way ADHD brains actually work
The premise: you don't have a discipline problem — you have tools that were designed for neurotypical habits. Every reminder app assumes you'll keep entering tasks and notice silent banners. ClassCaller assumes neither: deadlines sync themselves from Canvas, and reminders arrive as actual phone calls that interrupt whatever the hyperfocus grabbed.
The two places every system dies
1. Maintenance. Todoist, planners, bullet journals — they all work brilliantly for the two weeks you feed them. Then one busy Tuesday you skip the entry ritual, the system silently goes stale, and now it's worse than nothing: it feels handled and isn't. ADHD punishes any tool that needs daily upkeep.
2. Delivery. Time blindness means "due tonight" and "due next week" feel identical until suddenly they don't. A silent banner can't break that spell — it joins the pile of 47 other notifications. Interruption is the only delivery that lands, which is why body doubling, alarms across the room, and a roommate yelling all work when apps don't. A phone call is that interruption, automated.
Zero maintenance
Paste your Canvas calendar link once. Every assignment, quiz, and date change syncs itself. The system survives your worst week, because there's nothing to keep up.
Real interruption
Your phone rings. You answer. A voice says what's due and how long you have. No banner to swipe, no app to remember to open, no willpower required.
Escalation built in
A week out, a day out, an hour out — down to 15 minutes on Pro. Time blindness gets multiple collisions with reality before the deadline hits.
Pick the voice your brain responds to
Novelty keeps reminders from fading into wallpaper — so ClassCaller lets you choose the energy: a chill heads-up, a hype friend, a drill sergeant, or opt-in Unhinged Mode, where an AI writes a different comedic roast for every single call. Plenty of our ADHD users swear the roast is the only reminder format that's ever actually gotten them off the couch. More on why in our ADHD and deadlines deep-dive.
ADHD reminder questions
What's the best reminder app for students with ADHD?
One that doesn't depend on noticing silent notifications or maintaining a manual system. ClassCaller is built on that principle: deadlines sync automatically from Canvas, and reminders arrive as real phone calls — an interruption, not another ignorable banner.
Why don't normal reminder apps work for ADHD brains?
Two failure points: manual entry (the system dies the week you stop updating it) and silent delivery (banners don't break hyperfocus or time blindness). Phone calls fix delivery — a ring demands a response — and automatic Canvas sync removes maintenance entirely.
Does ClassCaller require building routines or habits?
No — that's the point. One-time setup (paste your Canvas calendar link, verify your phone, pick times), and it runs itself. There's nothing to check, update, or remember. The system works on your worst executive-function day, not just your best.
Is there a free version?
Yes — 3 reminder calls a month free, forever, no credit card. Pro ($9.99/month) adds unlimited calls, escalating reminders down to 15 minutes before deadlines, and every voice and style.
