If you have ADHD, you know the feeling: you glance at the clock, it says 2:15. You look again — it's 4:47. Two and a half hours vanished. Your meeting started 17 minutes ago. This is time blindness. It's not about being lazy or careless. It's a neurological trait where your brain genuinely cannot feel time passing. Standard clocks and phone timers show numbers, but numbers mean nothing when your brain doesn't process duration intuitively. DuePal is a visual countdown timer designed specifically for time blindness. HOW IT WORKS Set your daily milestones — the anchor points of your day: 9:00 — Stand-up meeting 12:00 — Lunch 14:00 — Focus block 17:00 — Wrap up 18:30 — Pick up kids DuePal shows a persistent, always-visible countdown to your next milestone. Not a clock. Not a number of minutes. A visual countdown that your brain can actually feel — time shrinking in front of your eyes. When the current milestone passes, the countdown automatically rolls to the next one. Your day becomes a series of "time until the next thing" — which is exactly how time-blind brains need to process schedules. ALWAYS VISIBLE — EVERYWHERE The biggest problem with timer apps is that you forget they exist. DuePal solves this by putting your countdown everywhere you look: Dynamic Island shows your countdown without opening the app. Lock Screen Live Activities display time remaining right on your Lock Screen. You never have to remember to check. The countdown is always there. TWO VISUAL STYLES Flip Clock: A beautiful retro-style flip display that makes time feel tangible and physical. Numbers mechanically turn as time passes. Digital Display: A clean, high-contrast digital countdown for maximum readability. Choose whichever style your brain responds to. Both are designed for quick comprehension — you should know how much time you have in under one second of glancing. SMART REMINDERS Set alerts before milestones hit: 15 minutes before, 5 minutes before, or custom intervals. DuePal gives you transition warnings — because for ADHD brains, the hardest part isn't doing the task, it's switching between tasks. FLEXIBLE SCHEDULING Not every day looks the same. Set different milestones for weekdays, weekends, or fully custom schedules. DuePal adapts to your life instead of forcing you into a rigid routine. HIGH-CONTRAST DESIGN The interface uses bold, clear typography and strong color contrast. Designed to be readable at arm's length, across the room, or at a quick glance. No clutter, no decorative elements — just the information you need. WHO DUEPAL IS FOR Adults with ADHD who consistently lose track of time between meetings, tasks, and commitments. Students who miss class transitions or study blocks. Parents who need visual reminders for school pickup, meal prep, and bedtime routines. Professionals who experience time blindness during deep focus work. Anyone who's set a phone alarm for 15 minutes and then been shocked when it went off "already." WHY NOT USE A REGULAR TIMER Regular timers count down from a set duration — you have to manually start them for each event. They're for timing one thing. DuePal is for timing your whole day. It automatically counts down to your next milestone, then the next, then the next. No manual starts. No forgetting to set timers. Your schedule is always running. Regular clocks show what time it is. DuePal shows how much time you have. That's the difference that matters for time-blind brains. PRICING $1.99 — one-time purchase. No subscription. No free trial tricks. All features included. Time blindness isn't a character flaw. It's a real neurological difference that needs the right tools. DuePal is that tool.
