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 isn't laziness or carelessness — your brain genuinely doesn't feel time passing. A clock tells you what time it is. DuePal shows you how much time you have left. HOW IT WORKS Set the anchor points of your day once: 9:30 — Stand-up 12:00 — Lunch 14:00 — Focus block 17:30 — Wrap up 18:30 — Pick up kids DuePal counts down to the next one, live. When it arrives, the countdown hands over to the next on its own — no timers to restart, no alarms to set again. Add a start time and a progress bar fills as the window runs out. ALWAYS IN SIGHT • Lock Screen Live Activity and Dynamic Island, with a Skip button • Home Screen and Lock Screen widgets in every size • Apple Watch app with complications • Control Center control, Siri and Shortcuts You never have to remember to check. The countdown is already there. A HEADS-UP BEFORE EVERY SWITCH For ADHD brains the hard part isn't the task — it's switching. Get a heads-up minutes before each due, then a reminder when it arrives. On iOS 26 and later, dues can ring as real system alarms, even in Silent mode. WORKDAYS AND PUBLIC HOLIDAYS Weekday dues skip your country's public holidays automatically — 20 countries and regions supported, including make-up workdays in mainland China and Taiwan. Skip a single day off with one tap. COUNTDOWNS FOR THE DAYS AHEAD Weekend, payday, the next public holiday, birthdays, trips and exams. Pin the one you care about to the top and to your widgets. MADE TO BE READ AT A GLANCE Six clock styles, from a flip clock to a progress ring, and twelve color themes. High contrast, large numbers, no clutter — you should know how much time you have in under a second. QUICK TO SET UP Start from routine templates or a quick 25-minute timer. iCloud keeps your dues the same on iPhone and iPad. WHO DUEPAL IS FOR Adults with ADHD who lose track of time between meetings and tasks. Students who miss class changes and study blocks. Parents juggling school pickup, meals and bedtime. Anyone who has set a 15-minute timer and been shocked when it went off "already." WHY NOT A REGULAR TIMER A timer counts a set length, stops at zero, and has to be started again every time. DuePal counts to the times of your whole day, repeats on workdays, knows your holidays and moves on to the next thing by itself. FREE AND PREMIUM DuePal is free to download. The free version includes one due, two countdowns of your own, the Live Activity, Dynamic Island and the Current Due widget. DuePal Premium adds unlimited dues and countdowns, Ring as Alarm, public-holiday skipping, the Apple Watch app and complications, the Countdowns widget, and every clock style and color theme. Choose a weekly or yearly subscription (the yearly plan starts with a 3-day free trial) or a one-time lifetime purchase. If you bought DuePal before it was free, Premium is already yours.

Some things in life don't fit on a calendar. Your driving license expires in 14 months. The internet contract renews in March. That annual insurance payment is coming up. The passport needs renewal before your trip next year. These aren't meetings. They aren't appointments. They're the quiet deadlines that slip through the cracks — until it's too late. TimeFlow puts your life on a timeline. Every deadline appears as a colored pipe on an infinite scrollable timeline. Pinch to zoom between days, months, and years. See everything at a glance — what's due this week, what's coming in six months, what you handled last year. Why TimeFlow instead of a calendar? Calendars are built for days and weeks. TimeFlow is built for the big picture. Zoom out to see your entire year. Zoom in when a deadline approaches. Your life admin, visualized. Features: - Infinite scrollable timeline — past and future, no limits - Three zoom levels — switch between days, months, and years with a pinch - Color-coded categories — organize by type (Personal, Finance, Health, Documents) - Multiple reminders — set alerts days, weeks, or months in advance - Overdue tracking — dedicated tab shows what needs attention now - Auto-dismiss — automatically clear past events on app launch - List view — switch to a grouped list when you need a quick overview - Quick search — find any event instantly by title, notes, or category - Recurring events — annual renewals, monthly payments, set once and forget - Home screen widgets — see upcoming deadlines without opening the app - Import & export — bring events from your calendar or share as ICS files - Dark mode — easy on the eyes, day or night - Hebrew & English — full RTL support Perfect for tracking: - License and passport renewals - Insurance and subscription payments - Contract end dates and renewal windows - Warranty expirations - Medical checkups and vaccination schedules - Tax deadlines and financial milestones - Vehicle inspections and maintenance - Membership renewals - Any deadline that matters but doesn't belong on a daily calendar Your life has more structure than a calendar can show.
