All I needed was a simple checklist before leaving home — keys, wallet, badge, umbrella. 30 seconds, then out the door. But the tools I found were designed for more complex scenarios. Project planning, team coordination, weekly reviews. Great tools for serious work, just not what I was looking for. I didn't need a system. I needed a list I could reuse every morning with one tap. There was another thing that bothered me. Tasks I'd added days ago would still be sitting there, unfinished, waiting. Some no longer mattered. But seeing them every time I opened the app gave me a feeling I couldn't quite shake. That quiet anxiety eventually made me stop opening it altogether. So I built 3DaysDo for myself — and for anyone who just wants something simple. No recurring setup. No analytics. No due dates. Add today's tasks. Tap a saved checklist to load it instantly. Check things off. 30 seconds. Done. If something isn't finished by tomorrow, you get a gentle reminder once. After 3 days, it quietly disappears on its own. No piling up. No guilt. Open the app tomorrow and it's a clean slate. Just today. Just what's in front of you. Features: • Today-only workflow — see only what matters now • 3-day auto decay — old tasks quietly disappear, keeping your list clean • Smart reminders — unfinished tasks get a gentle nudge the next day, just once • Reusable task bundles — save a checklist, load it in one tap, ready in 30 seconds • Carry-over triage — handle yesterday's leftovers simply, no piling up • Color labels — quick visual sorting, zero complexity • Home screen widget — check and complete tasks without opening the app • Daily reminders — build your planning habit • Subtask support — break bigger tasks into actionable steps • Multiple themes — make it yours • Local-only data — nothing leaves your device, your privacy matters 3Days Pro (unlock all premium features): • All premium themes • Unlimited task bundles • Extended subtask capacity • Advanced smart reminders — smarter reminder timing • Widget quick actions — complete tasks right from your home screen 3DaysDo — 30 seconds to set up. Then go live your day.
