3DaysDo

Always forgetting groceries—rewriting the same list every week. So I built 3DaysDo: save any checklist as a template, reuse in 1 tap. Overdue tasks auto-expire in 3 days.

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.
