OnU - The Lightest To-Do
Productivity
Free · Designed for iPad. Not verified for macOS.
You open a to-do app to jot one thing down. It asks: category? deadline? priority? You close it. OnU asks nothing. Free for 2 weeks.
You keep meaning to write it down.
But every app asks - by when? which category? what priority?
So you stop writing.
OnU asks nothing. Just write it.
JUST THE LIST. NOTHING ELSE.
You open a to-do app to focus. But there's a sidebar,
a calendar, tags, projects, filters, progress bars.
You came to clear your head. Now it's more crowded.
OnU shows you the list. That's it.
THREE TABS. THAT'S IT.
- To Do: what you're doing today
- Someday: everything else, no pressure
- Done: what you finished, quietly piling up
Check something off today, and at midnight it moves to Done.
Don't check it? It stays. That's the whole system.
NOTHING LEAVES YOUR DEVICE.
There's no server. What you write stays on your iPhone and Mac.
We can't see it. Nobody can.
iCloud quietly keeps iPhone and Mac in sync. No login, no account.
NO NOISE.
No notifications. No badge numbers. No streaks to break.
It's there when you open it, not before.
MADE BY SOMEONE WHO COULDN'T STICK WITH ANY OF THEM.
If categories and priorities are the reason you gave up on
to-do apps, this is for you.
PRICING.
Free for 2 weeks. $0.99 per month after.
If you stop paying, your data stays safe in iCloud. You just
can't open the app until you resubscribe.
No ads. No trackers. No data collection.
