How it works
From a passing thought to your weekly plan.
It becomes a note
Your words are transcribed and organized — with a label, a priority, a time or a place.
Reminded at the right moment
At the right time, or when you arrive at the right place. The engine learns your rhythm and picks the moment you'll actually act.
Features
One quiet app for everything you'd otherwise forget.
Not screenshots — the actual pieces of the app. Go ahead, try them.
Pay the electricity bill
Call grandma this weekend
Pick up the package — courier branch
Notes that sort themselves
Colored labels, a 1–10 priority and smart ordering keep the important things on top — without you tidying anything.
✦ Tap one to complete it.
Tell it when — and where
Save a place once and “when I'm there” reminders just work — matched on your device, not on a server.

Privacy
Your notes are yours. Full stop.
