Draw something in three seconds and it appears on your partner's home screen — no app to open, no notification to swipe away. Underneath sits everything a couple actually runs on: shared lists, reminders, plans, and the small rituals that keep you close.

The loop
The whole point is a widget on their home screen. A note you draw sits there until you send the next one — seen a dozen times a day, without either of you having to open anything.
A canvas, a handful of pens and colours, and whatever you want to say. Scribble, a heart, a bad drawing of the cat — three seconds is enough. Or start from a ready-made note when you're in a hurry.
One tap and it's gone. Notes are little artifacts, not messages: once sent they can't be edited, only replied to with another one. There's no typing indicator, no read receipt, nothing to perform.
The widget updates on their phone and stays there all day. They can react with an emoji or draw one straight back — and every note you've ever sent lives on the fridge door.
Features
A drawing canvas built for quick, warm scribbles — not a precision art tool. Your note is rendered exactly the same in the app, on the widget, and in the archive.
Every note you've sent each other, kept in one place to scroll back through. Free keeps the most recent 20; Premium keeps all of them.
Groceries, packing, the weekend. Both of you see the same list, and the interactive widget lets you tick things off from the home screen without opening the app.
Assign a reminder to yourself, to them, or to both. Repeating reminders and gentle nudges instead of nagging.
Anniversaries and countdowns, trips with their own packing lists and day notes, and repeating rituals like movie night — with a streak for keeping them.
One-tap pings — thinking of you, on my way, call me? — and Journey, a map of the places you've pinned together, built only from moments you choose to save.
