Stop texting each other the list.
A shared checklist for groceries, chores, packing, the party, and all the other things people need to remember together. Make the list, send the link; everyone you invite sees the same list on iPhone, Android, or the web.
You already tried the obvious ones.
Apple Reminders
Genuinely good, right up until someone in the house has an Android. Then you are back to screenshots.
Google Keep
Fine for a note. It was never really a list, and sharing one was clearly an afterthought.
Todoist, Asana, Notion
Built to run projects, with the onboarding to match. You wanted to buy milk.
Lists shouldn’t need a user manual.
Sometimes you just need to write something down, share it, and check it off.
Koinos gives you everything a shared list needs, without projects, dashboards, complicated permissions, or productivity-system homework.
That’s it. That’s the app.
Step 1: Make the list
Start from scratch or pick a familiar starting point: Groceries, To-do, Packing.
Step 2: Text them the link
They’re in. Free, on any phone, however many lists you put them on.
Step 3: Check it off
She checks off the bread; it leaves your phone too. Nobody’s holding an old copy.
Only the list-maker pays.
Whoever makes the list subscribes. Everyone they invite joins free, forever, and can do everything on the list that you can. Your partner, the roommate, the neighbor running the block party.
Nobody you invite ever hits a paywall. Inviting people costs you nothing, however many lists and however many people.
Groceries, chores, packing, the home projects: those live in one household space the whole family can see.
Everything else stays yours. Every family member has their own account and their own private lists; being in a family doesn’t make everything communal.
And the neighbor helping with the block party doesn’t need to join your family to join that one list. Invite them; it’s free.
A title and some checkboxes, until you need a due date.
Notes, dates, sections and assignees are there when you reach for them and invisible when you don’t.
- Organize longer lists with sections
- Jot a note on an item: “the blue one, not the green”
- Assign an item to someone
- Put a date on it when it matters
- Repeat the things that come around again
- Find that thing you know you wrote down somewhere
- Drag things into the order you actually shop in
- Undo it when someone deletes the wrong thing
- See what’s overdue, assigned to you, or recently changed
Make the list. Share the load.
From tonight’s groceries to next summer’s trip, keep everyone working from one simple, shared list.
