One shared system for two
The shared list always ends up being one person’s job. Not here.
Reminders, messages, notes, and calendar entries can capture the pieces. Someone still has to connect them, remember who owns what, and follow up. DuetFlow gives both of you one shared flow where every task is clearly one of us, both of us, or just mine. So it’s not all on one person anymore, and “I thought you were handling that” stops being a thing.
For the household organizer
Move the shared load out of your head without giving up the structure you trust. Keep private work private, and give every household responsibility a clear owner.
The system carries it.For the other person
See what is yours, what either of you can handle, and what is already done. You do not need to run the whole planning system to take part in it.
I know what I own.One source of truth for shared responsibilities. A private side for everything else.

The patchwork
Reminders, messages, notes, calendars. And one person still has to join the dots.
The tools capture fragments. They do not make responsibility clear.
A shared list works for a while. Then a handoff moves to chat, a recurring task lives in Calendar, a note becomes the real plan, and the list stops being the source of truth. Someone has to keep the pieces connected and notice what fell through.
That person becomes the household’s coordination layer: planning, assigning, checking, and following up on top of doing their own share. When responsibility is vague, work gets done twice, not at all, or only after another reminder.
The mechanic
Two of you in one flow, and everything in it knows who it belongs to.
Every task is one of us, both of us, or just mine, and your private side stays private.
This is the part a shared list can’t do. In DuetFlow, every task carries who it’s for:
- One of us: either partner can take it; first to do it, done. (The grocery run, the call to the plumber, whoever gets to it.)
- Both of us: each of you has your own to do. (You both RSVP, you both pack.)
- Just one of you: clearly owned, clearly visible to both, so it stops being a question.
And next to all of that, a private side. Your work tasks, your personal projects, the surprise you’re planning: they live in your space, and your partner never sees them. Make a task private and it leaves the shared household entirely; make it shared and it shows up for both of you. Same app, one flow, no second tool for “the couple stuff.”
No accounts to create for your partner, no company server in the middle. Just the two of you.

For the household organizer
Replace the patchwork without giving up the structure you trust.
Whether you are stretching Reminders past its limits or already run GTD, shared work finally gets the same reliable home as everything else.
You should not have to choose between a simple shared list and a serious personal system. DuetFlow gives the household clear ownership without flattening everything into chores:
- Inbox triage that won’t let a task escape half-baked: a shared task can’t leave your Inbox until someone actually owns it, so nothing drifts into the void unassigned.
- Today that’s actually today: defer dates, due dates, planned dates, and always-available work computed into one honest list, with anything blocked or waiting kept out.
- Upcoming as a 30-day rolling view, Waiting For grouped by who you’re waiting on, Someday for the maybe-laters.
- Sequential projects that block themselves: the next step doesn’t surface until the one before it is done, so a multi-step project stays a chain, not a pile.
- Project-inherited metadata and recurrence, so you set it once and the system carries it.
The household gets one dependable responsibility layer, while your work and personal projects stay on a private side your partner cannot see.

For the other person
A focused daily view, not another planning job.
Open DuetFlow, see what is yours or available to either of you, and get on with the day.
You do not need to manage the household system or learn every GTD concept. Your daily view stays focused, while the shared flow still makes each handoff explicit.
- See only what’s yours. Flip one filter to “Mine” and the household noise disappears: just your tasks, nothing to wade through.
- Things get handed to you cleanly. When something’s yours, it’s clearly yours, not a vague “can you maybe handle this?” you have to remember on top of everything else.
- Less chasing and fewer check-ins. Because the app knows who owns what, both of you can see whether a responsibility is open or done.
- Your private stuff is yours. Anything you mark private, your partner can’t see, not even that it exists.
The point is not to turn you into the planner. It is to make your part of the shared system obvious, so responsibility can move without another conversation or reminder.

Why it exists
Built by a household that needed it. Used by that household every day.
DuetFlow runs our own actual life: one of us runs the system, one of us just wants it handled.
DuetFlow didn’t come from a market study. We built it because our own household had exactly this split: one of us lived in a serious GTD setup and tracked everything that touched both of us; the other never wanted a system and just wanted their part handled. Every shared-list fix we tried died the same way: one of us stopped opening it.
So we built the thing that actually works for two asymmetric people, and we’ve run our real household in it ever since: the groceries, the appointments, the projects, the private work each of us keeps to ourselves. The “one of us / both of us” model, the private side, the calm partner view: we run all of it on ourselves every day. It’s how we get through a week.
When something doesn’t survive a week in our own household, we cut it before it ever reaches you.
The two of us — the household DuetFlow runs every day.
Private by architecture
Private actually means private, because of how it’s built.
No DuetFlow server. No DuetFlow account beyond the Apple IDs you both already have. The app is designed so its App Store privacy disclosure can say “Data Not Collected”: your task data never reaches us.
Most couples apps put your “private” tasks on the same server as your shared ones and ask you to trust a toggle. DuetFlow doesn’t have that server. Your private tasks live in your own iCloud space; your shared household travels directly between the two of you through Apple’s sharing. Nothing routes through us, because there is no “us” in the middle.
That’s why our planned App Store privacy disclosure is “Data Not Collected.” It follows from how the app is built: we can’t see your tasks because they never reach a place we could look.
For the operator, that means your work and personal projects stay genuinely yours. For your partner, it means the surprise you’re planning, or anything you’d rather keep to yourself, is yours alone, with no company holding it.

Before you ask
The questions both of you are about to ask.
Will my partner actually use it?
That is the key question the private beta is designed to test. DuetFlow gives the second partner a focused view of what is theirs or available to either person, without requiring them to run the whole GTD system. Both people still need to agree to use it; DuetFlow makes that daily habit lighter, not automatic.
Is this real GTD or a toy couples app?
It’s real GTD: Inbox triage with blockers, Today, a 30-day Upcoming, Waiting For, Someday, and sequential vs. parallel projects with automatic blocking. It’s a system the operator can trust, and it happens to include a partner too.
How is this different from Apple Reminders or a shared list?
Apple Reminders already supports shared lists and assigning an item to one participant, and it may be all you need for a few clear tasks. DuetFlow is for households that need a fuller responsibility model: either of us, both of us, one named person, or fully private, plus Inbox triage, Today, Waiting For, and sequential projects.
Can I keep work and personal tasks private?
Yes. Your partner can’t see your private tasks, not even that they exist, because a private task leaves the shared household entirely instead of hiding behind a toggle on a shared server. Sharing is per task, not all-or-nothing, so the surprise you’re planning and your own work projects stay yours alone.
Can I bring my OmniFocus data over?
Yes, on the Mac. DuetFlow imports your OmniFocus data in three steps:
- In OmniFocus, locate your .ofocus file or a .ofocus backup.
- In DuetFlow on Mac, choose Import and pick that file.
- Review exactly what will be created before anything is written.
DuetFlow makes a backup of your existing data first. (Re-importing the same backup can create duplicates, and import is Mac-only.)
Is there a subscription?
We plan to launch without a subscription: a one-time purchase of 29.99 €, with Family Sharing for both of you on Mac, iPhone, and iPad. Final storefront price and availability will be confirmed before release.
Where does my data live, and is it safe if a device is offline?
Your data lives in your own iCloud, not on a DuetFlow server. Your private tasks stay in your iCloud space, and the shared household syncs directly between the two of you through Apple’s sharing. If a device is offline, your changes are kept locally and sync the next time it’s online.
Who is DuetFlow designed for?
DuetFlow is designed around two adults sharing responsibility for a household or family. It isn’t workplace team or project-management software.
Do we each need an account?
No. You both use the Apple IDs you already have. No new account, and no password for your partner to forget.
Can I use DuetFlow today?
Not publicly yet. Join early access and confirm your email to hear about the private beta and public launch. Joining isn’t a purchase or reservation, and you can unsubscribe at any time.
What platforms?
Mac, iPhone, and iPad, all native. There’s no web, Android, or Windows version. It’s Apple-only by design, and iCloud handles sync.
