The shared habit tracker for two

Build habits,
together.

DuoDucks is a habit tracker you share with your favorite person. You both see who actually showed up today, and showing up earns credits you spend on rewards you invent for each other — breakfast in bed, picking Friday's movie, that kind of thing.

How it works

Three steps to your first reward.

01

Pick your habits

Add the habits you each want to keep. They don't have to match — maybe you're running while they're reading. Set a daily goal that feels doable.

02

Invite your person

Send them one link and they're in. From then on you're each other's accountability partner: you both see who actually showed up today, which is exactly the nudge most habits are missing.

03

Invent your rewards

Price them however you like: a foot rub, breakfast in bed, control of the playlist for a week. Show up, earn credits, treat each other.

Put it on your home screen

Two taps and it's an app.

DuoDucks lives in your browser — no app store, no download. Two taps and it sits on your home screen like any other app, opening straight into today.

That's it — DuoDucks is on your home screen.

On iPhone this only works in Safari — Chrome and Firefox don't offer it. Opened inside Instagram or Messenger? Use that app's menu to choose "Open in browser" first — in-app browsers can't install anything.

What you get

A habit tracker built around two people.

Daily and weekly habit tracking

Aim for every day, or set a weekly goal — say, four days a week — and rest days won't count against you.

Count it your way

Simple done / not-done checks, or measured goals — pages read, minutes stretched — with met, beat, and crushed stages for bigger days.

A calendar you can read at a glance

One month, every habit. Each day shows a little bar per habit, so a full row is a finished day and gaps show what slipped.

Credits for showing up

Meeting a daily goal earns credits into the balance you share with your partner. Bigger days earn more.

Rewards you invent together

A foot rub, breakfast in bed, winner picks movie night. Price them in credits and redeem when you've earned enough.

Accountability, not surveillance

You each see whether the other showed up today — read-only, with a You / Partner switch. Solo habits stay private and are just for you.

FAQ

Questions, answered.

Is DuoDucks free?

DuoDucks is currently free during its early beta, with no ads. If that changes, you'll see the price and terms before choosing whether to pay.

What is an accountability partner?

Someone who sees whether you did the thing you said you'd do — and whose progress you see in return. In DuoDucks you're each other's accountability partner: you both see who showed up today, which is usually all the nudge a habit needs.

Do we both need the same habits?

No. Your lists are completely your own — maybe you're running while they're reading. One of you can even join with no habits at all, purely as an accountability buddy.

Can I share it with a friend instead of a partner?

Of course. DuoDucks is a habit tracker you share with one other person — a partner, best friend, sibling, or gym buddy. Any duo works.

How do rewards work?

Meeting a habit's daily goal earns credits into a balance you share with your partner. You invent the rewards and set their prices — then redeem them when you've earned enough.

Can I track habits just for myself?

Yes. Solo habits sit alongside your shared ones, stay private, and don't earn credits. They're simply yours.

Does DuoDucks work on my phone?

Yes — it runs in your browser, and two taps put it on your home screen, where it opens and feels like an app. Nothing to install from an app store. The steps for iPhone and Android are illustrated above, and again at duoducks.com/install.
