Does it track streaks?

No. A daily card comes back each morning and you drag it to Done; the Done column is the record. There are no charts or badges on purpose.

Can we each have our own habits on the same board?

Yes — give each card an owner. The Show only mine filter gives each of you a clean view.

Is it good for ADHD body doubling?

Many people use it that way: a repeating “work session” card you both own, plus the Today filter so only today's cards are visible.

Does the other person need to pay or install anything?

No. They open your invite link, type a name and an email, and they're on the board. Installing it as an app on their phone is optional. Simpleban is free forever for two: you and the one person you invite get every feature, unlimited boards and cards, no trial and no credit card. The promise is written into the Terms: nothing that is free today will ever move behind a paywall, and your +1 never pays. If you need more people or want to share boards beyond your +1, we'll soon introduce subscription tiers — a flat rate, never per seat.

Accountability

An accountability partner app for two people

Updated 20 October 2026 · by the Simpleban team

In short

An accountability partner works for one reason: someone can see whether you did the thing. Simpleban is a free shared kanban board for exactly two people where each person's habits are repeating cards (“Write 500 words — daily”, “Gym — Mon/Wed/Fri”) and goals are cards with due dates. A done habit is dragged to Done; an undone one just sits there, visible to both of you, and the 8am email lists it. A repeating Sunday check-in card, alternating between you, keeps the weekly conversation on the calendar.

Simpleban, a kanban board for two people: a shared “Our home” board with This week, Doing, Waiting and Done columns, cards marked Mine or assigned to a partner, due dates, repeating chores and a moving-day countdown.

How to set it up

Each person adds their own habits as repeating cards and marks them mine.
Add two or three goals with real due dates. Mine, yours.
One card: “Sunday check-in — 15 min call”, repeating weekly, alternating who books it.
Body-doubling for ADHD? Make the session itself a repeating shared card and both show up to it.

How it works

Every card has an owner: you, your partner, or either of you — so “who is on this?” is answered before anyone asks.
Hand a card to your partner and it moves to the top of their board under “waiting on you”. If they're not on the app, Simpleban emails them a few minutes later, and the next morning's 8am email mentions it once if it's still waiting — never every day. You never press a “remind” button.
When your partner is done, they hand it back and it reappears at the top of your board.
Repeating cards come back on their own schedule — daily, weekly, chosen weekdays, every N days, monthly — and can alternate between the two of you.
Due dates with a calm Today / This week filter, a private calendar feed for Google, Apple or Outlook, and a countdown on the board for the date that matters.
Notes, checklists and comments live inside each card, so the context travels with the task.
Your partner joins from your invite link with a name and an email — no password, nothing to pay. Both of you have the full app on your own phone; it installs like an app and works offline for reading.

What it is not

No streaks, badges or charts. The feedback is the board: a column of Done that fills up, and a card that didn't move. For some people that's exactly the right amount of pressure.
