Team Mode — The Social Contract

Your apps are tied to
their step count.

Solo streaks break quietly. Teams don't. In team mode, every teammate must hit their daily goal before anyone's apps unlock — so when you sit down, you're not just blocking yourself. You're blocking your best friend's group chat.

Today's team

Three of you have finished. Sam is 1,800 steps short — and everyone's Instagram stays locked until those steps land. Expect a very motivating text.

How it works

Tie in. Walk. Unlock.

Step 01

Pick your poison

Choose the apps that eat your day — social, video, games — and set a daily step goal that stretches you. They lock at midnight.

Step 02

Tie in with your team

Invite the people you'd hate to let down. One shared rule: nobody's apps unlock until everybody hits the goal. Or go solo — the lock still holds.

Step 03

Walk it off

Your steps count themselves — phone in pocket or watch on wrist. When the last teammate hits the goal, everyone's apps spring open at once.

Why it sticks

Willpower fails.
Friends don't.

Every screen-time app asks you to police yourself. Doubleknot changes the game: your unlock depends on people who will absolutely knock on your door and call you out in the group chat.

Accountability works

A meta-analysis of 138 experiments (N ≈ 20,000) found that monitoring goal progress reliably boosts attainment — and reporting progress to others amplifies the effect.

Reclaim your day

Nielsen clocks US adults at over 11 hours a day listening to, watching, reading or scrolling media. Doubleknot trades the worst of it for daylight and movement.

One habit, two wins

Less doomscrolling and more steps — with fresh air thrown in free. Just two hours a week outside in green space is linked to significantly better health and happiness. No streak-shaming — just walk.

Be happier

In a randomized experiment with 2,743 people, four weeks off Facebook measurably increased happiness and life satisfaction — worth roughly 25–40% of the benefit of therapy — and people kept scrolling less after it ended.

Questions

Before you tie in

What if a teammate just… doesn't walk? +

That's the point — and the pressure works both ways. Teams set their own goal levels, and there's a built-in "rescue" option a limited number of times per month, so one bad day doesn't sink the team. But mostly? People walk. Nobody wants to be the reason four friends can't open Instagram.

Can I play solo? +

Absolutely. Solo mode locks your chosen apps until you personally hit your goal. Many people start solo and bring in friends and family once they feel the difference.

How does it count steps? +

Doubleknot reads steps directly from Apple Health, including from your Apple Watch or Garmin. No extra tracker needed, and your health data never leaves your device except the daily goal-met signal your team sees.

Can't I just delete the app to cheat? +

Doubleknot uses the platform's screen-time frameworks, which make quick workarounds deliberately annoying — and in team mode, cheating shows. Your team sees goal status, and the social contract does the rest.

When does it launch, and what does it cost? +

Early access rolls out to the waitlist first, on iOS. Doubleknot is €1.99/month or €10/year — and joining the list is free and commits you to nothing.
