Pick a goal, a schedule, how you'll prove it, and how much each person stakes.
Bring friends close enough that missing a day actually stings.
Everyone draws their signature on the rules before day one. The challenge starts only when the whole group has signed.
Each person adds a card or Apple Pay. If the streak breaks, the stake is charged automatically.
Submit proof in-app — live photo, timelapse, Apple Health, GPS, or screen time.
The group streak only advances when every member submits proof that day — or on whatever schedule the challenge uses. Make it to the end together and nobody is charged.
If one person misses, the streak ends. Every member is charged their full stake — and we keep all of it.
In a small group, people often increase their effort when they know the outcome depends on them. On Streek, the group streak advances only after every member checks in, so each person's follow-through is visible and essential.
Seeing someone pursue a goal can make that goal feel more immediate and achievable. Every verified check-in gives the group visible momentum, encouraging everyone else to act.
People generally work harder to avoid a loss than to gain an equivalent reward. A shared streak and money at risk give skipping a concrete cost, making follow-through harder to dismiss.

Nobody is charged when you join. Everyone links a card or Apple Pay up front, but nothing leaves your account unless the streak breaks. Finish the challenge and nobody pays.
Your group chooses how members will prove each check-in:
Proof must be captured or connected through the app. Camera roll uploads don’t count.
Day one begins only after every member has signed the commitment and linked a payment method. Until then, the streak hasn’t started.
Groups stay between 3 and 8 people. Invite friends from the app. They don’t need to already be on Streek.
Yes. The group leader chooses the goal, schedule, proof type, stake amount, and length before anyone signs.
