PlankPact

What is PlankPact?

Before building PlankPact, we ran a simple experiment. We paired 14 strangers on WhatsApp and gave them one task: do a plank every day for 7 days. If your partner quits — you both lose. All 7 pairs completed the challenge. 3 continued on their own. That experiment became this app. Research shows we're more afraid of letting someone down than failing ourselves. That's the entire mechanic behind PlankPact.
