PlankPact
The plank app where quitting hurts someone else too.
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.
Fitness has always been a love–hate relationship for me. On one hand, I know it’s good for me. On the other, my discipline has never been great. I start commitments with myself — running, push-ups, yoga, the gym — and sooner or later my routine derails.
This problem has been with me for as long as I can remember. I tried to solve it in every way I knew. I read motivation books like Atomic Habits, tested systems, tricks, frameworks. None of it really clicked. Those methods just weren’t built for how I actually live.
Then one day, a simple idea appeared. I suggested to a friend that we do a 7-day challenge. Every day, we would do a plank — any duration, no rules — and send each other the time on WhatsApp. If someone forgot, we’d remind each other. No pressure. Just presence and support.
We started. And something unexpected happened. Almost overnight, my routine finally had a place to land. We finished the 7 days. Then we extended it by another 7. Then another. Neither of us wanted to disappoint the other person. The support, encouragement, jokes, and small check-ins made it easier — even on hard days.
That’s when I realized I had stumbled onto something important.
I wanted to know if this worked only for us — or if it worked for others too. So I ran a test. I gathered a group of strangers online, paired them up, and asked them to do the exact same thing for 7 days, using WhatsApp.
Every single pair finished the challenge. No one quit. Two pairs kept going for weeks.
The feedback surprised everyone — including me. People couldn’t believe that for the first time in their lives, they completed a fitness challenge — and actually enjoyed it. Friendships formed. It felt light. Human. Real.
That was the moment I knew Plank Pact had to exist. And now, you can be part of that story too.
I need to write explanation to people who voted for my product and don't see their votes.
I was also very suprised... and angry.
I asked them why.
Hi,
This is expected behavior on Product Hunt: one upvote does not always equal one point, and totals can fluctuate as votes are processed and reviewed for authenticity.[1]
So if 40 friends upvoted, it's normal that only 4 points show, because points are weighted and suspicious or inauthentic activity can be filtered out (for example, lots of new accounts created just to upvote, or patterns that look automated).[2][3]
For next time, the best approach is to share your launch and encourage genuine discussion, rather than asking people to upvote, since that can trigger filtering.[4]
Does this help clarify what happened with your votes?
I find it very unfair. I wrote e-mail to them.
Hello,
I hope this message reaches the people responsible for decisions on Product Hunt.
Today my product was listed. For the last 3 days, I’ve been actively engaging my community. Today, I sent an email to around 4000 people from my mailing list — people who use my services and products, my students, and my followers.
In the email, I asked them to register on Product Hunt and upvote my new app. They were already familiar with it, as I had been sharing the story behind it for several weeks. I put a lot of effort into activating this group, as well as my friends on Facebook who follow my journey as a founder and support me. They were also asked to visit the page, register, and upvote — and many of them told me they did.
To my surprise, only 4 votes were counted as legitimate. How is that possible? This does not feel like the kind of fairness you aim for. I understand the need to prevent bots and spam, but this is not the case here. These are real people from my community — people I personally asked for support — and now they are checking the results and seeing only 4 votes.
I feel genuinely frustrated. I can stay calm when many things go wrong, but I find it very difficult to accept situations that feel unfair.
I kindly ask the Product Hunt team to take a closer look at the votes on my product. I can provide proof that these were real users from my mailing list, as well as the promotional materials I shared with them.
At the time of voting, their votes appeared to be counted. They did not receive any message indicating that verification was required — and I believe many of them would have completed it if prompted, as they were genuinely motivated to support me.
I would really appreciate a clear explanation of why this situation occurred, and I kindly ask you to review and recount these votes.
Best regards, Jarek Kaniewski Founder of PlankPact
