chance of reaching your goal with an accountability partner — versus less than 10% alone.
American Society of Training and Development (ASTD). ChallengeTies was built around that single insight.
A real person who knows if you showed up today.
Not an AI coach. Not an algorithm.
Every other habit app makes you responsible to a counter. We make you responsible to a person.
No complicated setup. Just you, a challenge, and someone who's counting on you.
Browse 100+ challenges across fitness, mindfulness, learning, creativity and more — or create your own from scratch.
Invite a friend or your partner with a direct link — or get matched with a motivated stranger. Solo mode available too.
Daily check-in. You see each other's streaks. You can't ghost without your partner noticing. That's the whole mechanism.
Everything designed around one truth: humans keep humans accountable.
Invite anyone via a direct link and track the same challenge together, every day. See your partner's progress in real time, chat inside your shared challenge, and view your complete shared history.
One number that tells the truth: are you someone who keeps their word? Your 30-day word-keeping rate out of 100, visible to your partner. It adapts to the pace you choose.
No friends available? ChallengeTies finds your ideal partner — same challenge, same life goal, same category, open to duo. Highest compatibility wins.
Ten categories, from a 5-minute habit to a full-year transformation. Durations from 7 to 365 days. Build your own and share them.
Earn trophies, protect streaks, climb global, national and regional leaderboards, and react to daily wins in the live Exploits feed.
English, French, Spanish, German, Portuguese, Italian, Arabic, Hindi, Chinese, Japanese, Korean, Russian, Dutch.
Real users. Real stores. Real words.
