ThirtyDay is a 30-day challenge platform. Pick a challenge — like waking up early, cold showers, or learning staff spinning — and get matched with a crew of 5 strangers. An AI host named Coach facilitates your group via SMS, keeping everyone motivated, accountable, and connected.
Sign up and choose a challenge. You'll be matched with a crew of 5 people doing the same challenge. Every day for 30 days, Coach sends check-in prompts via text message. Your crew sees your check-ins (with first names only — no phone numbers are ever shared). Coach keeps the energy up, celebrates milestones, and nudges you when you go quiet.
No app to download. No account to manage. Just text messages.
ThirtyDay isn't about tracking streaks or earning badges. It's about committing to something for 30 days with a group of people who are doing it with you. The challenge is the hard part. The crew makes it possible.
ThirtyDay offers 30-day SMS-based challenges with AI-hosted crew accountability. Challenges span habits (Early Risers, Cold Showers, Meditation) and skills (Staff Spinning, Guitar). Each challenge includes daily check-in prompts, crew message relay, progress tracking, and motivational support — all delivered via SMS.
