Skip it alone. Do it together. DuoDone is a couple workout app where partners keep each other's workout promises. When you both finish today's workout, that's a DuoDone day. HOW IT WORKS · Invite your partner: make your own workout promise first, then send an invite link from the share sheet. Your partner connects with a single code. · Make a workout promise: pick gym, running, home workout, walking, Pilates, yoga, swimming, climbing, cycling or hiking, then choose the days and a deadline. Pinky promise! · Did you work out today?: post a proof photo, or just tap "Did it" without one. Need a break? Use a rest pass. · Your partner's cheer: your partner acknowledges your workout with one tap: . · Skip it and your partner knows: if there's no record by the deadline, your partner gets a heads-up and can send a cheer or a gentle knock. · Together for N days: days you both show up build a shared streak. Share it with a card. FUN BETS, NOT MONEY · Miss it and you buy the chicken. Keep it and you both go out for sushi. · Couple bets and penalties stay non-monetary: the dishes, a coffee, a massage, picking the movie. PROOF PHOTOS STAY BETWEEN YOU TWO · DuoDone is 1:1. You connect with exactly one partner, and there is no public feed. · Only your connected partner can see your proof photos. · Location data is removed from photos before upload. · Delete your photos anytime. If you disconnect, your partner can no longer see them in the app. You can report a photo you're uncomfortable with. ABOUT THE RESEARCH · A small study found that married adults who joined a fitness program with their spouse had a 12-month dropout rate of 6.3%, compared with 43% for married adults who joined alone (Wallace et al., 1995, Journal of Sports Medicine and Physical Fitness). · This is not a measurement of DuoDone's results. DuoDone turns the idea that you show up more when someone has your back into an app. GOOD TO KNOW · Bets are non-monetary only. · DuoDone does not guarantee weight loss or any other health outcome. Exercise at an intensity that suits your body. · Nodtry is now DuoDone. Your promises, history, and partner connection stay the same. · Contact: devhohouse@gmail.com ## Is DuoDone safe?
