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

Unio is built for two people, not for one person with a friends list. Most fitness apps start solo and bolt sharing on afterwards. Unio starts from the pair. You each get your own plan, built around your own goal and your own numbers, and you share one week, one streak, and one subscription. YOUR OWN PLAN, THEIR OWN PLAN Tell Unio your goal, which days you can train, and how long you have. It builds your week around you and rebuilds it when life gets in the way. Your partner gets theirs, built around theirs. One of you can be losing weight while the other is getting stronger. Lifting, home workouts, running, walking, cycling, the treadmill, the stair master, yoga and Pilates. TRAIN TOGETHER, LIVE Start a workout with your partner and watch each other's sets land as they happen, in the same gym or across town. Cheer them on mid-set, send a short clip, and get a nudge before your streak breaks. YOU DECIDE WHAT THEY SEE Weigh-ins, waist, chest, arms, weekly volume, body photos: every one is a separate switch, and you hold your own. Body photos stay off until you deliberately turn them on. Nothing is shared by accident, and turning something off stops it there and then. SHOW UP FOR EACH OTHER See the days you both trained, the streak you are holding together, and what your partner just finished, with their proof photo. Put both of your weeks on your Home Screen with the widget, and follow your own workout on the Lock Screen. TRACK WHAT YOU CARE ABOUT Pick the metrics that match your goal and ignore the rest. Losing weight, building muscle, getting stronger, building endurance, moving better or just being consistent: each one tracks different things, and Unio only shows you the ones you chose. FREE, AND WHAT COSTS MONEY Free forever: logging your workouts, your full history, weigh-ins, measurements, and everything you share with your partner. Unio Partner Plan covers BOTH of you. One of you pays and you both get the workout generator, week planning, exercise swaps, body impact, progress tracking, progress photos and accent colours. Start with a 1 month free trial, then $7.99 a month. Subscriptions renew monthly until cancelled. Cancel any time in Settings, under your name, then Subscriptions, at least 24 hours before the trial ends to avoid being charged.
