Collective Weight

Collective Weight turns losing weight into something you actually look forward to, because you're doing it with your people. Log your weigh-in in seconds and watch your trend on a clean, zoomable chart. See your total lost, your streak, your projected goal date and exactly how far you have to go. Then make it interesting: start a challenge with friends, family or coworkers and race to lose the highest percentage of body weight. WHY YOU'LL ACTUALLY STICK WITH IT • Friends keep you honest. Group challenges, a live leaderboard and a group chat mean someone always notices when you show up, and when you don't. • Gentle nudges. A daily reminder at the time you choose, a Monday recap of where you stand, and alerts when your group is talking. • Progress you can see. Your trend, weekly rate, streak and goal projection update with every entry. CHALLENGES THAT MOTIVATE • Private challenges for any group and any dates; invite friends with a link or a 6-character code • Ranked by percentage of body weight lost, so everyone competes fairly • Your weight stays private: challenge-mates only see your % change • A live progress race of the whole group • Results, medals and bragging rights, then "Run it back" for a rematch in one tap WORKS EVERYWHERE YOU ARE • iPhone Duo: leaderboard and chat side by side when unfolded, tabletop logging, and seamless fold and unfold • Home and Lock Screen widgets • Apple Watch app and complications • Two-way Apple Health sync for weight, body fat %, BMI and lean mass • Pounds or kilograms STAY CONNECTED, SAFELY • Per-challenge group chats with reactions, replies and photos • Direct messages with friends • Block or report anyone in a tap Optional buy-ins are tracked for fun and settled between members outside the app. Collective Weight never collects or pays out money. Collective Weight is a motivation tool, not medical advice. Weigh in. Compete. Lose together.
