Collective Weight

Down 67 lbs and counting. Track every weigh-in, start challenges with your crew, and let a little friendly competition keep you showing up. Your goal, your people.

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 the pounds come off on a clean, zoomable trend 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 see who can drop the most body weight.

WHY YOU'LL ACTUALLY STICK WITH IT • Friends keep you honest. Group challenges, a live leaderboard, and a community feed mean someone always notices when you show up — and when you don't. • A little trash talk goes a long way. React, comment, and cheer each other on in every challenge's group chat. • Progress you can see. Your weight trend, weekly rate, consistency score, and goal projection update with every entry.

TRACK EVERYTHING THAT MATTERS • Daily weigh-ins with a beautiful long-term trend graph • Total lost, weekly rate, best streak, and consistency at a glance • An automatic projected goal date based on your real pace • Edit or delete recent entries anytime

CHALLENGES THAT MOTIVATE • Create private challenges for any group and any date range • Ranked by percentage of body weight lost, so everyone competes fairly • A live "progress race" chart of the whole group over time • Winners, medals, and bragging rights

APPLE HEALTH, TWO-WAY • Import weight, body fat %, BMI, and lean mass automatically • Weigh-ins you log are written back to Apple Health • Choose pounds or kilograms

STAY CONNECTED • Message friends directly • Per-challenge group chats with reactions • Achievements and streaks that reward consistency

Whether you're losing your first 5 pounds or your last 50, Collective Weight makes the journey social, motivating, and a lot more fun.

Weigh in. Compete. Lose together.
