What you get
Everything you need.
Nothing you don’t.
Built for real people doing hard things — not for fitness influencers tracking macros to the milligram.
End-to-end encrypted
Your weight is encrypted before it leaves your browser. The server stores scrambled data. Nobody — including the admin — can read your numbers.
Group leaderboard
Compete on progress, not numbers. The board shows weight change or % lost — never your actual weight. Friendly accountability without the exposure.
Private goals
Set a target weight or % loss, add a deadline, and watch your progress bar fill up. Your goal is yours alone — completely invisible to everyone else.
Charts that make sense
Weight, percentage loss, BMI, measurements — all charted with a 7-day average to cut through the noise. Dashed target lines so you can see where you’re headed.
Full body tracking
Log waist, neck, chest, hips, thighs, biceps, calves, and body fat alongside weight. See the whole picture, not just a number on a scale.
Works everywhere
No app to install. Works in any browser on any device. Saves your credentials to iPhone Passwords so logging in takes one tap.
How it works
Simple by design.
No complicated setup. No fitness jargon. Just log your weight and let GroupWeight do the rest.
Get your account
Your administrator sets up your account and sends you a temporary password. Change it on first login — your entries are encrypted with it.
Log your weight
Enter your weight each day or whenever you weigh in. Add measurements, notes, or just a number. Takes ten seconds.
Join your group
Enter an invite code to join a group. Choose whether to share your weight change or just a percentage — you decide what others can see.
Watch the board
The leaderboard updates as members log entries. Sort by progress, percentage lost, measurements, or streak. No actual weights, ever.
Privacy first
Your weight is yours. Full stop.
This isn’t a policy — it’s the architecture. Your data is encrypted with your password before it touches the server. There is no master key.
- Weight encrypted in your browser using AES-GCM before transmission
- The server stores cipher text — meaningless without your password
- Share weight delta or % only — impossible to reverse-engineer your actual weight
- Two-factor authentication and full session management built in
- Export everything at any time — your data leaves with you

The leaderboard
Progress, not numbers.
This is what your group sees. Changes only. Real weights are never shown, never stored in readable form, never shared.
