iCloud
Your data, your Apple Account.
The Log
One number a day. That's the whole job.
Tap plus, type the number, done. Entries group themselves by month so a year of weigh-ins reads like a diary instead of a spreadsheet. Swipe to edit or delete anything.
- Lbs or kg: switch any time, and your history converts with you.
- Optional weigh-in reminder to keep the streak alive.
- Back-date an entry you forgot.
The Dashboard
The trend, at the size it deserves.
Current weight, total change, BMI and entry count sit across the top. Below them, a full-width chart you can scope to a week, a month, three months, a custom range, or everything you've ever logged.
−8.0 lbs
Total change, always visible

With Friends
Everyone's lines on one chart.
Send one invite link. From then on, you and your friends or family see each other's progress side by side, with 7-day and 30-day change for each person, so encouragement lands at the right moment.
Invite by link
Tap Invite in the Shared tab and send the link however you like. They open it on their iPhone and they're in.
Mutual by choice
You see theirs once they share back. Nobody is added to anything without deciding to.
Change, not judgement
Each person shows their current weight and 7- and 30-day movement, the numbers that actually mean something.
BMI
A number, plus the context around it.
Your BMI updates with every weigh-in, and the full category scale sits right underneath so you can see where you land and what moves you. The app is honest about the limits: BMI ignores muscle mass, body composition, age and sex.
Informational only, not medical advice.
Privacy
There is no server to trust.
Your weigh-ins live in your own iCloud via CloudKit. We never see them, because there's nowhere for us to see them from. No account to create, no email to hand over, no analytics profile, no ads.

Questions people actually ask.
Why does it say "iCloud Required"?
Your data lives in your own iCloud, so the device has to be signed in. Sign in under iOS Settings, come back, and tap Check Again.
How do I share with a friend?
Shared tab → Invite → send the link. They see your progress when they open it on their iPhone, and you see theirs once they share back.
How do I restore Premium?
It's a one-time purchase tied to your Apple Account. On a new device: Settings inside the app → Restore Purchases. Family Sharing is supported.
My entries aren't syncing.
Check both devices use the same iCloud account and have a connection, then Settings → Refresh from iCloud. Offline entries sync next time you open the app online.
How do I delete my data?
Swipe any entry to delete it, or tap Settings → Data → Delete All My Data to permanently remove everything you've logged. You can also wipe residual iCloud storage from iOS Settings → your name → iCloud → Manage Account Storage.
