The strongest fact
On Android, WeekScale isn't even granted internet permission.
There is no account, no proprietary cloud sync, no advertising, analytics, or remote crash-reporting SDK — the iOS app makes no direct network requests, and your weight history lives in the app's private storage on your device. It only leaves when you choose to export or back it up.
The only thing it rewards
No goal weight.
No verdict on the number.
WeekScale will never have a goal weight. There are no badges for losing, no celebrations for reaching a target, and no guilt for gaining. The only thing it positively reinforces is showing up: how many times you weigh in during a week. Read why
- Five or more weigh-ins earn the week its green card
- The Reliability Score shows how much to trust a week
- The only prize is a more complete week
The weekly view
A finished week stays finished.
And can be compared.
Each calendar week has an end, so it stays finished and can be compared fairly with another. Unlike a moving average, it does not rewrite yesterday's answer. A fixed week can come up short through missed days, a partial first week, or travel, so WeekScale shows how complete each week is. Why calendar weeks matter
Counted days, not judgment
The Reliability Score counts how many of the seven days hold an entry — one day is 14%, five is 71%, all seven is 100%.

What's next
A small app, with a deliberate plan.
The roadmap is shaped by beta feedback and is mostly UI-focused right now. After that, the plan is to sync from Apple Health on iOS and Google Health Connect on Android — reads only from your device. See the plan
