Open-source weight and body metrics tracker, with support for Bluetooth scales
Note
On Google Play the openScale version is offered as an open beta.
For the latest development state, install the latest openScale dev build from the GitHub release page. Please be aware that the development version, may contain bugs, and will not receive automatic updates.
Monitor and track your weight, BMI, body fat, body water, muscle and other body metrics in an open source app that:
- has an easy to use user interface with graphs,
- supports various Bluetooth scales,
- doesn't require you to create an account,
- can be configured to only show the metrics you care about, and
- respects your privacy and lets you decide what to do with your data.
openScale has built-in support for a number of Bluetooth (BLE or "smart") scales from many manufacturers, e.g. Beurer, Sanitas, Yunmai, Xiaomi, etc. (see model list below). Together with our users we constantly improve and extend the set of supported scales and in many cases pick up where the original app falls short.
- Custom made Bluetooth scale
- Beurer BF105, BF500, BF600, BF700, BF710, BF720, BF800, BF850 and BF950
- Digoo DG-S038H
- Excelvan CF369BLE
- Exingtech Y1
- Hesley (Yunchen)
- MGB
- Medisana BS444, BS440
- Runtastic Libra
- Sanitas SBF70
- Silvercrest SBF75, SBF77
- Vigorun
- Xiaomi Mi scale v1 and v2
- Yunmai Mini, SE and X
- iHealth HS3
- Easy Home 64050
- and many more
Please see openScale wikipage for the full list and the level of support for each scale.
For scales without Bluetooth, or Bluetooth scales not (yet) supported by openScale, measurements can be manually entered in a quick and easy way.
Weight, BMI (body mass index), body water, muscle, LBM (lean body mass), body fat, bone mass, waist circumference, waist-to-height ratio, hip circumference, waist-hip ratio, visceral fat, chest circumference, thigh circumference, biceps circumference, neck circumference, body fat caliper, BMR (basal metabolic rate), TDEE (Total Daily Energy Expenditure), Calories and custom metrics. Each entry can also have an optional comment.
Note: don't worry if you think the list is too long: metrics you don't use can be disabled and hidden.
- Resizable widget to show the latest measurement on the home screen
- Configure your weight unit: kg, lb or st
- Set a goal to help keep your diet
- Displays all your data on a chart and in a table to track your progress
- Evaluates measurements and gives a quick visual feedback to show you if you're within or outside the recommended range given your age, sex, height etc.
- Import or export your data from/into a CSV (comma separated value) file
- Supports body fat, body water and lean body mass estimations based on scientific publications. Useful if your scale doesn't support those measurements.
- Support for multiple users
- Support for assisted weighing (e.g. for babies or pets)
- Support for people with amputations
- Partially or fully translated, see weblate project site for the full list
- Optional dark theme selectable
This app has no ads and requests no unnecessary permissions. The location permission is only needed to find a Bluetooth scale. Once found the permission can be revoked (or never granted if Bluetooth isn't used).
openScale doesn't send any data to a cloud and not having permission to access the internet is a strong guarantee of that.
If you want to synchronize your openScale measurements with external services, you can install openScale sync.
Before asking, please first read the FAQ, the openScale wiki and try to find an answer in existing issues. If you still haven't found an answer, please create a new issue on GitHub.
