Summary :clipboard:

Monitor and track your weight, BMI, body fat, body water, muscle and other body metrics in an open source app that:

Supported Bluetooth scales :rocket:

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.

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.

Supported metrics :chart_with_upwards_trend:

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) and Calories. 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.

Other features :zap:

Privacy :lock:

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 synchronise your weight to GoogleFit and/or MQTT 3.1, you can install openScale sync from GooglePlay.

Questions & Issues :thinking:

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.
