The Withings BPM Connect and the Withings BPM Core have significant differences, which are summarised here:

## Measurement functions
- BPM Connect: This device is purely a blood pressure monitor for the upper arm that also measures the heart rate.
- BPM Core: In addition to measuring blood pressure and heart rate, the BPM Core can also measure the electrical activity of the heart (ECG) and respiratory rate.

## Design and portability
- BPM Connect: It has a minimalist design, is wireless and compact, which makes it easy to transport. The cuff can be wrapped around the plastic body.
- BPM Core: This device is also wireless, but it contains additional functions, making it slightly larger and more complex than the BPM Connect.

## Connectivity and data storage
- BPM Connect: It has Wi-Fi and Bluetooth connectivity to automatically transfer data to an app. It can store up to 8 users.
- BPM Core: Similar to the BPM Connect, it offers Wi-Fi and Bluetooth connectivity, but it typically stores the data for one user unless configured with an app that supports multiple users.

## Price
- BPM Connect: The price is typically around 110-130 €.
- BPM Core: It is more expensive and is typically around €230 or more.

## Additional functions
- BPM Connect: It offers colour-coded indicators on the display to classify blood pressure readings and indicates if the cuff is not fitting properly or the measurement has been disturbed.
- BPM Core: In addition to the basic functions, it offers additional health monitoring functions such as ECG and respiratory rate measurement.

These differences show that the BPM Core offers more comprehensive health monitoring, while the BPM Connect focusses on simple and accurate blood pressure measurement.
