Legacy Flex Alert

Please ensure your device supports Bluetooth Low Energy (4.0) before downloading.

The Alfred sensor is a discrete innovative device that alerts patients as to how full their ostomy/stoma bags are so that they can decide if and when to empty them. The device sticks on to any ostomy bag sending Bluetooth alerts to an app on your mobile device telling you that your bag is filling up. You can set individual alerts as to when you wish to be notified. In addition this data is stored safely on our website allowing you to access it at any given time. Each device is single use only and lasts up to three months (see FAQs).

Important info: The information about the ostomy/stoma that the devices collects is for guidance only and is not intended for use in the diagnosis of disease or other conditions or in the cure, mitigation, treatment, or prevention of disease, or are intended to affect the structure or function of the body
