After issues, a popular app for checking blood sugar has been restored.

It had stopped working on some Apple devices after an update, causing distress to glucose monitor users.

A new version of the FreeStyle LibreLink app has been released which fixes the issues.

The latest version of the software should be upgraded as soon as possible, according to Abbott.

According to a BBC statement, the company apologized for the inconvenience caused by the issue. “We appreciate your patience as we work on fixing it,” the company said.

The user wears a small sensor as a patch on their arm or belly, which transmits data to a mobile app. According to the company, their sensor-based glucose monitoring system is the most widely used in the world.

According to the NHS, 200,000 people in the UK use these types of sensors.

‘Very scary’

There was an online backlash on Friday against the FreeStyle LibreLink app.

Type 1 diabetic David Burchell told the BBC it was a “very scary experience”.

According to him, this equipment is meant to save your life. I woke up yesterday morning to a white screen and had a panic attack when I checked my sensor thing.

His company had removed the app from the App Store after Abbott told him to delete and reinstall it.

His only option was to use fingerprint testing, which he described as a “nightmare.”

Those without these sensors have to rely on finger-prick tests to monitor their glucose levels four to 10 times a day.

What is the app?

This app, developed by Abbott, connects to a continuous glucose monitor (CGM) – a white disc that covers a needle inserted under the skin.

A CGM allows Type 1 diabetics to continuously monitor their blood glucose levels – or blood sugar levels – without having to prick their fingers for blood samples.

When glucose levels are monitored in real time, people can make better-informed eating and exercise decisions.

Furthermore, it can notify the user or a family member if their blood sugar levels are too high or too low.

A CGM of Abbott stopped interacting with the LibreLink app of some Apple users, causing the problems.

According to Abbott, an update to the app has rendered the app inoperable for some users.

When these sensors aren’t available, people have to rely on finger-prick tests to monitor their levels.
