If the blood glucose level is higher than normal but lower than the prescribed level for diabetes, it is called pre-diabetes or border line diabetes. Pre-diabetes results in blood sugar levels that are higher than normal.

This increases the risk of developing type-2 diabetes. However, this condition can be improved with a healthy diet and exercise. And so Apple is creating an app to keep iPhone users safe from diabetes. The app will teach different strategies for blood sugar control as well as help measure the calorie content of food.

Apple has long been rumored to be working on blood sugar or glucose measurement technology. Although no specific information is known about this, Bloomberg reported in a report that Apple is developing an app for people with pre-diabetes. The app will help any person to control their blood sugar level by providing various information. The app has already been tested on several Apple employees.

The main purpose of this Apple app is to help monitor the increase or decrease in blood sugar levels along with people's eating habits. For example, a high-carbohydrate meal raises blood sugar, while adding some protein to that meal keeps blood sugar under control.

Demand for metabolic health tracking devices for pre-diabetes and others is increasing in the market. Recently Dexcom and Abbott have launched special glucose monitoring systems for people who are not dependent on insulin. Startups like NutriSense and Levels are also working on the use of glucose monitors to understand the impact of their customers' weight control, sports or diet. In keeping with these trends, Apple is also working to bring blood sugar measurement apps.
