Engine1 is meant to empower Type 1 diabetics to lead an active lifestyle. It is the first ever real-time decision support system for Type 1s and is almost like having a personal diabetes coach!

The Engine1 mobile and web apps are designed to give handy guidance, tips and info surrounding activity. Make activity-related decisions in real-time with ease. Be guided on good times to start exercise, quantity of food to be eaten during an activity session and the right intensity of exercise to maintain optimal blood glucose levels. Go prepared to your activity carrying along the re-fueling food that may be needed!

With easy ways to log and track your food, insulin, blood glucose and activity, Engine1 takes the guesswork out of how different factors can impact your blood glucose outcomes due to activity. When used over a period of time, Engine1 will help you identify what works best for your unique physiology and condition.

Engine1 can also read data from the Health app on your iPhone to bring in information such as blood glucose records, heart rate, distance covered and steps to give you more relevant visuals and information.

Once you sign up on the mobile app, you can also login to the Engine1 web app for deeper analysis, making it easy to spot trends associated with activity. Invite your family member or doctor to play Caretaker for you. Caretakers will be able to view your activity feed and charts on the web app and can provide you with helpful insights and observations. You can also choose to ‘live-share’ an activity for someone to monitor your exercise in real-time. This provides the recipient with live updates on alerts and events happening in the app during your activity.


If any of these lines sound like you, Engine1 is the app you need!

I wish...
• I could predict in what direction my BG is headed!
• I could exercise without the fear of going low or high
• I knew how much to eat before, during and after an activity
• I knew if it's a good time to start an activity now or later based on my insulin and food levels
• I knew how to better plan my insulin doses and timings
• I didn't have to eat so much to prevent going low during my activity.
• I wish I knew for which activities my blood sugar performs best versus worst.
• There was more timely information when I am doing my activity so I can better manage my BG
• I had an app that helps one do activity while also considering the Type1 condition

Customer Reviews

Not Intuitive

I had high hope for this app based on a review of the founder on Diabetes Mine. To unlock meal, insulin and bolus log, you need a subsription. This is a feature that is FREE or part of a single $2 app payment in most diabetes log apps. I don't see what value is unlocked for $10/month.

The app UI needs some work. The app hung or crashed on my 256 GB iPhone 7 which is running iOS 10.2. I could not figure out how to remove data from the log after making a mistake. After 20 minutes of poking around I found this in the health log.

The app uses a lot of technical gargon that I did not understand. What's a

It seems to me the app is designed to support the exercise coaching business of Gluoce Advisors and is not meant to be used stand alone.
