Diabetes management is a daily effort of maintaining glucose levels
Glucose Buddy is a free app from Azumio. You enter your glucose numbers, carbohydrate consumption, insulin dosages and activities and monitor them throughout the day on the app or you can do the same on the free account online - which is great for older diabetics who do not have a smartphone or tablet.
You can also view and print charts that show your glucose levels.
The app is available for iOS and Android. http://www.glucosebuddy.com/
