Diabetes management apps

No experience with any of these as I don't tend to use apps to manage diabetes. I do however use a Dario Smart meter that works with my smartphone and it's own app. There are built in facilities to enter your meals, carbs, insulin dose etc. I never use them, but they are there.

The two apps I tend to use are One Drop and Myfitnesspal (excellent carb counting). I believe One Drop also does carb counting, and it stores BG values. If you have an iPhone there is a good range of apps which link together using Apple Health, so one app can write the glucose logs and others can pick up on it.
