I do not know why this is bugging me so much but it is.

MyFitnessPal is great for recording my diet, It just works and I love it.

Samsung Health keeps track of my steps and exercise.

Accu-Chek tracks my blood glucose levels through my Guide meter.

Now for my problem, I want them all to talk to each other. Yes, I can manually input the data but I am trying to find a solution that will allow them to just sync.

Samsung Health comes the closest. It pulls my nutrition info from MyFitnessPal and is supposed to sync with Accu-chek but it doesnt. I have hunted but cannot find a reason it is not syncing.

I have looked at into MySugr app and Diabetes:M and they do not appear to be any better at syncing with data. both claim to sync with Accu-Chek but are dubious when it comes to MyFitnessPal and/or the fitness stuff.

I am using Android, Samsung Note 8. Do you guys know of an app or something I may be doing wrong?

Ok, so the Accu-Chek Connect app was just uninstalled from my Note 8. Evidently it is no longer "compatible with my device"

So I just connected and synced my device (Accu-Check Guide) with mySugr app. It also connects to Google Fitness. And both seem to be working well with it.
That just leaves MyFitnessPal but really I can just pull the total carbs at the end of the day and input that into mySugr.

Maybe that is the best solution for now.
