I just got a new smartphone...has anyone found a diabetes/bloodsugar app that is user friendly (my phone is smarter than me) and helpful?  Thanks.

I like the Track 3 Diabetes app.  Think it's $6.  I mostly use it to track blood sugars and look up and track carbs.  Foods or meals that you eat often can be added to the favorites.  

Only downside is that it doesn't have good reports. On my phone it will show you cool pie charts and bar graphs of blood sugar levels, but the results that are sent via email are a  difficult to read, chronological list of what's been entered.  

Track 3 is still the best app I've found.
