App Sucks!!! Don't buy the G6 if you want to use your smart phone; it crashes to much. My co-worker (we have identical phones / Employer provides) has the Libre FreeStyle and has no issues with phone connection. I purchased the G6 based on Medical reviews. I like the system but very disappointed in the lack of App technology in a technology driven world! Not Upset with the G6, just the phone app!
