The whole product flow of apps for dexcom is amazingly stupid. Need to monitor you blood sugar? Oh you'll need to download the main dexcom G5 app--- oh and it's buggy as hell, you'll need to just reinstall it every so often just to get it to pair to a sensor. Need to share your numbers with needed family and docs? Oh--- you'll need a separate app for that... we call it the share app you'll need that first. Oh--- people that need the data? Yeah, there's a separate app for that too--- it's called follow--- and it to is buggy as hell, we can't really tell you when you'll get your data---maybe you will, eh maybe you won't---don't worry it's your cellular networks fault if you don't. Oh--- your doc needs to see your numbers and trend reports? Oh we've got ANOTHER separate app for that too--- dexcom sensors themselves are amazing in treating diabetes. However dexcom can now claim the title of DEATH BY 1,000 APPS. Integrate people.

Dexcom G5

Since the Dexcom G5 came out I have had nothing but issues with setting, pairing, lost signal, updates and Follow.
I would hope Dexcom will get their act together and get input from actual users on the app design and how it can be more user friendly.
One of the biggest issues is trying to get help from the technical support department. It is very frustrating to be on hold for hours when you need help. When you actually get connected to a person, in my experience they have no clue what your asking and how to help.
Make the app more user friendly, show glucose level on the app without having to open, re-right instructions so they are up to date with phones and their product and hire an train their technical staff (especially the weekend staff)!

Not functioning after update

If you're reading this and your system still works, DO NOT update the app. The last 2 updates have cut off all connectivity with share, prohibiting glucose levels to be monitored on my phone, watch, or being sent to any of my Share contacts. It says I have an invalid login, and when attempts are made to reset/fix my information, the app does nothing, and since there is no web interface in which to update this information, the app is the only option. Calling Dexcom for support I was only told it was Apples fault for updating their OS, but it worked fine for 3-4 days on the new OS, it wasn't until the app was updated that everything stopped working.
