App is good enough for my purposes, but needs improvement

The app displays my sugar accurately enough (usually within 0-15 off) and works on my iPhone without crashing. One thing that I would like the Dexcom app engineers to reconsider is how the urgent low alarms work. I am in a situation where I need my phone turned on, but all noises and vibrations to cease. This app put my in a very embarrassing situation in front of my boss’s boss; to make a long story short I ate my glucose tablets and corrected for my low sugar before attending the event mentioned, but the urgent low alarm went off 3 times during his speech before I had a chance to turn it off. Please for the love of God let us silence those low alarms completely. I understand the liability aspect, but putting a simple disclaimer would prevent any potential law suits. Thank you for reading.

Great information but.......

I love this app, used it all the time to track Average +/- the Standard Deviation. However, for the past 5-6 months I’ve been unable to use it, login information is not recognized. Called tech support several times to work with me resetting the password, etc. but to no avail. Periodically use the website version but that too has been difficult, at times. I have found the given information is extremely useful keeping my A1C around 6-6.5

iPad Support? Nope! Useless features? Sure!

The useful bits of this app would be perfect for native iPad support for the same reasons you don’t usually paint or write music or essays on your phone. I want to see everything. Instead I get to see very little.

I have no idea why the "percentage while you were in range metric" is even there, much less why it gets top billing. I think it’s worse than useless in the same way frequently measuring how much you weigh gets in the way of losing weight. It doesn’t tell you what you are doing right and what you are doing wrong. It doesn’t help you understand how to do better. It only needlessly adds complacency that you are doing good enough or anxiety that you aren’t doing good enough. It doesn’t tell you why your diabetes does what it does which is kind of the point of a continuous glucose monitor.
