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.

Sensor life.

I am currently going to replace my forth sensor failure short of it’s ten-day life. Although the DEXCOM tech people have been absolutely great with replacing them, this still a somewhat disturbing event. It is now March 29 (my current sensor was due to expire on March 31 at around noon); I started using the DEXCOM system on February 2 and in this short time experienced four sensor failures, it seems a bit much. If I’m doing something wrong, I can’t imagine what that can be, it’s not rocket science...you stick the sensor applicator to you and push the button. I even apply an overpatch. Simple.
This all being said, with the exception of the above, I’m very satisfied with the DEXCOM System and it's potential to help me with my diabetic problems. All DEXCOM techs and personnel I speak with on the phone have been great. Will call again here shortly.....

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
