Hello Angie,
First of all, don't feel like failing, Type 1 is hard to control and manage, especially during the teen years. believe me, ive been there.
I have tried out the IBG meter, it is something worth trying out, however i personally did not like it, because i had a bigger phone (with the meter attached to it). also, the meter showed results about 2mmol higher than usually, which is in my opinion quite a lot (36mg dl). however, this could also be a problem restricted to my meter, not the whole system itself. An app worth trying, but not combinated with a meter is mySugr.
Here is a discussion about apps to log BG's, you might wanna look at it:

I see your daughter is on a pump, so that is great. maybe reading think like a pancreas by gary scheiner or pumping insulin by john walsh might help you there, i have no idea how long you have been pumping or managing diabetes in general, so those are some things you can try out additionally to bring this a1c down!
Wishing you all the best
SC
