A T2 with the right meter could have their glucose data saved automatically as well. I hope the app could allow manually entering data as well. What the app computes (daily or rolling averages, A1C?) is as yet unknown though.
Correct. For example, I've used the One Touch Verio Sync which already has an App and syncs directly via Bluetooth to my iPhone.
Current CGM receiver does not show averages or A1C. You need to plug in and sync with computer to see averages. A1C is a different story although it would be nice to see.
If you are T2 (or T1) you should check out Verio Sync. Good meter that spits out good info.
