Yes it’s different. It has 2 modes, manual and Auto. In manual mode, everything including programmed basals, temp basals etc is the same as Dash. In Auto mode the pod automatically raises and lowers basal every 5 minutes by getting a reading from Dexcom CGM.
It is easy to switch between modes. I have found a sweet spot of using manual mode before and after meals and Auto mode the rest of the time. So far so good.
