Good addition but could be improved!

I like being able to see what my pump is doing without digging it out. One problem is it doesn’t update as often with out me doing it. The app is set to update in the background.
It would be great if you could blouses from the app.
If these two issues were solved I would give it a solid five.

T Simulator bombs on launch

Was getting familiar with t-slim pump via your simulator program before deciding to purchase, on my Mac products using iOS 11. Apple just upgraded to ios12. Your simulator is incomparable with iOS 12. Have to quit learning your pump now, maybe this is a temporary problem?? Makes me think Tandem updates and upgrades are in jeopardy for Apple users in future Tandem improvements and compatibility issues. I would appreciate your input to your fix the current issue and also plans to prevent these issues in the future for us interested potential purchasing and users of your system. Thank you, Charles Trebnik
