Not what I expected.

This app shows you what the pump would look like, but does not give you a realistic experience with it at all. You can’t actually simulate doing anything.

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
