Tingling in the sense that you think the app might not work as described or that management are not up to it?
Very hard to bag it too much while you are still holding I know. Maybe back out slowly and quietly so nobody notices.
I didn't put enough into it to change my life but some did and it will probably change their lives. They (management) seem to be honest enough to me so Im giving them the benefit of doubt to get it right next time. Will see what happen I guess...good luck.
