I first used the HRP Slips at the HRP track on Friday, January 29th. It seemed to work ok that evening. I put in my car number and it showed all my runs and my friend's runs as well. Today, Monday Feb 1st, It will not show my runs. I can see my friend's runs but they are incomplete and do not show all his runs. As of now, I can give it only one star. When it operates as it should, It rates at least 4 stars. my car 4010 friends car 4016 Android v. 11

I see your car and your friend's car runs under car# 1410 & 1416 and not #4010 & #4016. You just entered the wrong car numbers. There's nothing wrong with the TimeSlip app. If you enter the right car numbers, you will see all your timeslip details. Can you re-adjust the star rating?
