thank you harry. Good to know about the emergency startup

Hi Harry, and thank you. I was running iOS on an iPhone 6S. I tried to edit this post last night, but it was not listed nor available to me to edit. Last night, after I installed iOS 12, I re-tried Harry's Lap Timer. As it went through the conversion, I kept the screen and app awake, by continually ...

I tried to use my HArry's at WGI this past week. Apparently the latest upgrade requires that the lap and GPS data be converted somehow. It proceeds, then stalls (at record 203,000). Since i must go through this step before HLT opens, i could not use it. I cant even get int to delete the old data. HE...

I apologize is this is a duplicate, but i cannot find that this ever posted, and being a newbie to this, i'll assume i made an error. Here's the problem; I use Harry's in-car, iPhone 6S, latest iOS and HLT, for road/track data acquisition on normal circuits such as Lime Rock, Watkins Glen, etc. I mo...

Hi, I'm using Harry's in my track/race car. I have it oriented horizontally for proper video perspective (wider than high). Neither the interface nor the accelerometer readings rotate however, leaving me with meaningless lateral readings (and a weird interface). iPhone 6S with latest iOS. Can anyone...

The buttons sometimes do something. The flip horizontal moved it to (-1,0). All others did nothing or made little difference. This says to me that the only real data collected was that of gravity. Why? Also, even if true, a rotate should have moved the cluster 90 degrees, btu did not. I rearranged a...

first, i think i finally found the "buttons" - I assume they are those small blue graphics overlaid on the plot? They are not 100% clear. I expect two flip horizontal and vertical, another tow rotate left and right? I have tried to press them and they do nothing. My data for this run is a ...

Harry gave a great explanation of the variance that may come frm the data, but at first-order, i buy those numbers. Maybe its really 1.15-1.2, but let's start with: your car was on hot Nittos. C&D was on cold street tires. That's a gigantic difference right there. Using my Solo , I routinely see...

thank you harry. I will try both. I set the orientation stationary in the paddock. Its somewhat mysterious, some runs record properly. They rarely display properly in real-time while driving. Ahh well.
