I found a US link for you.https://www.ebay.com/itm/100Pc-Super...r=601680620703
You just site the magnet (which neodymium ) onto the front of the iPhone in the top RH corner.....as in where the lens sits on the back. If you can't follow that sorry I can't help further.

You might be onto something here. When I map the laptimer to the GoPro footage, Laptimer appears to be around 1 second out on a 2:45.lap of Spa.

Action cameras do not use optical image stabilization for good reasons. You need to use a camera that does not have optical image stabilization. Optical stabilization is really made for having a human hold the camera damping all the harsh shaking. When you firm mount it though, the hammers the optical stabilization hardware and produces worse video. Years ago I tried a Cannon HD camcorder and I even mounted it on a damped mount. The results were like an earthquake. You could even hear it hammer the camera in that case as the mechanism is much larger and heavier than a phone.
I finally just got a Garmin Virb Ultra 30 and never looked back. Sure, it is $399 but worth it. If you use Harry's Lap Timer to catch the overlays, you can get a good HD (or higher) action camera from Amazon for well under $100 these days. I believe you can then add Harry's data overlays to the action camera video afterwards.

Race logic ; VBOX.
completely idiot proof.
starts stops automatically on any track, take SD card out and all data and video is merged on laptop and you can analyze 6 video’s at the same time.
All manufacturers use it for testing. Like Porsche for their record laps.
not cheap but buy and forget.
you can see one of my last track days for updated look.
only missing ambient, oil and Pdk temps.

I’ve had this problem as well, Harry’s app on my iPhone can’t seem to get the Stsrt/Finish line right and I can never tell whether my lap times are compromised or by how much. Before I give up, I ordered an external GPS antenna with 10Hz positioning updates (vs. the phone’s 1Hz internal capacity) in the hopes that it improves the measuring accuracy.
