First, yes you must mount the phone on your Motorcycle! I use the Quadlock but I’m sure any will do. It won’t work correctly through your leathers.
I’ve been using this app for the past two years at NJMP Thunderbolt and I am super happy. It has been accurate and reliable. The Dashboard view gives you split times in four sectors (at least at that track, every track may be different)
You can view a graphic of an individual lap or all of them together.
I was going to buy a $400 lap timer but my wife would have killed me. $20 is the most I’ve ever paid for an app, and I’m totally happy with the purchase. If you’re in the market for a lap timer buy this and use the devise you already have. I’ve used it with and iPhone X and now with the iPhone XS.
