Okay look, it's true that this is the best lap timer app for Android. One of my instructors used the interface to help guide me, and ever since then I've been hooked. So why 3 stars? For whatever reason the dev simply won't implement automatic video recording when starting the session. So every time you start recording before you go out on track, you have to swipe left and hit the video record button. You WILL forget, no matter how used to it you get, and it'll probably be on a best lap

I created my own data logger hardware including GPS and ECU data feeds, I linked my Go Pro Hero 8 and got video feeds. The app is quite customizable and initially you are going to work through the best setup and learning how to do the video side of things. Once you are past that learning phase it gets a lot easier and its a turn on, connect your camera and go which is great. I'm more technical and part of the fun for me was making my own hardware and configuring it - that side of things is not for everyone - I loved it.

Easy to use and we can share all our data with one another. If you forget to set your traps, you just hit start, and go in retroactively and set them. I use with my Racebox Mini, and Vbox Sport with great results.
