    I tried it a few days ago at Athens Circuit (Megara) in Greece and I was very dissapointed as it didn't work at all. Afterthat I sticked with my previous gps lap timer that works perfect for my needs.

    Well, I'd like lean angle for the bike, but now I'm being greedy. This app is pure awesome.

    Used it with my note 3 at a motorcycle track day. Placed the phone in my back protector compartment of my jacket for good satellite reception and it worked perfectly. It was just so awesome to accurately know what lap times I was doing. 5 stars!!!

    I spent a lot of money on a ir triggered lap timer. This is free and much more reliable and customisable. I've added splits to known tracks to give me even more details about my laps.

    Used with Garmin GLO or similar quality GPS receiver it's accurate, stable, invaluable tool and easy to use. Even with bike in the pit garage remains locked to sufficient number of satellites. Nice work.
