I took advantage of the 3 session trial. My first session seems to have worked great. The times appear to match my GoPro videos very closely. The second session didn't record any of my laps. I started and stopped the timer and ended up with no laps. The GPS was all over the place in the third session. I don't know what to blame here because a bad GPS reading can come from so many variables. Overall., when this app works, it's an awesome, cheap track tool. I plan to buy the lap timer feature next season.
Uodates December 2016: App just miserably failed me at the track. 5 sessions and all do not have video... Thanks a lot ... App was great and than seems abandoned. Just does not work at all any more... Still waiting on response from the previous issue. Update from June 2016 update on my 5 star review .This thing has ate 4.5 GB of mobile data in 2 2 minute sessions while recording. What's up with that? The only available sync is over Wi-Fi and why is it using mobile data while recording? Until answered or fixed rating will remain as is.
Doesn't work well for point to point courses After entering start and finish lines, the app was not able to find them more than half the time. There is no user manual, it goes to FAQ's. Tried contacting tech support. They responded 6 days later with a canned answer that didn't apply to my question.
Nothing works GoPro integration, broke. Website upload, broke. Lap timer, 1 of three sessions actually count. Asked the dev for help with the GoPro integration and got a canned response that had nothing to do with the question. Can't believe I spent $15 on this. Don't be a sucker like me.
I don't go to the track without it! Hands down the easiest to use. I use it with an external GPS for my tests and club races and it's awesome. Lap times are near identical to the official times and now they have an analytics app that brings all the basics and best from AIM Race Studio Analysis but with just the app. Love it!
Several bug fixes and performance enhancements.
The friendliest lap timer, data / video recorder, and analysis app available.
