Can’t update old version – G Play doesn’t show “update” button while I definately see that my version currently installed is old one.
July 24th, 2012 at 16:48
SOLVED! Installed new version by downloading .apk file from your site. Had to turn on external sources…
For some reason app is not shown in the list when i open “My apps” in GPlay. Anyway – works fine now, Thanks!

“Added expert setting “Do not modify GPS” to disable modification of MTK chipset settings”
When, where and why useful this settings?
September 16th, 2012 at 13:37
gtommi: Only if you’re modifying GPS settings manually and don’t want RaceChrono to override them
September 16th, 2012 at 23:52
Is there any ETA for OBD?

Hello Antti,
I got problems whit a chinese android device, it seems that cannot see the GPS (qstarz 810) with the racechrono app, with other GPS log apps it works!
Pls help me for this issue!
Thanks

I forgot to say that on my Chinese android device is installed Android 2.3.4 version.
Thanks

update, I tried the same 2.11 version on an HTC Wildfire with Android 2.2 and also with this device was impossible to connect the external GPS, is it a bug?
Thanks

Excellent, this was actually the only reason why I kept my WM6 phone and while there were similar apps for android, it is still second to none.
One single complain would be the lack of performance tests which were available in the old version. Is it planned to include it?
Other question is whether there is a way to donate the development?
Thanks

Kawlman: Performance testing is quite common request, and I do plan to include it once I’m happy with the lap timing features. You can donate at http://www.racechrono.com/download/ (see the donate button at the top).

MyRaceChrono sign-in is Bigfla. I use a Samsung Galaxy S2. Questions for you, please.
1. Does your pdf manual apply to the Android version?
2. How do I get to MyRaceChrono?
3. Is there a video mode (like Trackmaster or Harry’s Lap Timer for the iPhone)?4. How do I use racechrono2avi to make overlays on videos (eg from Trackmaster)?
By the way, I prefer the look and feel of RaceChrono to Trackmaster.
Thanks
