First and foremost, always drive safely. This app is intended for responsible use in a
motorsports environment. Only use this application's controls or display when it is safe to
do so. Mount the device securely inside the vehicle. Use at your own risk.
- GPS Signal
GPS flashing red X for more than a minute?
If so, please follow these steps:
- iPhone & iPad:
Go into your device's Settings app, select Privacy, select
Location Services, ensure that it is set to ON.
Also scroll down to TrackAddict and ensure that it is also set to ON.
Go into your device's Settings app, select "Location access" or "Location",
and ensure that it is turned on.
On some devices this will be a simple On/Off switch,
but others will have an "Access to my location" checkbox that needs to be
enabled, along with any options listed under "Location Sources".
Make sure that your device either has an internal GPS (all iPhones and
cellular-capable iPads do), or has a
supported external GPS turned on and connected.
Make sure that your device is not in Airplane Mode. This can be done in
your device's Settings app.
Follow the tips below for improving GPS reception, and allow it a minute
or two to get a good signal.
GPS reception is critical! Please make an effort to get a good signal.
Accuracy of lap times and position data is limited based on the quality of the
GPS hardware, its signal reception, and platform limitations.
Most significant lap timing inaccuracies or inconsistencies are due to the GPS
hardware having poor reception conditions.
GPS hardware may not always realize when it has a reception problem, so please
follow this advice even if it reports a "good" or "best" quality signal.
- iOS: It is recommended that you use the Reliable GPS mode
on the More Options screen. It should
not be as easily affected by tilt, vibration, or device movement. This is especially
important for motorcycles, aircraft, and watercraft.
For best results, securely mount the device (or external GPS add-on,
if applicable) in a location where it is away from metal and has an unobstructed view to
Cars & Trucks: A windshield mount is often the best location for GPS quality, camera angle,
and visibility to the driver. Try to use the front windshield, dashboard, or rear window areas;
avoid areas that are beneath the roof or other metal.
Motorcycles: Avoid placing the device in the rider's pocket. Securely and safely mount the device
to the bike. The rear cowl area may be a good location, as long as there is only plastic (no metal)
between the device and the sky.
Karts: Avoid placing the device in the driver's pocket. Securely and safely mount the device
to the kart.
Although smartphone GPS receivers tend to have limited reception and data precision, many of
them can work well for lap timing and position data, when provided with a good consistent signal.
External GPS add-on devices are also supported, and can offer much
better reception, accuracy / precision, sample rate, and mounting options.
Driving near very high track walls, large buildings, and other large obstructions have been
known to interfere with the GPS signal.
Proximity to electrical devices that cause radio interference can also have adverse effects
on GPS reception.
Please see Accuracy of GPS Data and Lap Times for
- Add-on Devices (GPS and OBD-II / CAN)
For information on external GPS devices, OBD-II / CAN sensor interfaces, and other
products, please see the interoperability page.
These are not required for iPhone users or many Android users, but are options
that can enable you to do even more with this app.
Other devices which do not have an internal GPS receiver will require a compatible GPS
In rare cases, it may be useful to reboot your smartphone or tablet, or to fully terminate
and restart the app, if it is unable to connect or reconnect to a Bluetooth add-on device.
- Video (excluding External Camera Control)
If recording video, always position the device in a "Landscape" orientation. This is when you
rotate it onto its side, so that it is wider rather than taller. "Portrait" orientations
have undesirable image proportions, and are not supported for video recording.
You will need to give this app access to your device's camera (on iOS 8) and microphone (iOS 7 & 8).
If you had mistakenly declined this access, please follow these steps:
iOS 7 and newer: Go into your device's Settings app, select Privacy, select Microphone, then scroll down to TrackAddict
and ensure that it is also set to ON.
iOS 8 and newer: Go into your device's Settings app, select Privacy, select Camera, then scroll down to TrackAddict
and ensure that it is also set to ON.
- Video takes quite a bit of space, especially when recorded at high resolutions. If your video stops
recording short, which may be followed by the data stopping short as well, then your device is most likely
out of storage space. There is a time indicator on the left side of the Setup
screen, under the "Video:" label, which estimates the amount of recording time
available at the current video setting. However, the system wont let apps use up 100% of the reported
available space, so this is only an estimate, with an assumed amount of non-usable free space. Other
factors can skew this estimate as well, so it's best to make sure that it shows more recording time than
you really need.
Video recording will terminate if the app is placed in the background. See the section further below regarding
- Video/Data Overlays and Export Options
This app offers the convenience and simplicity of creating videos with data overlays right on
your device, but you can also
copy the raw data and video to your computer for high-quality
overlays with far more options and control in
Rendering videos from within the app will require extra storage space, and data overlays will take
more time to process. It is recommended that you limit the number of laps selected on the
Session Data screen when you export a video. If nothing
is selected, it will export nearly the entire session.
The raw video and data files can be easily transferred to another device running this app, or to
by using WiFi Transfer.
- You can also copy the files to your computer by using
USB File Transfer.
Another option is to export the data via E-Mail.
- Background Operation
This app will have limited capabilities and performance when placed in the background. This is due to
technical and system restrictions that are beyond our control.
It is automatically placed in the background when you press the device's Home or Power/Sleep buttons,
receive a call, or enter another app. You may be able to simply dismiss some incoming notifications
(such as texts) without causing the app to enter background mode, however any incoming call may still be
In general, it is not recommended to record a session while it is running in the background.
The capability to automatically continue recording when placed in the background is only intended for short
durations, and may still experience problems and/or limitations, depending on the device and conditions.
Due to platform limitations, video functionality is not supported in the background. This affects video
recording, as well as rendering / exporting.
If the app enters the background, the video recording or processing task will likely be terminated.
Communications may be blocked or otherwise impacted after entering the background, depending on the device
and conditions. This can potentially interfere with Live Telemetry Streaming, OBD and GPS device connections,
and WiFi transfers.
The app may be automatically suspended or terminated by the system after it has been running in the background
for a period of time.
- Other Tips
To obtain good accelerometer data (G's), firmly mount the device as straight or flat as possible in
the vehicle. If it is mounted at an angle, or exposed to movement within the vehicle, this will reduce
the accuracy of the G-force data. If it is mounted upright, the app will attempt to compensate for the
pitch or roll angle, but any left/right yaw will increase the amount of error in the readings, and cannot
be easily compensated for. Although the center of the vehicle can be a good mounting location for
collecting G-force data, it is often poor for GPS signal quality, so this mounting location is not
When using Segment or Drag Race mode, excessive
vibrations may trigger the accelerometers to start the timer. There is a minimum threshold that is
intended to prevent this from being a problem in most cases, but if your engine shakes the Earth, it's
possible that it may trigger this. You should be able to mitigate this by cushioning the device or
otherwise limiting the vibration it is exposed to. Mounting the device at an angle (up to 45 degrees)
can effectively raise the threshold needed to trigger the timer. That may compromise the recorded
G-Force data, but it probably has a fair amount of error in it if you get that much vibration anyway.
Have your battery well charged before use. This app is capable of using the internal GPS, accelerometers,
high-definition video recording, and network & Bluetooth communication, all at the same time
(depending on your settings). Not surprisingly, this will consume the battery charge faster than a simpler
app. You may get better battery life by using the More Options
screen to disable any OBD or Bluetooth modes that you aren't using, turn off Live Streaming if you don't
need it, turn off External Camera Control, and set the GPS option to Reliable.
Your device may get warm during recording, and in some cases, overheat and trigger the safety
shutdown. This is unfortunately a possibility for this type of app, which is not limited to
this specific product, and may vary depending on the device you are using. It is typically
caused by a combination of the internal GPS, accelerometers, and video system being active, which
can then be compounded if the device is mounted in a position that is exposed to direct sunlight
and/or high temperatures. If you can shade the device with a non-metallic material (to avoid
diminishing GPS reception), that could be a good idea. Be sure to use the
screens to turn off options that you aren't interested in using, which may reduce the heat generated,
as well as lower the battery consumption.
If you have an iPad® or Android™ tablet, its larger screen may be desirable
for video playback, analysis, OBD-II monitor, etc. You can easily copy session data and video to it via
WiFi Transfer. It is generally not recommended to use a full-size
tablet for session recording, because of the difficulty of mounting it securely in a good location, but it
is possible to use. That would require an tablet equipped with internal GPS chip (3G / 4G / LTE iPad models)
or a compatible GPS add-on device.
