Settings

To change settings of the app, touch the [Settings] button or select G-Bowl in the Settings screen of the iPhone.



GENERAL
Drivers #1 ~ #5 Presets the driver name which will be recorded in a drive log.
Auto-Pause Suspends the recording of the drive log when the car stops, for example, at a stop light. Recording is automatically resumed when the car starts again.
Auto-Stop Automatically stops recording when the set time has passed after starting G-Bowl App to prevent excessive battery consumption in case the app is not stopped.
Auto-Stop Time Sets the time for auto-stop.
When the log is opened Set whether the initial position when displaying the running log should be the top or the end.
Screen Orientation For iPad: Select automatic or fixed landscape orientation (used when the landscape orientation cannot be fixed due to the OS version of the iPad).
SOUNDS AND ALARM
G Limit Alarm This function alerts the driver with an audible warning when the G-force exceeds the value set in [G Limit] while driving.
In consideration of vibrations inside the car, momentary overshoots are allowed, and warnings are given when they are clearly exceeded.
G Limit Sets the limit of G-force (0.2 ~ 1.2 G).
Braking Diagnosis
Judges the driver’s braking operation to stop the car. A honk sound is set off if the braking is judged good, and a bell sound if judged bad (additional braking during slowing down is judged bad). No sound is set off if the braking cannot be judged either good or bad.
Diag – Report on Sets if the result of braking diagnosis is reported “only if it is good” or “both when good and bad.”
Jerk Limit Alarm A notification sound is emitted when the jerk generated during driving exceeds the value set in [Jerk Limit].
Jerk Limit Set the upper limit of jerk to be used in [Jerk Limit Alarm].
Snap Limit Alarm A notification sound is emitted when the snap(= differentiate jerk) generated during driving exceeds the value set in [Snap Limit].
Snap Limit Set the upper limit of snap to be used in [Snap Limit Alarm].
Snap Limit – Noise Reduction Reduce false notifications due to vibration in [Snap Limit Alarm].
G SOUND
Sound for G-Force Turns on/off the function of producing tones of different pitches depending on the G-force on the car. This allows the driver to know the changes of G-force without looking at the screen during driving.
G Volume Slider Specifies the volume of the G sound.
Note: This is a sub volume for the G sound only. Even if you maximize this volume, you will not hear the G sound if the iPhone volume is low or the silent switch is on. 
G Sound Mode Selects either “Tone Scale” or “Sweeping Sound” for the G sound.
Base Tone Specifies the base tone for G sound (= 0 G). The pitch of G sound increases as G-force increases. The default is the tone of sol.
Tone Intervals (/G) Sets the number of tone intervals in 1 G (10 ~ 40 intervals). The default is 30 intervals. If the tone scale starts with sol, a change of 0.1 G is expressed in terms of 3 tone intervals: “♪la♪ti♪do.”
Mute Threshold Sets the lower limit of G-force below which G sound is muted. Specify this if G sound is annoying when the car is standstill or under steady driving.
Prefer Score Reading Mutes G sound when a score is read aloud for a better hearing of the score.
SCORING SYSTEM
Display Score The objective is to control G-force throughout cornering, maintaining G-force as close as the “Target G.” The driver’s performance is evaluated on braking (deceleration) G (max 5 pts), cornering G (max 3 pts) and acceleration G (max 2 pts), totaling 10 points at the maximum. The obtained score is recorded in the drive log. Note: This function measures only the driver’s G control ability throughout cornering and does not consider elements (such as the driving line) other than G-force. Thus, a high score does not simply mean “a good cornering.”
Target G Sets the desirable value of G-force for scoring. The recommended values are 0.2 ~ 0.3 G on city roads and 0.3 G or more on winding roads depending on the car speed.
Scoring Mode The default is “Braking + Cornering + Accel.” If “Cornering Only” is selected, braking G-force and acceleration G-force are not considered and cornering (lateral) G-force is evaluated on a scale of 10 points.
G MEASUREMENT
Record Z-Axis G Record G in the vertical (Z-axis) direction in the log.
Road Noise Filter G-Bowl App measures, with the G sensor, G-force on the car 20 times a second and obtains G data after noise reduction processing. Sets the strength of noise reduction processing (Auto/Weak/Medium/Strong). “Strong” makes the G graph smoother but reduces the response of measurement. Note: “Auto” is recommended when the scoring system is used.
LOCATION MEASUREMENT
Map Scale Sets the initial scale of the map displayed on the log display screen.
Map Type Selects the default display type of the map from “Map,” “Satellite” and “Map + Satellite.”
G METER
Starting G Sets the minimum G-force (starting position of the needle) for G Meter response.Sets the minimum G-force (starting position of the needle) for G Meter response.Peak Hold Turns on/off the peak hold display of the G meter.
Peak Hold Turns on/off the peak hold display of the G meter.
Peak Hold Time Sets the duration of peak hold in seconds.
G-BOWL
Display Track Turns on/off the track of the ball displayed on the image of G-Bowl. (Turning on/off the track can also be done by touching G-Bowl during operation.)
Track Dot Interval Specifies the dot interval of the track in second (1/2 sec ~ 1/16 sec). Since 32 dots are displayed in all, a track in 8 seconds will be displayed if this is set for 1/4 second.
Smooth Motion Turns on/off the smooth animation display of the ball and track. It is recommended to turn this off on low-performance devices such as iPod Touch 4 and iPhone 4.
Display G Peak The peak point of the ball’s trajectory is indicated by a red dot.
Max number of display Set the maximum number of G peaks to be displayed simultaneously (10 to 300).
Hight of G Peak Specify the height of G to judge as a peak.
Ignore G Peak Do not display G peaks less than specified G.
G GRAPH
Graph Mode Select the graph display mode.
Bold Line The graph line is displayed thickly.
Display Z-Axis G Turning this on displays vertical G (Z-Axis) in a white graph. 
Display Yaw Rate Turning this on displays the yaw rate in a purple graph.
Yaw Rate Scale Selects a scale range of the yaw rate graph from 0.2 ~ 3.0 rad/s. (The scale range can also be changed by swiping the graph screen up or down with two fingers.)
Display Speed Turning this on displays the speed of the car in a yellow graph.
Speed Scale Selects a scale range of the speed graph.
Display Jerk Turning this on displayes the Jerk graph.
Jerk Scale for G Select the display ratio of Jerk graph to G graph.
Differentiate Jerk Turning this on displayes the snap(differentiate Jerk) graph.
Differential of Jerk Scale for G Select the display ratio of Snap graph to G graph.
Update Frequency Specifies the frequency of graph updating during driving (1/sec ~ 10/sec). Lower frequencies reduce battery consumption. (This setting does not affect the log recording frequency.)
Horizontal Range Specifies the default value of the horizontal (time) range of the graphs (2 ~ 600 sec). (The range can also be changed by pinching the graph during operation.)
Vertical Range Specifies the default value of the vertical (G) range of the G graph(s) (0.4 ~ 5.0 G). (The range can also be changed by dragging the graph up or down during operation.)
Rotation Mode If iPhone is rotated while displaying the log screen, the graph is enlarged to the full screen. This setting specifies the mode of enlargement.
Min G for Plotting Specifies the minimum G-force (0.00 ~ 0.10 G) for plotting a graph. This is used to avoid plotting noises near 0 G.
Fill Lateral G In graph mode ‘(5) Lateral G’, the lateral G graph displayed as a filled graph not line graph.
Draw Accel as Plus In graph mode ‘(6) Accel&Brake G’, graphs with acceleration in the positive direction and deceleration in the negative direction.
Graph Colors 1 Specifies the graph colors of braking G and acceleration G. The default is red for braking and blue for acceleration, and the colors can be interchanged.
Graph Colors 2 Specifies the graph colors of yawrate and Jerk. The default is purple for yawrate and cyan for Jerk, and the colors can be interchanged.
Log Background Color Sets the background color (black/white) of the log display screen. Black is the default and white is mainly for printing the screen.
Display Raw Data Displays raw measured G data over the graphs. This allows you to see raw data before noise reduction, which is performed by setting “G Measurement” – “Road Noise Filter.”
RESET
Reset Guidance The guidance message is displayed only once after starting the application. Reset the guidance message to see it again.
Reset All Resets all settings, including calibrations. (The saved logs are not deleted by this resetting.)
