G vs GTrace

The G-Bowl is a training tool that allows anyone to improve their driving skills by driving without dropping the ball. The real G-Bowl made of resin was released in Japan in 2009 and is still widely used for driver education by automobile manufacturers, bus companies, cab companies, and others. G-Bowl Basic is an app version of this real G-Bowl, and we hope that many drivers will use it. How to use 1. Park in a place that is as level as possible.
2. Place your smartphone in the car (you can also stand it on a holder, etc.).
3. Launch this app (the level will be set automatically).
4. Start driving. A warning sound will sound when the ball falls out of the bowl while driving. The goal is to drive from your house to your destination without dropping the ball even once. When you are able to do that, your passengers will feel comfortable and safe. There are three types of balls: oil-filled balls, yarn balls, and ping pong balls. The oiled ball, which is the hardest to drop, is the default. Function - A warning sound alerts the user when the ball falls.
- Five types of warning sounds can be selected. - Touching a ball changes the ball type. - The level button (wave icon) re-sets the level at any time. - Pinch to zoom, drag to adjust position. - Lock button (lock icon) to lock the layout. - Camera button toggles camera mode (Auto or Top-down). - The phone can be placed vertically or horizontally. Hint You will find that in order not to drop the ball, you must not only drive by feeling the G's, but you must pay attention to your surroundings, drive predictably, and maintain a safe distance from your car. By the time you feel confident that you can drive anywhere without dropping the ball, your driving will have changed to something great.

Track day or mountain road, every G you used stays on record. GTrace turns your iPhone into a real G-meter. It draws the lateral and longitudinal G-forces from your cornering, braking and throttle as a live trace, then lets you replay the run against the map, your footage or the graphs. One-time purchase. No subscription, no in-app purchases. WHILE YOU DRIVE - Live G-G diagram, lateral and longitudinal G shown together - Trailing trace, with peak lateral and longitudinal G held on screen - Jerk shown as a crosshair, so you can see how smoothly you transfer load - Speed readout, switchable between km/h and mph - Audible alert when you exceed your chosen G threshold - Comfort and Sport modes with separate display ranges for street and track - Three display layouts: standard, info + speed, and video preview - Phone holder mode, so a vertically mounted phone still reads longitudinal G correctly MEASUREMENT - Gravity component removed to isolate true vehicle acceleration - 2nd-order Butterworth IIR low-pass filter with adjustable cutoff frequency - Configurable sampling rate - Axis inversion, so mounting orientation doesn't matter AFTER THE RUN - G-G heat map showing which part of the friction circle you actually used, so you can see the balance between cornering, braking and acceleration at a glance - Synced playback: G-G + map, G-G + video, G-G + acceleration graph, or map + graph, at adjustable playback speed - Time-series graphs for longitudinal G, lateral G, longitudinal jerk, lateral jerk and speed - GPS trace drawn on a map, with top and average speed RECORD AND SHARE - Voice recording, synced to the acceleration data for commentary and notes - Video recording with audio, played back with the G-G trace overlaid - CSV export for spreadsheets or your own analysis tools - Native binary format (.ggx) import and export, for backups and moving data between devices WHO IT'S FOR - Track day, sports driving and time attack enthusiasts - Drivers working on their technique on mountain roads - Anyone chasing smoother, more passenger-friendly load transfer - Motorsport competitors who want their practice data kept - Anyone who wants their car's behaviour in numbers English and Japanese. iPhone only, iOS 15.6 or later.
