12月4日 的 Drag Racing Timing: DragRacing 應用程式分析

DragRacing is an app that measures times in a drag racing machine on road without measurement facilities. The app measures times with GPS at 60 feet, 330 feet, 660 feet, 1000 feet, 1/4 mile and 1/2 mile. It is a very useful app for test run or training of drag racing! Please use it with safety first. Please comply with the law when using it on public roads. (How to use) 1. Fix the iPhone (or iPad with GPS) with DragRacing installed on the dashboard of your car so that it does not sway. If your iPhone doesn't fall while accelerating, you can just put it on the dashboard or center console. 2. Tap the Start button (or Start / Repeat button). If the car is stopping, “In Prep" is displayed, and if the car is moving or the device isn’t capturing GPS signal, "Waiting for Stop" is displayed. (If the device isn’t capturing GPS signal, "GPS" mark to the left of the DragRacing logo shows in thin gray.) 3. When the car stops and the message “Start at your timing / Ready" is displayed and an audible alarm will sound at the same time. Then start your car at your own timing. When your car starts, measurement starts and "Measurement Started" is displayed and the timer will begin. The screen frame turns green during measurement. 4. If your car decelerate during measurement, the measurement will finish and "Finished" will be displayed. 5. If the "Start/Repeat" button was tapped, when the speed drops near a stop, "Waiting for Stop" is displayed to prepare for the next measurement. You can end the measurement by tapping the "Stop" button. 6. When the measurement is finished, the latest result will be displayed. To see past results, tap the "Result" button (or the "▼Newer" button) and then use the "▼Older" and "▼Newer" buttons. (Button function) - Stop: The measurement will end immediately. - Start: Makes the measurement only once. - Start/Repeat: Repeats the measurement. It is convenient for repeated measurement in urban areas where there are many signals. - Share: A window opens to share the displayed result. - ▲Newer: If the date of the currently displayed result is not displayed, it will be displayed and the Results button will change to the ▼Older button. If the date is displayed, the past results displayed with the ▼Older button will be reverted to new results. - Results: The date of the currently displayed result is displayed and the button will change to the ▼Older button. - ▼Older: Displays older results. - km/h / mph: Selects the unit of speed (Measurement item) - Timing at 60 feet and 330 feet - Timing and speed at 660 feet, 1000 feet, 1/4 mile and 1/2 mile - Timing at 60 mph and 100 km/h - Max speed (Large speed display on the screen) You can turn it on and off by tapping the Stop button twice in the stopping state (when neither the Start button nor the Start / Repeat button is tapped). (Sensitivity setting of start sensing) In the stopping state, tap buttons “Stop → ▲Newer → ▼Older → ▲Newer → ▲Newer" to open the setting window at the top of the screen. You can select 5 levels of sensitivity. Adjust if there are many false start sensing or if the response is slow. Probably no adjustment is necessary. (Note) - 1000 cases of measurement history are stored. - When you uninstall and reinstall DragRacing, the stored measurement history will be deleted. - Dark mode compatible. - No advertisement in the app. - The app does not work on iPads without GPS. - If the GPS signal is weak, the operation may become unstable. - The developer assumes no responsibility for any accident, violation, loss or claims by third parties which may arise from the use of this app. Terms of Use: This application is provided under the Apple Standard End User License Agreement (EULA). https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
