Read full descriptionHide full description
デジスパイス社製のGPSロガー”デジスパイス3、4”と連携し、ドリフト走行している車両の情報(時刻、位置、速度、車両姿勢など)を記録するアプリです。対応製品をご購入の上ご使用ください。 Bluetooth Low Energy(BLE)経由のデジスパイス測位情報とiOS端末のモーションセンサー値とを記録します。記録したデータをもとにパソコンのデジスパイス解析ソフトを用いてドリフト走行をアニメーション再生することができます。走行速度やドリフトアングルをグラフや数値で見ることができます。 このアプリで記録したデータを表示するには、デジスパイス解析ソフト Version 4.0.0 以降が必要です。 公道では決してドリフト走行を行わないでください。管理された場所で安全のための措置をとったうえで行なってください。 GPS受信状態によっては正しい情報が記録できない場合があります。上空が開けた場所で走行してください。 走行開始から停止まので間に1秒程度の直進走行が含まれていなければドリフトを検出することができません。走行には必ず直進走行を含めてください。 記録したデータはパソコンiTunesのファイル共有機能を用いて取り出すか、アプリからメール送信します。
QUAD
This app uses your phone's sensors and GPS to provide real-time lap timing, sector splits, and vehicle dynamics data like G-forces and four-wheel weight transfer. It also includes a data logger for post-drive analysis and alerts for understeer and oversteer.
- GPS lap and sector timing
- Four-wheel load monitoring
- Real-time G-G diagram
- Understeer/oversteer alerts
- Data logging and playback
- Customizable UI themes and units

A GPS lap timer that works anywhere on Earth, and an integrated vehicle-dynamics G-force meter. Using nothing but your phone's sensors and GPS, it times laps and sectors while showing four-wheel weight transfer, G-forces and chassis attitude in real time. No extra sensors. ■ GPS lap timer Circuits, of course — but you can set a course anywhere in the world. Long-press the map to place start, finish and sector lines, and every crossing splits a lap and a sector automatically. Best lap, last lap and every sector time stay on the main screen, so you can see where you are finding time while you drive. Closed circuits and open point-to-point courses are both supported, so rally and hill-climb stages work too. Save as many courses as you like, set which direction counts as a crossing, and add as many sectors as you need. With no course set, the LAP button still times from where you stand. ■ One integrated meter Four-wheel load, the G-G diagram, yaw rate and roll/pitch on a single screen, right alongside the lap display. Everything you need while driving, in one place. ■ Four-wheel load monitoring Weight transfer is computed from G-forces and your vehicle specs, then shown at each corner as colour and numbers, so you can see whether you are using all of the tyre. Load falling shifts blue, load building shifts red. Delta/absolute and %/kgf are both switchable. ■ G-G diagram Lateral against longitudinal G, with the trail you actually drove and the envelope of the limit you reached. The envelope is where your car's grip runs out, drawn for you. ■ Understeer and oversteer alerts Measured yaw rate is compared against the theoretical neutral-steer reference to catch sharp yaw-rate changes in the transient, and the app calls them out by voice and colour. The axle that is losing cornering force is boxed, so you can tell instantly which end is going. Tune it with a scene (circuit / winding road) × sensitivity profile. ■ Data logger and viewer Record a session and review times, racing line and vehicle data afterwards. A track map coloured by speed, time-series charts of G, yaw rate and attitude, and the G-G diagram all follow one playhead. Understeer and oversteer segments are marked on the charts. Export to CSV to analyse the data in external tools. ■ Customisation Theme (dark / light) and accent colour, which channels appear in the readout column, the range of each meter, load display units, render rate and more. ■ Three steps to start 1. Enter your vehicle info (weight, CG height, wheelbase, track, weight distribution). It works on the defaults, but the more accurate you are, the closer the load readout gets to your real car. 2. Mount the phone rigidly, screen upright. 3. Run calibration once before you drive. No sensors handy? Settings has a "Play demo" mode that replays real recorded track data through every feature. ■ About the in-app purchase Lap timing, the data logger and viewer, understeer/oversteer alerts and UI customisation are Premium features, unlocked with a single payment. There is no subscription and nothing auto-renews. ■ Please read This app is a simulated monitor that estimates and displays vehicle attitude, load, G-forces and understeer/oversteer tendency from phone sensors and GPS. It is not a certified measuring instrument or a safety device. All values shown are approximate and are not guaranteed to be accurate real-world measurements. Load is not a load-cell reading; it is a computed estimate. Timing accuracy depends on your device's. This app is intended for competition use in closed environments such as race circuits. Watching the screen while driving is distracted driving and is illegal and punishable under applicable traffic laws. Never watch the screen while driving on public roads. If you use it on public roads you must comply with all applicable laws and do so entirely at your own risk.

Verdict
The clearest difference is update cadence: QUAD at every 2 weeks against DigSpice DRIFT's every 28 months. DigSpice DRIFT's advantage is iOS requirement (10.3 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.
