11月2日的SpeedBox Performance Tracking应用程序分析

How fast is your car, really? SpeedBox times acceleration runs like 0–60 mph or the quarter mile, automatically via GPS and with nothing but your iPhone. Tap start, drive off, done: Timing begins on its own as soon as you pull away and stops at the finish. No stopwatch, no passenger needed. You keep your full attention on driving. WHAT YOU GET • Hard numbers instead of gut feeling: real performance data for your car • Compare before and after, following a tune, new tyres or a software update • Several runs back to back without resetting anything, ideal for track days and club racing • Every result saved, with date, distance, elevation change and slope • Compete with drivers worldwide: your best times go to the Game Center leaderboards • A fraction of the price of professional GPS timing devices NEW IN VERSION 3 • New measuring screen with a large gauge, easy to read in a mount, in landscape too • Live comparison: while you drive, you see whether you're ahead of or behind your personal best • A speed curve for every run, and two runs side by side • Your route on a map • More times from every run, such as 0–30 mph or the 1/8 mile, plus acceleration in g if you want it • Video with your numbers: every run is saved to Photos as a clip with speed, time and result • Weather for every run: temperature, air pressure and density altitude • Speed and time on the Lock Screen, in the Dynamic Island and in CarPlay MEASUREMENTS • The classics: 0–60 mph, 30–70 mph, 60–100 mph, 0–100 km/h and many more • Distances: 150 m, 1/8 mile, quarter mile, 1/2 mile and 1 mile • Special modes: drag race, Rolling 50 and top speed • Choose mph or km/h • Favorites and recently used modes always at hand COMFORT • Start countdown and sound signals at the start and finish • Two designs: Track (dark, for your mount) and Classic (light) • Slope compensation: fair, comparable results even uphill or downhill • Apple Watch: status, speed, time and result at a glance, start and stop timing right from your wrist • Adapts automatically to your iPhone's light or dark appearance • VoiceOver announces the start and the result EVEN MORE PRECISE An external 10 Hz Bluetooth GPS receiver makes timing considerably more accurate.
