Devices which do not contain suitable GPS hardware may work when combined with a compatible external GPS device. Performance depends on good GPS reception conditions, and may vary. Features, capabilities, and pricing may differ between platforms and are subject to change at any time. OBD functionality is optional, and would require a supported OBD-II interface device and a compatible OBD-II compliant vehicle. See website for details. Features and capabilities can vary depending on your device and other circumstances. Use of Live Streaming feature is optional and requires a premium upgrade. Services are provided as-is, and are subject to change or discontinuation at any time. This functionality does have privacy implications. Please see this app's online documentation and http://Live.RaceRender.com before enabling its use. Use of Live Streaming service requires an Internet connection, and is therefore subject to your wireless carrier and/or Internet provider's data rates. Continued use of GPS running in the background can dramatically decrease battery life.

Speedy turns your iPhone into a drag-strip timer. Just drive. Speedy detects your launch by itself, times the run, and saves the result — no buttons to press while you're accelerating. WHAT IT MEASURES • 0–60 mph / 0–100 km/h • 0–130 mph / 0–200 km/h • 60–130 mph / 100–200 km/h • 60 ft, 1/8 mile and 1/4 mile, with trap speed • Splits every 10 mph (20 km/h) BUILT FOR ACCURACY Speedy pairs GPS with your iPhone's accelerometer to pinpoint the exact instant you launched, instead of waiting for GPS to catch up. 0–60 is reported with the 1-foot rollout used at real drag strips, so your times line up with how cars are actually tested. An honest signal indicator tells you when conditions aren't good enough to trust a run — no fake numbers. EVERY RUN KEPT • Results saved automatically on your phone • Map and speed trace for each run • Altitude, temperature and density altitude recorded alongside • Share your best times to the leaderboard YOUR UNITS mph or km/h · °F or °C · feet or metres Questions or suggestions?
