Measure acceleration times such as 0–60 mph, 60–120 mph and 1/4 mile directly with your iPhone — accurately and without extra hardware. The app is designed so it doesn’t need to be operated while driving; you just set everything up beforehand while stationary. Measurements then start automatically — when the target speed is reached or when a start is detected. You can save results locally on your iPhone and, if needed, export them or transfer them to other devices. Preset timers: 60 ft, 1/8 mile, 1/4 mile, 1/2 mile, 1 mile, 0 – 60 mph, 0 – 120 mph, 50 – 75 mph, 60 – 120 mph, 0 – 100 km/h, 0 – 200 km/h, 80 – 120 km/h, 100 – 200 km/h. All timers are, of course, fully adjustable. The free version measures up to two times per run. How to use the app: Check the timer settings on the start screen. If everything looks good, place your iPhone in the car where it has good GPS reception and is held securely, then start the acceleration test. You can adjust the timer configuration in the Settings screen (just tap the relevant timer). Then return to the race screen and follow the previous instruction. Optional PRO version (in-app purchase): 1. Up to four timers in parallel (instead of two) 2. Precise determination of elevation differences 3. Simulation of a Sportsman start and reaction-time measurement 4. No ad banners

Read full description

Our programming app* has undergone a major revamp to enhance the user experience, with particular attention paid to modernising the interface and simplifying the vehicle lookup. The update also introduces features that deliver essential TPMS information and the flexibility to operate offline.  Let’s take a closer look at what’s new and revisit what else the app has to offer. What’s New? Favourites Add the vehicles you program most often to the ‘Favourites’ tab and access them quicker than selecting the make and model each time. Relearn Type Discover which type of relearn procedure applies to a vehicle (auto relearn, OBD, etc.) and what the process involves.    Automatic Updates Always have the latest coverage at your fingertips. The vehicle database automatically updates when you launch the app**. Offline Usage No internet? No problem! The app runs smoothly without a connection too. In this instance, it will draw on the last database downloaded. A Reminder of What Else the App Offers Superfast Configuration Configure a Hybrid NFC sensor in one tap. It’s as quick and easy as making a contactless payment.  Zero Interference Don’t worry about disturbing other sensors whilst configuring. NFC works over ultra-short distances. Two Ways to Configure Configure a sensor by creating a new ID or entering an existing OE sensor ID. The Manual ID option enables users to skip the relearn process as the ID (in the ECU) is unchanged.  Please note, before using the vehicle lookup, you must select Europe (EU), North America (NA) or Australia (AU) to access the appropriate vehicle database for your location. *Available for the iPhone 7 or newer with a minimum of iOS 15. **Mobile data or a Wi-Fi connection is required.
