A lap timer for track days and circuit driving. Choose the track you're at, and the app handles the rest โ€” automatically detecting each lap as you cross the line. Lap Timing: Works with your iPhone's built-in GPS or a RaceBox Mini/Micro Bluetooth device for improved accuracy. Lap times are recorded automatically each time you cross the line, with sector splits so you can see where time is being gained or lost. Tracks & Sessions: Browse and manage a library of tracks. Save your favorite circuits, and build a complete history of every session you've ever driven. Your Garage: Log your sessions against specific vehicles in your garage. Whether you track different cars or motorcycles, keep your lap times organised by vehicle and watch your progress evolve over time. Race With Friends: Share your live location with friends at the track, see where they are in real time, and compete on leaderboards to find out who's quickest. The spirit of motorsport is all about friendly rivalry โ€” Lap Tracker brings that to your pocket. Built for the Track - Automatic lap detection using GPS geofencing - Support for RaceBox Mini for professional-grade accuracy - Sector split times to pinpoint where you're gaining or losing time - Session export to CSV for deeper analysis or to overlay data on a video using a tool like RaceRenderer - Follow friends' sessions live with their position on track, lap time, split and speed - Compare times with others on leaderboards Whether you're a seasoned club racer, a track day enthusiast, or just getting started, Lap Tracker gives you the data you need to drive faster.

Controlduino

Read full description

Monitor, record, chart and export combustion data in real time from your iPhone or Mac. Lambda Tuning is the official app for the Controlduino 01D21 device, featuring a wideband lambda sensor LSU 4.9, EGT sensor (exhaust gas temperature up to 1000ยฐC), and RPM measurement. Designed for professionals and enthusiasts who want to control combustion: tuning engines, burners, boilers, or any system with an air-fuel mixture. CUSTOMIZABLE APP: The app is highly configurable, whether you use a single Controlduino 01D21 device or several: choose which values to display from each connected device, customize the gauges and views, and adapt the app to your specific needs. Each device can have its own custom view based on the data you want to monitor or record. DATA VISUALIZATION: View readings in numeric format or through circular gauges and linear bars, designed for quick and intuitive reading. SIMULTANEOUS MULTI-CONNECTION: Connect from 1 to 8 units in parallel. Thanks to parallel processing, the app can receive data from up to 8 devices at 100 samples per second each, displaying, storing and charting all results simultaneously. Ideal for engines with multiple carburetors, independent cylinder banks, or systems with multiple simultaneous measurement points. LOGGING AND EXPORT: Store data sessions and export them in CSV format for further analysis. You can also chart results directly in the app and export graphs as PDF. CONTROLDUINO 01D21 DEVICE CONFIGURATION: Configure your device directly from the app: fuel selection, oxygen and RPM measurement settings, data selection for the device's display, and analog output curve adjustment. ARDUINO COMPATIBLE (OPTIONAL): The device sends data simultaneously to iPhone/Mac via Bluetooth and to Arduino boards via SPI. It includes an easy-to-use Arduino function library, with no resource consumption on the microcontroller (calculations are performed by the device itself). From the app, you can customize the device parameters (lambda, RPM, analog output...) to adapt it to your specific use case. These adjustments also affect the data Arduino receives, allowing you to obtain more accurate readings for each application. WHO THIS APP IS FOR: โ€ข Automotive professionals and enthusiasts who tune air-fuel mixture in combustion engines. โ€ข Tuning enthusiasts who need to monitor air-fuel mixture in real time to optimize engine performance. โ€ข Technicians and installers working with burners, boilers, and combustion systems. โ€ข Makers and Arduino users who want to integrate combustion sensors into their projects. IMPORTANT: To visualize and record data in real time, you need the Controlduino 01D21 device hardware. Without it, you can open binary files recorded by other users who do have the Controlduino 01D21 device, export to CSV, chart data, and save graphs as PDF. SAFETY WARNING: The lambda sensor heats up during operation. Properly installed in the exhaust system, there is no risk, but during testing do not leave it unattended on plastics or flammable materials, as it can damage them or cause a fire. In applications with running engines, burners, or boilers, exhaust gases reach very high temperatures and can be toxic. Make sure to take the necessary safety precautions.
