Simple GPS Dashboard vs OBD Diagnostics

As its name says, this app represents a very simple dashboard with the most important information about location parameters your mobile device can provide. Although the application tries to show the most accurate data according to different situations - like correcting compass heading due to device rotation - please note that results still depend on your device's hardware and software capabilities and compass calibration. Readings highly depend on built-in hardware sensors and you could experience deviations (such as expected 10-20 degrees between GPS and magnetic heading). When you are in closed spaces such as buildings or tunnels, your GPS data like speed and location can only be retrieved from networking services and cannot be guaranteed as accurate. The purpose of the application is to show the most important location and orientation parameters as precisely as possible and in the most noticeable visual form. To keep things simple, there are two modes of information display - day and night. Switch between those using the button in the upper right corner. Change speed and altitude measuring units by just tapping the value on the dashboard. You can toggle between km/h, mp/h, and knots for speed, and meters and feet for altitude. Please note that this application could use your battery intensively to keep you up with information about location, speed, and other parameters. Turn off your device screen or quit the application to save energy when information is no longer needed. All settings are always remembered.

OBD Diagnostics turns your iPhone into a powerful real-time vehicle data scanner, dashboard, session recorder, and AI analysis tool. Connect to supported Bluetooth OBD-II adapters, including Veepeak and compatible ELM327-style adapters, to read live vehicle data directly from your car. View key engine metrics, track driving sessions, graph sensor data, and send your recorded measurements to AI for personalized analysis based on your vehicle’s make, model, year, and engine. Whether you are troubleshooting a check engine light, monitoring engine performance, reviewing fuel trims, checking battery voltage, or learning how your vehicle behaves over time, OBD Diagnostics helps make your car’s data easier to understand. **Real-Time OBD-II Dashboard** Monitor live data from your vehicle with a clean, easy-to-read dashboard. View supported OBD-II PIDs such as: Engine RPM Vehicle speed Coolant temperature Battery voltage Engine load Short-term fuel trim Long-term fuel trim Oxygen sensor readings Fuel level Additional supported sensor values Large gauges, live value cards, and quick-access charts help you focus on the vehicle data that matters most. CarPlay support with live data. Shortcut actions to automatically connect and start as well as disconnect and stop analysis. **Interactive Graphs** Visualize your vehicle’s live data with real-time graphs. Select up to 10 dashboard PIDs and track changing values over the last 60 seconds. Great for reviewing RPM changes, coolant temperature rise, fuel trim movement, voltage behavior, speed changes, oxygen sensor activity, and engine load patterns. **Session Recording and History** Record OBD-II sessions and review them later. Each session can include duration, sample count, vehicle information, VIN when available, make, model, year, engine, battery voltage, and min/max/average stats for recorded metrics. Use session history to compare drives, spot changing patterns, and better understand intermittent vehicle issues. **AI Vehicle Analysis** Send recorded session logs to AI for a plain-language review of your vehicle data. OBD Diagnostics can analyze readings using your vehicle’s make, model, year, and engine to help explain performance trends and possible areas to watch. AI analysis can help summarize coolant temperature, RPM, speed, battery voltage, oxygen sensor readings, engine load, fuel trims, and other supported metrics. Choose from multiple AI provider options, including Apple on-device AI where available, OpenAI, Gemini, Claude, xAI, or a custom URL. AI Analysis should NOT be considered a replacement to a professional automotive expert. Please use the data as a means to provide a rudimentory analysis of your vehicle. **Demo Mode** Explore the app without an adapter using Demo Mode. Simulate vehicle data, view dashboards, test graphs, record sessions, and preview AI analysis workflows before connecting to a real car. **Built for Drivers and DIY Mechanics** OBD Diagnostics is useful for car owners, DIY mechanics, used car shoppers, fleet users, and anyone who wants better visibility into vehicle health and performance. **Key Features** Real-time OBD-II Bluetooth data Veepeak and ELM327-style adapter support Live RPM and speed gauges Custom dashboard PID selection Interactive vehicle graphs Session recording and history Vehicle info and VIN capture when available Min, max, and average metric summaries AI-powered session analysis On-device AI option where supported Custom AI provider support Demo Mode for offline testing Clean dark-mode iPhone interface OBD Diagnostics combines live OBD-II data, Bluetooth scanner support, real-time charts, session tracking, and AI-powered vehicle analysis into one simple app for understanding your car’s performance and health.
