Introduction to Temperature
The Temperature app is a modern solution for one of the most overlooked issues in today’s vehicles — the absence of a built-in temperature gauge. As automotive technology advances, many car manufacturers have chosen to remove traditional dashboard temperature indicators from base models to cut costs. Unfortunately, this leaves drivers unaware of critical engine temperature changes until it’s too late.
That’s where Temperature comes in. Developed by Hakim Nouri, this simple yet intelligent application turns your Android smartphone into a professional-grade vehicle monitoring system. By connecting your phone to an OBD2 ELM327 device, you can instantly view your engine’s temperature and battery voltage in real time.
The Temperature app not only enhances your driving safety but also extends your engine’s lifespan by keeping you informed and in control.

The Temperature app is lightweight, easy to install, and designed for seamless integration with Bluetooth-enabled OBD2 devices. It’s the perfect tool for drivers who want real-time feedback on their engine’s condition.
Why Temperature Matters
The temperature of your engine is one of the most crucial factors that affect its performance and longevity. An overheated engine can lead to severe damage — warped cylinders, broken gaskets, or even total engine failure. Unfortunately, many drivers remain unaware of these dangers until their check-engine light appears, often when it’s already too late.
The Temperature app solves this problem by providing a real-time temperature reading that lets you monitor your engine’s heat level while driving. With this app, you can spot unusual temperature spikes instantly, take preventive action, and avoid costly repairs.
Key Features of Temperature
1. Real-Time Engine Temperature Display The app delivers accurate, live data from your car’s ECU (Engine Control Unit), showing your engine’s temperature in Celsius. You can easily read the current temperature — for example, 63°C — through the app’s clean and easy-to-understand interface.
2. Battery Voltage Monitoring In addition to temperature, the app also displays your battery voltage (such as 14.0V). This ensures your vehicle’s electrical system is functioning properly, giving you an early warning if your alternator or battery starts to fail.
3. Bluetooth Connectivity The Temperature app connects wirelessly to your OBD2 ELM327 device through Bluetooth, eliminating the need for cables. Once paired, it automatically recognizes your device each time you open the app.
4. Simple, Elegant Interface The app features a beautiful, minimal design that prioritizes clarity and usability. Large, bold numbers make it easy to monitor your temperature and voltage at a glance, even while driving.
5. Free and Secure Installation Completely free to use, the Temperature app is verified by Google Play Protect, ensuring a safe installation and operation process on your device.
6. Offline Functionality Once paired with your OBD2 device, the app functions entirely offline — perfect for long drives in areas without mobile coverage.
Important Requirement: OBD2 ELM327 Device
Before using Temperature, you’ll need a compatible OBD2 ELM327 Bluetooth device. This small plug connects to your car’s diagnostic port (usually located under the dashboard) and communicates directly with your smartphone.
The device serves as a bridge between your vehicle’s onboard computer and the Temperature app, allowing you to read accurate temperature and voltage data in real time.
Step-by-Step Guide to Using Temperature
Step 1: Download the App Start by downloading Temperature on your Android device. It’s 100% safe, verified, and free.
Step 2: Install the App Allow installation from external sources if prompted. The app will be scanned automatically by Google Play Protect for security assurance.
Step 3: Connect the OBD2 Device Insert your OBD2 ELM327 adapter into your car’s diagnostic port. This port is typically found under the dashboard, near the steering column. Once plugged in, turn on your vehicle’s ignition.
Step 4: Pair via Bluetooth Open your phone’s Bluetooth settings and search for your OBD2 device (usually named “OBDII” or “ELM327”). Pair it to your smartphone.
Step 5: Launch and Connect Open the Temperature app. Tap the blue connection button to select your OBD2 device. When the green Bluetooth icon appears, your connection is successful.
Step 6: Monitor in Real Time Once connected, the app will begin displaying your engine temperature and battery voltage. Keep the app running while driving to continuously monitor your vehicle’s health.
Benefits of Using Temperature
