DashCommand Review: An Excellent OBD2 App for Car Diagnostics in 2025 Overview
DashCommand is a premium mobile application developed by Palmer Performance Engineering, the same team behind the renowned ScanXL professional software. It’s designed to work with a wide variety of ELM327-compatible OBD2 Bluetooth or Wi-Fi adapters, acting as the brain that interprets and displays the data from your vehicle’s network. Its main purpose is to provide real-time monitoring, advanced diagnostics, trip logging, and performance measurement, all through a highly customizable interface that you can tailor to your specific needs and vehicle.
This product is designed for car owners who want more than just a code reader. The target audience includes DIY mechanics, performance enthusiasts, hypermilers tracking fuel efficiency, and technically-minded drivers who are curious about their vehicle’s inner workings. It’s for the person who sees “Check Engine” not as a panic button, but as a starting point for investigation. Key details include support for both iOS and Android, compatibility with OBD2 protocols used by most cars from 1996 onward in the US, and a focus on accessing not just generic OBD2 data, but also enhanced, manufacturer-specific parameters on many makes and models. The app itself is a one-time purchase, separate from the required OBD2 adapter hardware.

Key Features & Performance
In my experience, DashCommand’s power becomes apparent when you move past the basics and start building your own diagnostic workspace. The features are built for action, not just observation.
Fully Customizable Dashboard and Gauges
This is the heart of DashCommand. You aren’t stuck with a pre-set screen. You can build multiple dashboards from scratch, choosing from a massive library of digital and analog-style gauges. I created one for general driving with coolant temp, fuel economy, and load, and another for performance monitoring with turbo boost, ignition timing, and air/fuel ratios. The ability to resize, recolor, and arrange gauges exactly how you want them is a game-changer for usability. The performance in this area is flawless; gauges update in real-time with minimal lag on a good adapter, making the phone feel like an integrated part of the vehicle’s instrument cluster.
Advanced Data Logging and Export
Where basic apps show you data, DashCommand lets you capture and analyze it. The logging function can record hundreds of parameters simultaneously to a CSV file. I used this to diagnose an intermittent misfire by logging all cylinder trim data and ignition parameters during a specific driving condition, then reviewing the graphs on my computer later. This feature alone provides the kind of diagnostic capability usually found in tools costing much more. Exporting is straightforward, and the data is clean and ready for spreadsheet analysis.
Performance Testing and Calculations
For the enthusiast, the built-in performance tools are a fantastic addition. The accelerometer-based 0-60 and 1/4 mile timers are surprisingly accurate when calibrated correctly. More impressive are the calculated metrics like horsepower and torque, which use vehicle weight and acceleration data to provide estimates. While not as precise as a dyno, they are excellent for showing relative gains after modifications or for tracking consistency. I found these tools reliable and fun to use, adding a quantitative measure to seat-of-the-pants feelings.
Enhanced Diagnostic Trouble Code (DTC) Access
While it reads and clears standard OBD2 codes like any app, DashCommand often goes further on supported vehicles. It can access manufacturer-specific codes and, crucially, provide a much more detailed freeze frame data snapshot when a fault occurs. This means you can see the exact engine conditions (RPM, load, temperature, etc.) at the moment the computer set the code, which is invaluable for diagnosing intermittent issues. In my testing on a GM vehicle, it provided codes and data that a basic scanner completely missed, pointing directly to a problematic sensor.
Compared to similar products like Torque Pro, DashCommand often feels more polished and purpose-built for in-depth analysis, though Torque might have a slight edge in sheer breadth of plugin support. For the user who values a clean, powerful, and highly customizable interface for serious data monitoring, DashCommand is frequently the superior choice.

Final Verdict
After thoroughly testing DashCommand across different vehicles and use cases, my recommendation is strongly positive for its intended audience. It is not the app for someone who just wants to occasionally clear a simple check engine light and prefers absolute simplicity. For that user, a more basic tool might be less overwhelming. However, for the driver or hobbyist who views vehicle data as crucial, DashCommand is an outstanding investment that massively extends the value of a simple OBD2 adapter.
Pros
- The level of dashboard customization is virtually unmatched in its price range, allowing for a truly personalized monitoring experience.
- Professional-grade data logging turns your phone into a serious diagnostic tool, enabling deep analysis of complex or intermittent problems.
- Access to enhanced parameters and detailed freeze frame data provides diagnostic insights far beyond generic code readers.
- The performance testing features are both useful and engaging, offering quantifiable metrics for driving and modifications.
- Stable, reliable performance with a wide range of compatible adapters when set up correctly.
Cons
- The interface and sheer number of options can be intimidating for beginners or those with minimal technical interest in cars.
- Maximizing its potential requires time to learn and configure dashboards and logging profiles suited to your vehicle.
- Some vehicle-specific advanced features depend on your exact make, model, and year, which can vary.
You should buy DashCommand if you are a DIY mechanic, a performance enthusiast, a data-driven driver focused on efficiency, or simply a car owner who loves to understand and interact with your vehicle on a technical level. It’s perfect for those who already know what terms like “STFT,” “MAP,” or “Ignition Advance” mean and want to monitor them. You should consider a simpler app if your needs are strictly limited to reading and clearing basic OBD2 trouble codes with zero configuration or learning curve. For everyone in the first group, DashCommand remains an excellent OBD2 app that delivers powerful diagnostics and monitoring for 2025 and beyond.
