For car enthusiasts and DIY mechanics who are part of the Apple ecosystem, the question of using an iPhone or iPad for OBD2 diagnostics often arises. The good news is, yes, it is possible to use your iPhone with an OBD2 Bluetooth adapter for car diagnostics, but it requires a few extra steps compared to Android devices, particularly if you want to unlock the full potential. This involves jailbreaking your iOS device and understanding the app landscape available.
The primary hurdle for iPhone users is Apple’s closed ecosystem, which traditionally restricts direct Bluetooth communication with OBD2 adapters. Unlike Android, where apps like Torque can seamlessly connect to OBD2 readers, iPhones require a workaround to establish this connection. This workaround often involves jailbreaking your iPhone, which allows you to bypass Apple’s restrictions and install software from outside the official App Store, such as Cydia.

Jailbreaking and Bluetooth Connectivity
Jailbreaking your iPhone essentially grants you root access to the operating system. In the context of OBD2 Bluetooth, jailbreaking historically allowed the installation of tweaks or apps, like the mentioned RoqueBT4 (though its current relevance should be verified as iOS evolves), to facilitate the Bluetooth connection between your iPhone and the OBD2 adapter. It’s crucial to understand that jailbreaking comes with its own set of considerations, including potential security risks and voiding your device’s warranty. Proceed with caution and ensure you are fully informed before jailbreaking your device.
OBD2 Apps for Jailbroken iPhones: Navigating the App Store
Once your iPhone is jailbroken and configured for Bluetooth OBD2 communication, the next step is choosing the right OBD2 application. While the Android world boasts free or very affordable options, the iOS App Store, even for jailbroken devices, tends to lean towards more premium priced applications for comprehensive OBD2 diagnostics.
Two prominent apps frequently mentioned in the context of iOS OBD2 diagnostics are DashCommand and Rev.
-
DashCommand: Often considered the gold standard for iOS OBD2 apps, DashCommand offers a rich feature set, including live data monitoring, trouble code reading and clearing, performance gauges, and customizable dashboards. Its polished interface and comprehensive functionality come at a higher price point, typically around $40 USD (or 40 quid as referenced in the original context). While it’s a significant investment compared to Android options, users often praise its reliability and extensive capabilities.
-
Rev (and Rev Lite): Rev is another well-regarded OBD2 app for iOS. It shares many features with DashCommand, offering live data, code reading, and performance monitoring. A free “Rev Lite” version is available, primarily for iPhones, but its suitability for iPads may be limited due to potential pixelation issues on larger screens, as noted in the original discussion. The full version of Rev, while less expensive than DashCommand at around $30 USD (or 30 quid), still represents a considerable cost compared to Android alternatives.
Cost Considerations and Android Alternatives
The original article rightly points out the cost disparity between iOS and Android OBD2 solutions. On Android, apps like Torque Pro, praised for their functionality and community support, are available for a fraction of the cost (around $5 USD or a fiver). This significant price difference is a key factor for many users to consider.
For users primarily focused on OBD2 diagnostics and less invested in the Apple ecosystem for this specific task, an Android device paired with a budget-friendly app like Torque may present a more economical and readily accessible solution.
Conclusion: Weighing Your Options for iPhone OBD2 Diagnostics
In summary, using your iPhone with an OBD2 Bluetooth adapter for car diagnostics is achievable, particularly with jailbreaking and utilizing apps like DashCommand or Rev. However, it’s essential to be aware of the associated costs, primarily the price of feature-rich OBD2 apps in the iOS environment.
Before embarking on this path, carefully weigh the pros and cons:
- Pros: Utilize your existing iPhone or iPad, potentially powerful and feature-rich apps like DashCommand.
- Cons: Necessity of jailbreaking (with associated risks), higher app costs compared to Android, potentially more complex setup process.
Ultimately, the best choice depends on your individual needs, technical comfort level with jailbreaking, budget, and existing mobile device ecosystem. For those deeply invested in Apple and willing to invest in premium apps, iPhone OBD2 diagnostics is a viable option. For those prioritizing budget and simplicity, an Android-based solution might be more appealing.
