What Is OBD Fusion?
OBD Fusion is a professional-grade automotive diagnostic tool designed for iOS and Android that enables users to read OBD2 vehicle data, clear check engine lights, and monitor engine health via custom virtual dashboards. It targets a broad spectrum of users, ranging from professional mechanics to DIY enthusiasts who require granular control over vehicle diagnostics and performance tracking.
Positioned as a premium, feature-rich utility, the app distinguishes itself through its deep customization capabilities and support for manufacturer-specific enhanced diagnostics. Currently holding a strong position in the Travel category (Ranked #4 Paid), the app demonstrates high market demand. However, its reputation is currently challenged by a disconnect between user expectations and feature delivery—specifically regarding CarPlay functionality—and a monetization strategy that has caused friction among long-term users.

Works plug-and-play with my Bluetooth adapter for 3.0L Duramax.
Best OBD app on the market... I’ve bought the enhanced packages for 3 vehicles.
Configure every last detail! So fun to use and a great replacement dashboard.
Custom PIDs pull slip RPM, EGT, trans temp, boost, oil pressure... essential for towing.
Top Complaints (Impact Areas)
CarPlay mode does not show any gauges. The entire reason I paid $9.99 for the app.
Need to update and allow real time gauges on CarPlay, not just phone.
Purchased for $9.99 but to get any real functionality, you need to then pay an extra $14.99!
Purchased years ago with reader. It’s worked wonderfully until a few months back where they decided to put all the features behind a paywall.
