User Reviews

JB4 Mobile is praised for its feature-rich gauges, real-time data, and strong JB4 hardware integration, plus a supportive community. However, recurring issues include iOS 26 causing the screen to sleep, connectivity/logging problems after updates, mandatory UI changes that remove customization, and ongoing requests for CarPlay support; licensing concerns about repurchasing the app.

Pros

Feature-rich capabilities including gauges, real-time data, logs, and map switching.
Real-time gauges and comprehensive logs provide valuable feedback.
Strong JB4 hardware integration allowing on-the-fly tuning.
Responsive community/support forums for help.

Cons

iOS 26: screen keeps turning off or auto-locks during gauge use; no fix or setting.
Connectivity and logging issues after updates; cannot connect or download logs.
Mandatory updates that drastically change the UI and remove customization; users want option to stay with previous version.
Lack of CarPlay integration; users want CarPlay support.
Need to repurchase or re-license the app after changing devices.
