About this app

OBD Now, in conjunction with an ELM327 chipped scan tool (Bluetooth or Wi-Fi), transforms your Android phone or tablet into a complete OBDII diagnostic tool.

New features

Build 1.0.292 - Mar 10th 2020

Further modified the setting for devices with Notches or Cutouts so as only the OBD screens are modified. Basically all screens from the Setting menus will remain as they were before adding this setting.

Please note there is no change to any screen if your device doesn't have a Notch/Cutout as the setting is ignored for those devices.
