We are pleased to offer you a free and professional OBD II scanner app. Thank you for participating in the testing phase; we greatly appreciate your feedback and input. Please note that this app is still under development and may not yet be fully optimized, so you may encounter bugs or issues. Currently, only OBDCheck BLE and OBDCheck BLE+ are supported. If the app does not include the features you need or if you experience difficulties using it, please report the problems to us. In the meantime, we recommend trying alternative apps, such as Car Scanner ELM OBD2, as suggested in the user manual.
