LiLog vs CANviewer

LiLog is a mobile CAN log analysis tool designed for automotive ECU engineers, testers, and developers. Analyze CAN traces directly on your iPhone or iPad without carrying a laptop. Quickly inspect messages, decode signals with DBC files, and troubleshoot vehicle issues anytime, anywhere. FEATURES • Offline CAN Log Analysis View and analyze CAN logs locally without requiring a network connection. • DBC Signal Decoding Import DBC files and decode raw CAN frames into readable engineering signals. • Fast Filtering & Search Quickly filter messages and locate important signals in large log files. • Multi-Format Log Support Supports common CAN log formats used in automotive development and testing workflows. • Mobile Engineering Workflow Ideal for vehicle testing, road tests, ECU debugging, integration testing, and issue investigation. BUILT FOR AUTOMOTIVE ENGINEERS LiLog focuses on real engineering workflows instead of generic OBD monitoring tools. Whether you are working on ECU development, CAN network debugging, validation testing, or field troubleshooting, LiLog helps reduce the time required to inspect logs and locate abnormal vehicle behavior. Carry a lightweight CAN analysis tool in your pocket and analyze logs wherever your work takes you.

CANviewer is a CAN log viewing tool designed for automotive electronics, ECU debugging, and field analysis. You can import ASC and BLF CAN logs on iPhone, quickly view message time, CAN ID, direction, channel, DLC, and data bytes, and filter the messages you need by CAN ID, Rx/Tx, and channel. After importing a DBC file, CANviewer can decode raw CAN data based on the signal definitions in the DBC file, convert hexadecimal data into physical values, and plot signal trends over time. Key features: - Import and view ASC / BLF CAN logs - Filter messages by CAN ID, Rx/Tx, and channel - Import DBC files and parse messages and signals - Decode CAN data into physical signal values - Compare multiple signal curves - View curves in combined or separate charts - Display X/Y axes, units, and data ranges - Tap a curve to inspect the exact time and value - Works offline; imported files are not uploaded Use cases: - Quickly inspect CAN logs in the field - Analyze ECU signal trends - Validate DBC signal definitions - Support vehicle debugging and troubleshooting - Assist engineers during road tests, business trips, and service work CANviewer is not intended to replace complex desktop tools. It is a lightweight and direct mobile tool for CAN log viewing and signal analysis.
