About

CANviewer

Features
Read full description

CANviewer is a mobile tool for viewing and analysing CAN-bus logs and DBC signals, designed for vehicle electronics, testing, calibration and service work. KEY FEATURES β€’ Import ASC-style text (including compatible ASV), supported Vector BLF objects, PCAN TRC and header-based CSV logs β€’ Filter raw frames by CAN ID, Rx/Tx direction and channel β€’ Import DBC files and decode their signal definitions β€’ Plot decoded signal values as charts β€’ Open a matching sample log and DBC with one tap, without using your free quota β€’ Follow the first preferred system language (Chinese or English; otherwise English), with a persistent manual override β€’ Pro: save local log/DBC copies and chart selections across restarts β€’ Pro: export every valid original point for selected message signals, independent of chart sampling FREE VERSION AND PRO The free version includes log browsing, filtering and DBC viewing, with 3 chart-session unlocks per day. An unlock lasts for the current chart view's lifetime; signal changes, gestures and redraws do not cost extra. Recreating the view or restarting requires another unlock. Samples are unlimited and do not consume the real-file quota. Umeng Ads is used for mainland-China device regions; Unity Ads is used elsewhere. A launch ad is requested once during a cold start. After a useful chart remains visible for 90 seconds, one additional interstitial opportunity is allowed per foreground session; later returns from background may also be eligible, at least 30 seconds apart. Ads are blocked during import, file picking, export and purchases. A one-time Pro purchase removes ads and adds unlimited charts, local project saving and full signal CSV export. Existing projects can still be opened or deleted; chart access follows current entitlements. FORMAT SCOPE BLF support covers selected classic CAN/CAN FD objects, with visible skip counts for unsupported objects/containers and errors for damaged structures. DBC supports basic integer signals with Intel/Motorola byte order, signedness, factor and offset. Multiplexed and floating-point signals are not supported and are explicitly reported. This is not a full desktop analysis suite or a vehicle diagnostic instrument. PRIVACY Log and DBC files are processed on your device. Advertising SDKs are initialized only in the free version. You may choose whether to allow tracking in the iOS system prompt.
