CANviewer vs Electric Scan

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 • Import ASC-style text (including compatible ASV), supported Vector BLF objects, PCAN TRC and header-based CSV logs • Filter raw frames by CAN ID, Rx/Tx direction and channel • Import DBC files and decode their signal definitions • Plot decoded signal values as charts • Open a matching sample log and DBC with one tap, without using your free quota • Follow the first preferred system language (Chinese or English; otherwise English), with a persistent manual override • Pro: save local log/DBC copies and chart selections across restarts • 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.

Electric Scan turns your phone into a live window on your EV's high-voltage battery. Pair it with the Electric Scan Bluetooth LE module, connect the module to your vehicle, and the app streams what the battery management system reports, refreshed several times a second. CELL VOLTAGES Every cell in the pack, read individually. Switch between a numeric grid and a heatmap that shows at a glance where each cell sits within the pack's own minimum-maximum range. The summary panel identifies the highest and lowest cell by number, the pack average, and the spread between them in millivolts. PACK AND STATE State of charge, state of health, total pack voltage, module temperatures, and 12 V system voltage, each on its own level bar. DRIVE DATA Motor RPM on a 270-degree gauge, actual against requested torque on a bipolar meter that separates drive from regeneration, and GPS speed from your phone. TRIP RECORDER Start a recording before you set off and the app samples speed, RPM, state of charge, and torque for the whole trip. Afterwards you get distance, top and average speed, peak RPM, and the change in state of charge, with a chart for each channel. Trips are stored on your device and you choose which ones to keep or delete. G-FORCE METER A live readout of acceleration, braking, and cornering forces measured by your phone's motion sensors, with a trail of recent movement and a peak hold. LANGUAGES Thai and English. REQUIRES HARDWARE Electric Scan is a companion app for the Electric Scan Bluetooth LE module and does nothing on its own. Without the module connected to a vehicle you will only see the connection screen. IMPORTANT Electric Scan displays the values your vehicle makes available. It is a reference tool for the owner, not a repair tool, and it cannot repair or resolve high-voltage battery issues. The readings shown are preliminary reference information only and are not a substitute for an official diagnosis by an authorised service centre or a qualified technician.
