Tachwise’s free app beta reads car data through an OBD-II dongle and explains battery health, fault codes, and live readings in plain language.

Landing page captured for the 2026-09-23 issue.

For: Everyday drivers using OBD-II dongles
Worth noticing: The beta needs a Bluetooth LE ELM327 dongle and Chrome on Android or desktop; iPhone support is tied to a native app.

Field notes

The browser beta connects to a Bluetooth Low Energy ELM327 dongle and can read faults and live data while the phone is connected; trips are kept on the phone. The separate Tachwise device is described as a bench prototype, with overnight battery monitoring shown as an intended capability rather than measured product data. The beta requires Chrome on Android or a desktop or laptop with Bluetooth; iPhone support is tied to a future native app.
