Brief
Battery Watcher utilises our BattWatcher product to connect to your car battery and transmits data directly to your phone through a Bluetooth connection to this app. You can view the voltage and health of your battery,the consumption of power per second and run various tests such as the Cranking, Charging and Battery tests to make sure you get the most out of your battery.
Goals
Deliver real-time battery health monitoring and diagnostics with easy-to-understand tests and live data for everyday users and enthusiasts.
The challenge
Battery Watcher needed to deliver accurate, real-time diagnostics from the BattWatcher device to a user’s phone via Bluetooth, while presenting data in a way that was both detailed for enthusiasts and approachable for everyday drivers.
Process
We started by identifying the key performance metrics drivers value most — voltage, health, and power consumption — and mapping out how these should be monitored, displayed, and tested within the app.
Research
Studied key battery performance metrics and typical user behaviors to design meaningful test procedures and intuitive data presentation.
Brand Identity System
The app integrates live battery status with detailed diagnostic tools, including Cranking, Charging, and Battery tests, giving users both quick health checks and deeper performance insights.

Wireframing
Wireframes prioritised a clear hierarchy between at-a-glance metrics and in-depth reports, ensuring users could access both without navigating through unnecessary screens.
UI Design
A clean, data-focused interface was created with clear typography, colour-coded indicators, and intuitive test controls, allowing users to easily interpret results and take action.
Development Process
Optimised for Bluetooth stability and low-latency data transfer, the app was built to handle continuous monitoring without draining device resources, ensuring accurate readings in real time.
