Voltmoss: Car Dashboard

Your car, in your pocket.

Voltmoss is the companion app for a car connected through your own j5-ev-dashboard telemetry server. Point it at your server once, unlock it, and everything the web dashboard knows about your car follows you — live.

FOUR TABS, GROUPED BY WHAT YOU ACTUALLY WANT TO KNOW

HOME — Can I drive, how far, and what do I want to do right now? A state-of-charge gauge, real range, parked drain, your car's own photo, and one tap for lock, unlock, A/C, find and stop charging.

ENERGY — What did it cost and where did it go? A live charging curve, a 7-day history you can read as bars or a calendar heatmap, efficiency and trend, and an AC/DC cost planner.

TRIPS — Going somewhere? Plan A to B with charge stops on a real map, browse nearby charging stations with live availability, and look back at your trip history and lifetime stats.

VEHICLE — The car as an object. The full command grid, A/C temperature, a tyre diagram, odometer, 12V health, pack health, service countdown and specs.

EVERY NUMBER, EXPLAINED

Every metric card opens an explainer that shows how the figure was derived, so you are never staring at a number you have to take on faith. Compare running costs against petrol at a price you set yourself. Add a service reminder. Hide your plate and VIN with one tap when someone is looking over your shoulder.

WIDGETS ON YOUR HOME SCREEN

Battery, charging, overview, tyres, conditions and controls widgets in three sizes each — and you choose which buttons each one carries.

THREE DASHBOARDS, ONE CAR

Choose how the app looks: Instrument, the original gauge and cards; Cockpit, a heads-up cluster; or Gallery, an editorial layout. Each one has a light and a dark side.

ROOM TO SPREAD OUT

On a foldable or a large screen the tabs move to the side and Settings opens in two columns. Folded, on the cover screen, every tab stays within reach.

YOUR SERVER, YOUR DATA

Voltmoss is a client, not a service. Your car's data travels only between your phone and the j5-ev-dashboard server you host yourself — no account with us. The only thing we receive is anonymous usage analytics and crash reports, and you can switch those off in Settings.

TRY IT BEFORE YOU CONNECT

No server yet? Type "demo" as the server address and explore the whole app with sample data — entirely on your device.

Available in English, Bahasa Melayu, Bahasa Indonesia and Simplified Chinese. Download Voltmoss and put your car in your pocket.
