What it does
Everything about your charge, one glance away.
Open the app, glance at a widget or raise your wrist. Voltidia answers the questions you actually have about your car.

Charge at a glance
Battery level, range and plug state the moment you open the app, plus the time your charge reaches its target.
- Level, range and plug state

Follows the charge on your Lock Screen
While your car charges, a Live Activity keeps the progress on the Lock Screen and in the Dynamic Island. Local notifications tell you when something matters.

- Notified when a charge starts, stops early or reaches its target
- Notified when the cable is unplugged
-
On your Home Screen and your wrist
Widgets show your own car, with its real render and color, and switch to a different layout while it charges. The Apple Watch app and its complications put the information on your wrist.
- Home Screen widgets with your car's own render and color
- A dedicated layout while charging
- Apple Watch app with complications

- Cost, energy and distance
- Savings compared with a petrol car
- Habits, consumption per 100 km and comparison with earlier periods

On top of that
More than a charge gauge.
Tools for the day you charge at home, and for the day you hit the road.
On the road
A map of charging stations filtered by power and connector, and trip planning with charging stops.
A monthly report worth sharing
A clear summary of the month, shareable as an image. In the first days of a new month you still see the previous one.
Apple Watch
Check the charge from your wrist, with complications on your watch face.
Schedules, explained
Your charging schedules are shown and explained: manual or scheduled, on which days, and the time window when it matters.
Honest about freshness
Data comes from Renault's servers, so it is as fresh as your car's last report. Between readings, the Live Activity and widgets show estimates, marked ≈.
