Let’s work
it out.

Every numeric field is editable. You can work with trip distance, battery used, dashboard range, departure charge, arrival reserve, additional charge, consumption and usable capacity. Valid changes update the connected figures. The departure and reserve sliders offer another way to explore charge levels.

Enter your trip distance, choose your departure charge and set the reserve you want at your destination. Additional charge shows the extra battery charge needed for that scenario. Try a higher departure charge or a different arrival reserve to see how the result changes.

Rangr calculates an amount of charge. It does not select charging stations, plan a route or estimate charging time.

Dashboard range is the estimated distance to an empty battery at the departure charge you enter. Trip range also accounts for the arrival reserve and any additional charge during the trip. A reserve leaves part of the battery available when you arrive.

Values need to be within the supported limits and fit together. Departure charge cannot be lower than arrival reserve, for example. Rangr shows a message when an entry is invalid. When you finish editing, an invalid entry is restored to a valid value.

Yes. Tap the current profile name to open Vehicle profiles, then choose Add profile. You can save separate profiles for multiple electric cars and additional profiles for the same car with different accessories.

A new profile copies the selected profile’s capacity and consumption. Close the list with Done and edit those values for the new car or setup.

Create a separate profile and give it a recognisable name, such as “My car + trailer”. Enter the consumption you expect for that setup. Accessory names do not automatically change consumption; you choose the value used in the calculation.

Open Vehicle profiles and swipe left on a profile to reveal Rename and Delete. Rangr keeps at least one profile, so Delete is available when you have more than one. You can reorder profiles using Edit.
