Electricity: Expert for iPhone

Quick summary

Electricity: Expert is an iPhone utility that helps you estimate and monitor electrical consumption. It streamlines calculations so you can see how much power your appliances use and what that translates to in cost.

How to use the app

• Enter how many hours per day each device runs and how many of those devices are in use.
• Choose a device from the built-in list to have its wattage filled in automatically, or type in the wattage yourself if the item is not listed.
• Provide the number of days you want the calculation to cover and the rate you pay per kilowatt-hour.

Main capabilities

• Calculates estimated energy use and cost based on your inputs.
• Offers automatic wattage suggestions for common appliances to speed up setup.
• Accepts multiple devices and quantities so totals reflect real-world usage.
• Simple, clear data entry fields designed for quick results.

Practical tips

• If you have an electricity meter, record readings before and after a test period to verify the app’s estimates.
• For devices with variable power (like laptops or dimmable lights), use a measured or averaged wattage to improve accuracy.
• Save common device setups to reuse them for repeated comparisons or seasonal checks.

Goal of the app

The aim is to make energy tracking accessible without needing technical expertise — helping you identify high-usage appliances and make informed decisions about reducing consumption.
