Electrician apps split into two kinds that get searched for with the same words. Business apps run the shop: the price book, the estimate, the invoice, the schedule and the customer record. Reference apps are the electrician's technical bench: code lookups, wire sizing, voltage drop and load calculations. This site is the business kind, deliberately, and six of its tools are free; the reference kind is a different product for a different moment in the day.
The business apps run the day
On a phone in the driveway an electrician needs the customer's history, the price book, the estimate approved with a signature, the work recorded, the invoice raised and the payment taken. Those six things are the business apps, and the point is that none of them needs the office. The record they hang off is the paid product; the documents are free here.
The reference apps are the bench
Wire sizing, voltage drop, ampacity tables and code questions are the electrician's technical reference, used at the panel rather than at the customer's kitchen table. They are a different product, and this site does not carry them until a measured row and a licensed source put one here.
Which ones are free on this site
Cost calculator, estimate calculator, invoice, price book, receipt template and residential price list. Each computes its answer on the page with no account and no trial clock; the subscription is for keeping, branding and sharing what they produce.
The trade these apps serve
The Bureau of Labor Statistics' occupational outlook for electricians, cited below, describes the working day the business apps are built for: service calls, installations and repairs at customers' properties, often alone, with the paperwork done wherever there is signal.
Questions people ask about electrician apps
Which electrician apps are free?
On this site: cost calculator, estimate calculator, invoice, price book, receipt template and residential price list. None needs an account.
Do I need a separate app for the office?
No. The electrician does the job end to end from the phone; the office sees the same record without re-typing anything.
What about code and calculation apps?
They are reference tools, not business tools, and mostly outside what this site covers today.
