The field toolkit for residential electricians — calculators, troubleshooting, references, and quotes.
How do I unlock the quoting feature?
The calculators, troubleshooting, and reference tools are free forever. The Quote tab is free for a 14-day trial. After that, a single one-time purchase unlocks it permanently — there is no subscription.
I already bought the unlock but it's asking me to pay again.
Open the Quote tab and tap Restore purchase. As long as you're signed in to the same Apple ID you purchased with, your unlock will be restored — including on a new device.
How do I back up my quotes and settings?
In the Quote tab, open Backup & Restore and tap Export backup to save a file you can store or send anywhere. To move to a new phone, install ResiVolt there and use Restore from file.
Is my customer and business information private?
Yes. Everything you enter stays on your device and is never sent to us or any server. See our Privacy Policy for details.
Are the calculators safe to rely on?
ResiVolt is a reference and estimating tool. Always verify results against the current NEC and your local code. It does not replace the judgment of a licensed electrician or a required inspection.
