Why it works
The calculator and the field worksheet in one tool.
Most apps do either code math or job notes. BaseCalc Electric keeps voltage drop, wire size, conduit fill, service load, materials, and worksheet capture in the same field workflow.
Capture the worksheet
Keep scope, quantities, site notes, and calculation context in one local job record.
Hand billing to SpeakSheet
BaseCalc Electric stays focused on field math and job worksheets. SpeakSheet stays the final invoice app.

Development status
Built and tested. Not in the stores yet.
We keep this honest: BaseCalc Electric is a finished, tested build, but it is not publicly downloadable today. The remaining work is final store setup, submission, and the launch decision.
Done
Core app tested
All 18 calculators, history, job contacts, worksheets, materials, and PDF export are implemented. The calculator engine test suite covers the field tools.
Done
Local-first privacy model
The v1 launch workflow stores job contacts, worksheets, settings, and calculations on device. No BaseCalc Electric account or cloud sync is required.
In progress
Store submission next
BaseCalc Electric is not publicly available yet. The App Store and Google Play records still need final review setup and submission.
In progress
SpeakSheet boundary is intentional
BaseCalc Electric captures the field worksheet. SpeakSheet remains the customer-facing invoice and billing product.
FAQ
Before you wait for launch.
BaseCalc Electric is a professional reference tool. Always verify against the current NEC and your local amendments.
Is BaseCalc Electric available to download?
Not yet. The iOS and Android builds are complete and tested, but the App Store and Google Play listings still need their first manual setup before the app goes into review. It is not publicly downloadable today.
Which calculations does it cover?
18 NEC-aware calculators: Ohm's Law, Voltage Drop, Wire Size, Conduit Fill, Conduit Size, Box Fill, Conduit Bend, Bend Layout, Service Load, Breaker + Wire, Grounding, Motor Circuit, Pull Box, Derating, EV Charger, Generator, Transformer, and Power.
Does it do invoicing too?
No. BaseCalc Electric intentionally stops at job worksheets: scope, quantities, site notes, calculation history, and worksheet PDFs. Final customer invoices belong in SpeakSheet.
Does it work offline?
Yes. Calculations, history, job contacts, worksheets, settings, and PDF export are designed to work offline in the v1 launch build. No BaseCalc Electric account is required.
How much will it cost?
The initial launch path can stay free and local-first. Subscriptions or ads should only be disclosed if they are intentionally enabled in the submitted build.
Can I rely on it for code compliance?
BaseCalc Electric is a professional reference tool. Always verify results against the current National Electrical Code and your local amendments. The authority having jurisdiction has the final say.
