Conduit Fill: NEC Calculator Support

Support

Email support@conduitcalc.txyou.com. Include your device model, iOS version, app version, and what you were doing (Fill, V-Drop, Wire, What pipe?, a purchase, Restore, or Settings).

What is free, and what unlocks

Fill forward on EMT and THHN stays free. One What pipe? lookup and one V-Drop calculation are included per install. The Wire tab, 2023 tables, extra saved jobs, and a clean PDF need the one-time $7.99 unlock. Code year 2026 is available on the free side.

Restore a purchase

Reinstall, then open Settings → Restore purchase. You can also use Restore on the unlock screen. The unlock is tied to the Apple ID that paid. Family Sharing can share a non-consumable if you enabled it in App Store Connect.

The app is offline

After install, Fill, V-Drop, and Wire work in airplane mode. A live purchase needs a network so Apple can charge the Apple ID.
