# PoEHeat PoEHeat is an offline Android app by Anvilfield for structured cabling, AV, and low-voltage security teams. Core job: chain conduit fill, NEC 725.144 bundle derating, cable temperature rise, voltage drop, and the IEEE 802.3bt power budget into one signed PoE run sheet that names the limiting factor. Price: free for three runs; Pro is a one-time $9.99 unlock for unlimited runs, signed run sheets, and whole-job commissioning records. No subscription. Offline behavior: the calculation engine, saved projects, rule libraries, PDF generation, and PNG diagram generation run on the device. Play Billing restore, in-app review, and Android share or print services may use platform network access when available. Publisher: Anvilfield.
