TagMax by CattleMax is an iPhone application designed for farmers and ranchers to streamline cattle management using EID Readers and Weigh Scales. This app, developed by Cattlesoft Inc, connects wirelessly via Bluetooth to compatible EID readers and weigh scale indicators, enabling efficient cattle handling.

The app offers a SESSIONS MODE for scanning cattle as they are worked in the chute, allowing users to create sessions, record individual animal scans with date/time and GPS location, and even automatically capture an animal's weight from a connected scale indicator. Additionally, the CATTLEMAX MODE facilitates quick access to cattle records within the CattleMax cattle management software, requiring an active CattleMax account and an Internet connection.
