Works but could be better

The Cattletags app has potential for simple onsite integration of RFID systems. Our major complaint is only two additional data fields (visual ID and weight) are available. If the developers could add additional fields to include Sex, Breed (or Type), Vaccinations, and Notes this would allow the Cowboys onsite to keep better records to report to management or update Cattlemax records when cellular or WiFi is available. We processed 100 new tags/cattle with our trial run of this app and would have appreciated having additional fields. We processes over 3000head a year of new tags/animals and this app would be a great assets with the recommended improvements.
