MooLogue

Ever wondered what cows are really saying? With MooLogue, the daily chatter of the barn comes alive. This engaging, science-backed app lets you explore the hidden world of cow communication through an interactive soundboard of real dairy cow vocalizations.

Developed from cutting-edge research by the MooAnalytica Lab at Dalhousie University, Canada MooLogue offers more than 45 categories of authentic Holstein and Jersey cow calls, captured directly from working dairy farms. From maternal reassurance moos to playful rumbles, from feeding anticipation calls to subtle distress signals, MooLogue reveals the social soundtrack of the barn like never before.

What you will find inside MooLogue:

Dairy farmers who want to better understand animal welfare and detect subtle behavioural changes.
Students and researchers interested in bioacoustics, animal behaviour, and digital agriculture.
Animal lovers and learners who want to connect with the unique voices of the barnyard in a playful but informed way.

Key Features

Over 45 call categories with clear explanations.
Farm-recorded audio validated by animal welfare researchers.
Interactive quizzes for both fun and training.
Works offline, making it useful in barns, classrooms, and research settings.

MooLogue can be described as the Duolingo of cow language—accessible enough for children, practical enough for farmers, and academically grounded for researchers. By blending playful design with scientific accuracy, it transforms casual listening into meaningful learning.

Behind the Scenes

The MooLogue sound library was created using more than 1000 hours of field recordings collected across several dozen Canadian dairy barns. Calls were recorded in key farm environments including feeding stations, water troughs, hay areas, and milking parlours. Each sound has been carefully categorized into emotional states and social contexts by a research team specializing in livestock bioacoustics. This rigorous process ensures that what you hear is not only authentic, but also scientifically meaningful.
