Patter: a nutrition app for cats and dogs.
Patter brings meal logging, calorie tracking and nutrition analysis together for cats and dogs. Record food, water and weight, and get guidance informed by your pet’s profile and care history.
Available on iPhone and Android.

Keep meals and feeding plans together
Record what your pet eats and organise their feeding plan in the same app. Plan portions, distribute multiple foods across meals and feeding times, and edit the plan as their routine changes.
Log extra foods separately from planned meals, so an additional snack has a place in the record too. Whether you are keeping a food diary for a cat or tracking a dog’s meals, Patter connects those entries with the individual pet’s nutrition analysis.
Understand calories and nutrients
Track calories and see analysis of macronutrients and micronutrients alongside the food your pet eats. Patter uses their age, weight, allergies and known conditions as context for personalised nutrition guidance.
A real example from Milo’s nutrition screen
The screen above shows Milo’s logged chicken pâté and salmon kibble, nutrient amounts and a weekly calorie trend. Its weekly note connects feeding with training: set aside some of Milo’s planned kibble for recall rewards, keeping those rewards within the same daily allowance.
That is an example of guidance for Milo, rather than a feeding prescription for another pet. Nutrient values are estimates based on the food information available, not laboratory measurements of the food in your kitchen.
Follow food intake alongside weight history
Keep weight records alongside nutrition history. Patter interprets weight trends, helping you understand the record rather than only storing a series of weigh-ins.
Your veterinarian sets appropriate weight targets and safe rates of change. Our guide to pet weight and body condition explains why the number on the scale is only part of that conversation. If eating habits change, the appetite changes guide covers useful observations to record and when to contact your vet.
Record water intake, too
Track water consumption and get analysis alongside food and weight. Keeping these records together gives a change in drinking some context when you review your pet’s routine.
For practical help measuring drinking and understanding the effect of food moisture, see our pet water intake guide. Changes in thirst can also warrant a veterinary conversation.
Use your pet’s profile to inform food choices
Patter’s food-safety assessment considers your pet’s allergies, known conditions, age and profile. That makes the guidance specific to the information you have recorded about your animal.
Keep that information current: the assessment depends on the profile you provide. Prescription and therapeutic diets remain veterinary decisions; Patter does not replace a diet plan your veterinarian has set.
Give nutrition a place in the whole care picture
A food entry is more useful when you can consider it alongside the rest of your pet’s history. Nutrition, weight and water intake connect with health in Patter, while the AI assistant can use relevant profile and nutrition history when you ask about your pet’s diet.
Nutrition is one of Patter’s six connected care areas, alongside Health, Mood, Training, AI Chat and Reminders. Explore care for cats or dogs, or read how Patter supports veterinary care.
