Nibble - pet weight loss plan
Safe weight loss for cats&dogs
Free · Designed for iPad. Not verified for macOS.
Nibble isn't a weight logbook — it's a weight-loss coach that lives in your pocket.
More than half of all cats and dogs are overweight, and most owners don't realize it. Nibble uses the Body Condition Score (BCS) that vets rely on to help you see your pet clearly, then lays out a safe, science-based plan you can actually stick to.
FIND OUT IF YOUR PET IS OVERWEIGHT
· Feel the ribs, check the waist: BCS 1–9 self-assessment with illustrations that morph as you score
· Risk alerts based on breed, neutering, age and activity level
KNOW EXACTLY HOW MUCH TO FEED — IN GRAMS
· Daily calorie budget computed from the target weight
· Enter the calorie density from your food bag and the budget turns into grams per day and per meal
· A separate treat allowance (≤10% of calories) with one-tap logging and custom treats by weight
SAFETY FIRST
· Hard guardrails on weekly weight loss: ≤1.5% for dogs, ≤0.7% for cats
· Cats must never lose weight fast — Nibble enforces this rule at every step
· All numbers are reasonable starting points, not medical advice. Confirm the plan with your vet before starting.
BUILT FOR THE LONG HAUL
· Trend line and milestones, with instant coach feedback after every weigh-in
· Plateau explanations right when motivation is most fragile
· Monthly photo comparisons so you can see the change
· A home-screen widget that keeps progress in sight
· Maintenance mode kicks in at goal weight to prevent rebound
YOUR DATA STAYS YOURS
· Fully offline. No account. No data collection.
Losing the weight is the easy part — keeping it off is what counts. Start with a BCS score today.
