Nibble: Pet Weight Tracker
Dog & Cat Weight Loss Plan
Free · Designed for iPad. Not verified for macOS.
See how many grams to feed today, tap each meal as it's served, and keep weight loss at a pace that stays safe for dogs and cats.
Nibble helps dogs and cats lose weight safely — and tells you exactly how much to feed today.
Score your pet's body condition, enter the calories printed on the food bag, and Nibble turns it into grams per meal. Tap each meal as you serve it, keep treats inside a small daily allowance, and weigh in once a week. Nibble watches the pace so your pet never loses too fast.
TODAY'S MEALS, AT A GLANCE
· Grams per day and per meal, worked out from your food's calories
· Tap a meal once it's served — in the app or right from the Home Screen widget
· Optional scoop or cup conversion: weigh your scoop once, then see "≈ ½ cup"
KNOW WHERE YOUR PET STANDS
· Body Condition Score (BCS 1–9) with illustrations that change as you score
· Risk notes based on breed, neutering, age and activity
A PACE THAT STAYS SAFE
· Weekly loss guardrails: at most 1.5% for dogs and 0.7% for cats
· Cats must never lose weight fast — Nibble flags it right away
· A coach note after every weigh-in: steady, too fast, plateau or below target
TREATS WITHOUT GUESSWORK
· A separate treat allowance of up to 10% of daily calories
· Low-calorie treat ideas with one-tap logging, undo and portion edits
WEIGH-INS MADE EASY
· Can't weigh your pet alone? Step on the scale holding them — Nibble subtracts your weight
· Add a weigh-in you missed, fix or delete an entry
· Trend line, milestones and monthly photo comparisons
EXPORT & SHARE
· A one-page weight report (PDF) to bring to checkups, plus a CSV of every weigh-in and treat
YOURS, AND ONLY YOURS
· No account and no ads. Your records stay on your device.
Nibble gives everyday reference numbers, not medical advice. Please confirm the target weight and pace with your vet before you start.
