Cat Weight Tracker

A cat's weight is the most accessible health signal you can track at home. But cats don't sit on scales, and logs don't get kept — so this app is built to make it stick.

■ Weigh while holding
Pick up your cat and step on the scale. Enter the total, and the app subtracts your registered weight to get your cat's. Readings from pet scales, baby scales, and the vet all go into the same graph.

■ Three seconds per entry
The last value is pre-filled, so a few taps on +10g / -10g is all it takes. Hold to move faster. A home-screen widget shows the latest weight and the change since last time.

■ Loss matters more than gain
Unlike people, weight loss is the more worrying sign in cats. This app never congratulates a drop. It watches both directions and quietly flags changes such as a 3% loss over 4 weeks, a 5% loss over 8 weeks, or a 10% drop from the six-month high.

The thresholds and their sources (WSAVA, AAHA, and others) are published in full inside the app.

Alerts are not a diagnosis. If something concerns you, please consult your veterinarian.
