Log your dog or cat's weight in seconds and watch the trend take shape. PetHealthLog charts every entry over time so a slow gain or a quiet loss shows up early - in kg or pounds, with no account and no internet needed.
Start tracking - it's freePets are very good at hiding when something is wrong, and weight is one of the first numbers to drift before anything else looks off. A cat that has dropped from 4.6 kg to 4.0 kg over a few months has lost more than ten percent of its body weight, yet on any single day it can look exactly the same. A dog that creeps up half a kilo a season ends up carrying real strain on its joints and heart without a dramatic moment you can point to.
The problem is that a number scribbled on a calendar or remembered loosely never becomes a line you can read. You weigh your pet, you think "about the same as last time," and the slow direction of travel slips past you. By the time the change is obvious, it has often been happening for a while.
A pet weight tracker app fixes this by turning each weigh-in into a point on a chart. PetHealthLog does exactly that, and it stays out of your way: it is free, it asks for no account, and it works offline so you can log a weight the moment you step off the scale.
A weight log is only useful if it is fast to add to and easy to read back. Here is how PetHealthLog handles both.
Enter a weight with the date and it lands on a trend chart immediately. Instead of a column of numbers you get a shape - rising, falling or holding steady - that you can take in at a glance and compare against last month.
Switch the unit between kg and lb in settings and every past entry follows. Whether your vet works in metric or imperial, the history reads the way you expect without any manual conversion.
Record appetite and food alongside weight, and note any symptom with a simple 1-to-5 severity. When these sit together you can see whether a diet change or a treatment is moving the number - and bring real context to a vet visit instead of a vague impression.
Export a clean PDF of the weight history and recent records to take to an appointment. A precise trend over months is far more useful to a veterinarian than a single number measured in the waiting room.
Keep a profile for each pet, so a dog and a cat - or a whole multi-pet household - each get their own weight chart. No mixing up whose number is whose.
Weight tracking earns its keep in the situations where small changes carry weight. A senior dog or cat needs steady monitoring because unexplained loss can be the earliest sign of a problem worth investigating. A pet on a vet-recommended weight-loss plan needs to see whether the diet is actually working, week by week. A growing puppy or kitten has a curve worth watching, and a pet recovering from illness needs proof that it is regaining condition.
In each of these, a tidy line beats memory every time. PetHealthLog gives you that line without asking you to create an account, sit through ads, or stay online - so the record is there when you and your vet need to look back.
Your pet's health history is personal, and weighing often happens where signal is poor - a back room at the clinic, a corner of the garage, a trip away from home. An app that needs a login and a live connection can stall in exactly those moments.
PetHealthLog stores everything locally on your device. There is no account to create, nothing is uploaded to a server, and there is no tracking. It opens instantly, logs a weight whether or not you are online, and keeps your records yours. Because the data lives only on your device, you can export a backup any time and restore it on another phone.
Free, offline, and ready the moment you open it.
