"Has it got bigger?" Here's the photo.
A lump you found in April. A limp that comes and goes. Photograph it each time you check, and six weeks later you have something a vet can actually read.
- Title, where on the body, and when it started
- A photo each time you check it
- An optional measured size in millimetres
- A note with every entry
- Active, monitoring or resolved — history kept either way

Memory is a terrible instrument.
You noticed it "a few weeks ago, maybe". It is "about the same, possibly a bit bigger". Every owner has given that answer, and it is the least useful sentence in the consulting room.
When it started
A real date on the first entry, not a guess made under pressure at the appointment.
Whether it changed
Sizes and photos side by side. Growing, shrinking or stable — visible rather than remembered.
What you tried
Notes on each entry: the cream, the rest, the change of food, and what happened next.

- Photos embedded, not linked
- Alongside the microchip, allergies, history and medications
- Built on your device — works with no signal

A diary is not a diagnosis.
CorePaw does not look at your photos, guess what something is, or tell you whether it needs seeing. It keeps an honest dated record, nothing more. If something worries you, ring your vet — do not wait a fortnight to take another picture.
Symptom diary FAQ
What can I track?
Anything you want to keep an eye on over time — a lump, a limp, a patch of skin, a weepy eye. Each one gets a title, where on the body it is, a status and the date it started.
How does the photo timeline work?
Every time you check it, add a photo, an optional measured size in millimetres and a note. The entries build into a reverse-chronological diary, so the change over weeks is visible at a glance instead of relying on memory.
Why record a size in millimetres?
"It looks a bit bigger" is hard for a vet to act on. "8mm on the 18th, 6mm on the 1st" is not. Any consistent measurement helps — a ruler or a tape next to it in the photo helps more.
What are the statuses?
Active, monitoring and resolved. Resolved ones stay in the record — dimmed rather than deleted — because "she had one of these two years ago and it cleared up" is exactly the sort of thing worth being able to prove.
Where does it show up?
Each tracked symptom appears on the pet screen with its latest photo thumbnail and status, so an ongoing problem is in front of you rather than buried in a menu.
Can my vet see it?
Yes. The whole diary — entries and photos — is embedded in the printable vet health summary, so you can hand over the history rather than describing it.
Is this a diagnosis tool?
No. CorePaw does not assess photos or suggest what something might be. It keeps a clear, dated record so the person qualified to judge has better information to work with. Anything that worries you is a reason to call your vet, not to wait and photograph it.
