Petlog: Pet Health Journal

Your vet asks you to keep a diary — here's one that takes under 20 seconds a day and prints a clean one-page brief for the appointment.

Petlog is the daily health log built for pets with chronic or ongoing conditions — allergies, IBD, thyroid disease, post-surgery recovery, and anything else that needs careful watching.

Most pet apps are for healthy pets. Petlog is for the other ones.

THE 20-SECOND DAILY LOG

Six quick questions. One answer each. Auto-saves as you go — no submit button, no forgotten entries. Tap through appetite, energy, stool, vomiting, a photo, and a note. You're done before the kettle boils. Do it every day and you have a real record, not a pile of guesses.

THE VET BRIEF — YOUR APPOINTMENT SUPERPOWER

Before your next visit, tap "Create Vet Brief". Choose a date window, check which sections to include, and hit Preview. Petlog generates a clean one-page PDF — formatted like a clinical handout, not a screenshot of an app. Appetite trends, energy trends, stool and vomit counts, current medications, upcoming vaccines, and your notes, all on a single page. Hand it to the vet at the door or AirDrop it before you walk in.

Vets will actually read it. That's the point.

HISTORY AT A GLANCE

The calendar heatmap shows every day at once. Warmer cells mean more flags that day — low appetite, loose stool, a vomiting episode. Tap any cell to see the full entry. Swipe left or right to move between months. Spot the week things got worse before you'd consciously noticed a pattern.

TRENDS WITHOUT GUESSWORK

Three metric charts — appetite, energy, stool — over the last 7 or 30 days. When a metric falls below its rolling baseline for five or more days, a callout card appears: "Appetite below normal 5 of last 7 days. Consider mentioning at next visit." Descriptive only, never diagnostic. You bring the context, Petlog brings the data.

MEDICATIONS AND VACCINES IN ONE PLACE

Log current medications with dose and schedule. Track vaccines with administered and due dates. Vaccines due within 60 days show in amber so they don't slip past. The Vet Brief pulls all of this in automatically.

MULTIPLE PETS

Managing more than one animal? Switch between pets in the header. Each pet has its own log, history, trends, and profile. Free tier covers one pet — Pro unlocks unlimited.

CALM BY DESIGN

No streaks. No achievements. No guilt when you miss a day. Petlog is for owners in a difficult situation — a pet with a chronic condition is stressful enough. The app stays out of the way and shows up when you need it.
