## What is Purrfect RR?

Purrfect RR helps you look after a cat you are worried about.

It starts with the number your vet asks for first: the resting respiratory rate. Counting breaths while your cat sleeps is one of the earliest ways to notice change in a cat living with heart disease. It is also easy to lose track of at two in the morning, tired, counting in your head. Purrfect RR holds the count for you.

TAP ONCE PER BREATH
• Tap the big circle each time your cat breathes — the app does the math
• 30 seconds, 60 seconds, or continuous with no timer
• A breathing ring and a reference scope help you keep an even rhythm
• Note whether they were sleeping, resting, or awake, plus symptoms and a comment
• A quiet card lets you know when sleeping RR has been running high

CARE PACKS
Turn on the packs that match your cat — Cardiomyopathy, CKD, Diabetes, Asthma, or Comfort Care. Each one brings its own metrics and a focus card, so the number you check every day sits on the home screen. Turning a pack off never deletes anything you have already logged.

NINE METRICS, EIGHT INSTRUMENTS
Weight, food, meals, appetite, water, SubQ fluids, blood glucose, coughing, and a weekly quality-of-life check-in. Each one has its own instrument instead of a blank text field: drag the level in a saline bag, click a tally counter, tap plates on a meal tray, turn a scale dial. The CARE tab gathers whichever instruments your cat needs onto one screen.

MEDICATION
• Every 8, 12, or 24 hours, or a schedule you set yourself
• Bundles for multi-drug routines, or one drug at a time
• A preset library of common feline heart medications, with a dose calculator down to 1/32 of a tablet
• A reminder 15 minutes ahead — log the dose straight from the lock screen

VACCINE BOOK
A passport-style book with a card per vaccine: date given, next due, lot number, and a reminder when the date comes around.

FOR THE NEXT VISIT
Trends show RR over time with dose times marked, plus sleeping-RR medians over 7 and 30 days. The calendar colour-codes each day. When an appointment comes up, export a PDF — charts, session logs, and 30-day summaries — and bring the whole picture with you.

YOUR DATA STAYS YOURS
Daily automatic backups, optional iCloud copies, and full export and import. No account, no ads. Nothing leaves your phone unless you send it.

Purrfect RR is a tracking aid, not a medical device. It does not diagnose, treat, or prevent any condition. Please talk to your veterinarian about your pet's care, and see one right away if your pet is in distress.


## Version history (last 4 releases)

### 2.0.1 — 2026-08-30

Fixes for the vaccine book, thanks to an owner who wrote in:
• A vaccine no longer stays marked "Overdue" once you log the next dose — its status now follows the most recent dose, the way a paper booklet reads
• "Next due" on the book cover now shows the newest dose's date, not an old date that was already taken care of
• A dose due today reads "Due soon" for the whole day, instead of turning overdue at midnight
• Vaccine reminders no longer fire for a booster your cat has already had
If something in the app doesn't match what's true for your cat, tell us — this update exists because someone did.

• A new CARE tab that gathers your cat's instruments onto one screen
• Focus cards keep the number you check daily two taps from the home screen
• Weight can now be logged and reviewed for every cat, not only cats with a Health tab
