The quickest way is “Report this result” under the result in the app. It opens your mail app with the calculator, the formula version and the numbers on screen already filled in.

If you write from somewhere else, please include:

• the calculator, and the mode if it has one (for example CRI, fluid bag)
• every value you entered, with its unit
• the result Vetrule showed, and the result you expected
• where your expected number comes from: guideline, textbook or label, with the year or page
• the app version (Settings › About Vetrule) and your device’s region

Please leave out owner and patient names. Send it to hello@vetrule.com. Corrections are listed in the change log.

Does Vetrule work offline?

Yes. Every calculation runs on your iPhone or iPad and needs no network. Only buying or restoring Vetrule Pro goes through the App Store.

What data does Vetrule collect?

None. There is no account and no analytics. Patient names and weights stay on your device and in your own backups. Details are on the Privacy page.

Which guidelines does it follow?

Each calculator names its own. Energy follows the AAHA 2021 Nutrition and Weight Management Guidelines; fluids, potassium and shock bolus the 2024 AAHA Fluid Therapy Guidelines; CRI Grubb (IVAPM 2023); transfusion, BSA and due date the Merck Veterinary Manual; cat age the AAFP–AAHA feline life stage guidelines. Every source, with its year and a link, is on Formulas and sources.

Does Vetrule suggest doses?

No. It converts the dose the vet orders and the strength on the label into a volume or a rate. Treatment decisions stay with the veterinarian.
