For reference only
Pata is a reference tool for veterinarians. Formulas, doses, scales and clinical content support clinical reasoning and don't replace professional judgment, the product label, current literature or your country's regulations. Check every value before using it.
Formulas you edit
You can change any formula, dose or constant. By editing, you confirm that you're responsible for the edited formula and the results it produces. The app shows the original next to it and marks "Edited by you" on every result, record, document and export that uses it. App updates never overwrite an edited formula.
Sources
Every formula lists the references it was taken from. Content not yet reviewed by a responsible veterinarian is shown as a draft.
Translations
Pata and its clinical content (drugs, conditions, protocols, formulas) were written in Portuguese and translated into English, Spanish, French, German, Italian and European Portuguese. Translations may contain errors. Doses, numbers and units are the same in every language. If you find a translation error, report it in Settings → Send feedback or report a problem or at suporte@truevet.com.br.
Account and plans
The Free plan covers 1 patient. The Unlimited plan is a monthly or yearly subscription with a free trial for new subscribers, billed by the App Store or Google Play, which you cancel in your store settings.
