Their story deserves better than a drawer
Your pet's digital health record.
Keep everything your vet gives you in one place, find any detail again, and get your reminders. Simpler days, for both of you.
Krokyu is an online digital health record for dogs, cats and other pets. It brings together vaccines, visits, treatments, medications, weight, symptoms and documents, and lets you share that history with a vet or a boarding kennel through a temporary link, with no account needed at the other end. Free for one pet, €4.99 a month beyond that.

Weight over time
How do you track a pet’s weight?
