Vivlo tracks your puppy's growth, feeding and routine through their first year, and answers the questions every new owner asks from your own dog's weigh-ins, not a breed average. Honest about how sure it is, private by default, and grounded in vet science.
Hi everyone,
I built Vivlo after getting our own puppy (Ripple) and realised quickly how I was depending on multiple google searches with varied answers for food, training & growth.
Vivlo answers those questions from your own puppy's numbers instead of generic averages. You weigh your puppy each week and it shows growth as a clear trend, with an adult-size estimate shown as a confidence range that narrows as you add weigh-ins, rather than one invented number.
It works out how much to feed using the same energy formula vets use, learns their daily toilet rhythm so toilet-break reminders land at the right time, and keeps vaccinations and worming on schedule. There's also Ask Pip, a place to ask the everyday "is this normal?" questions, which will always tell you when something is one for the vet rather than the app.
A bit on what's under the hood, because it mattered to me that the numbers are real and not made up:
Growth: breed sizes come from published Kennel Club and AKC breed standards, fitted to a proper growth curve (the S-shaped curve puppies actually grow along), then blended with your own weigh-ins as they come in. That's why the adult-size estimate is a confidence range, not a guess. It earns its confidence from your data.
Feeding: the standard veterinary energy formula (resting energy requirement), the same maths a vet practice uses, adjusted for your puppy's stage and eased slightly for large and giant breeds to protect growing joints. Treats are tracked against the vet's 10% rule, and you get a nudge before the food bag runs out.
Body condition: the 9-point body condition score vets do by hand, walked through in about a minute, because the scales alone can't tell you if a dog is the right shape.
And the bits that make the week easier:
One-tap logging for wees, poos, walks and sleep, with a history view and a one-tap PDF you can hand to your vet. Everything can be logged from a shortcut by holding down the app on your home screen too.
Walk tracking, plus a heads-up on when it's actually safe to start walking after their jabs.
A weekly letter: a short, warm summary of how your puppy's week went and how they're growing.
Family sharing, so everyone in the house sees the same info and logs, not just whoever installed it.
Two things mattered from the start: it had to be honest (it builds insight from your puppy's real data and never presents a guess as a prediction) and it's built to sit alongside your vet, not instead of them, the app doesnt diagnose. It helps you notice changes early, describe them clearly and turn up with the actual numbers, so it helps the conversation with your vet rather than getting in the way. Anytime your puppy seems unwell or you're worried, it points you straight to them.
I'd really love your thoughts, especially from anyone who's raised a puppy.
What did you worry about most in that first year? Happy to answer anything.
