Best pet health tracker apps for dogs and cats, compared
A tracker is only as good as the log behind it. These four take very different views of who gets to write to that log.
A health tracker earns its keep on the second visit. One weight is a number. Twelve of them are a trend, and a trend is the thing a vet can act on.
That only works when the log is complete, and in a house where two people share the animal it usually is not. One of you records the Tuesday weigh-in, the other covers Saturday and never opens the app, and the chart ends up describing a caregiver’s week.
So the row this page starts from is who can write to the record, and what the record remembers about them. Every cell below repeats what each app advertises in its own public materials, with a dash meaning "not advertised" rather than "absent". Check the current listings before you decide, because apps change.

What makes a weight trend worth showing a vet?
Three things, and only one of them is about the app. Weigh on the same scale, weigh at roughly the same interval, and record every weighing, including the ones somebody else was home for.
The third is where a shared household loses the plot. A chart with half the entries missing still looks healthy, because the gaps flatten it into a pet whose weight seems stable. That is the failure mode worth designing against, and it is why this comparison leads on who can write to the log before it counts anybody’s fields.
The same logic runs through medication. A dose is only on the record if the person who gave it recorded it, and a reminder that keeps firing after somebody has already acted teaches the household to ignore reminders.
Which one should you pick?
One person, one pet, and you want the record to be thorough. Vet Record and 11pets both advertise deep histories with reminders, and both have a free tier. 11pets goes further on the number of fields; Vet Record is squarely about the medical record and getting it out again as a link.
A new puppy and a household that wants to talk about it. DogLog turns the day into a feed you can post photos to and comment on, and lets you invent your own event types. Neither of those exists in Dana, and for the first few months of a puppy they are a pleasure to have.
More than one person caring for the same animal, indefinitely. That is the case Dana is built around. Every feed, walk and pill carries the caregiver and the time, one person logging a task quiets its reminder for the whole household, and a sitter can be given access that closes on a date you set. Caregiver sharing is on the free plan rather than behind the paywall.
Questions about this, answered
What should I actually track month to month?
Weight, on the same scale and at a steady interval, plus the next due date for every vaccine and recurring medication. The weight trend is one of the most useful things an owner can hand a vet, and due dates are what turn a lapsed booster into a booked appointment.
Does a free plan usually cover more than one caregiver?
It varies, and it is the question worth asking first. In Dana, unlimited pets and unlimited caregivers with attribution are on the free plan. Elsewhere, read the free tier for where its limit sits, because a tracker that only one of you can write to will draw an incomplete chart.
Can I keep the certificate itself, not just the date?
In Dana, yes, in the Records Vault, which ships with Pro. The dates, doses, weights and vet details are on the free plan; the Vault is for the scanned documents, and it shares through a code-gated link that expires, so the clinic needs no account.
Do I need my vet to use the same app?
Not for any of these four. Clinic portals such as PetDesk are the exception and they work the other way round: your practice buys the software and you get the patient app, which is why the link dies if you change vets.
Where to go from here
The two apps above that share care deliberately each have a page of their own: Dana vs DogLog: two apps built for more than one person and Dana vs 11pets: exhaustive tracking, or shared care. The wider category, including the clinic portals, is in Best pet care apps in 2026, compared honestly.
Two newer apps start from coordination rather than from the health record, which makes them the closest comparison on this site: Dana vs Pawlo: shared pet care, with or without the records and Dana vs Team Pet: where each free plan stops. Neither advertises a weight series or document storage, so they sit outside the table above on purpose.
What to keep and how to get copies out of your clinic is in our guide to pet health records. What Dana itself costs is on the pricing page.
Before choosing where your documents will live, check that you can keep and recover your own backup. A medical history summary with dated sourceshelps a clinic navigate those documents.
The same file has to answer an insurer's pre-approval request before a treatment and a clinic's question about an unpaid bill after it.
