Clarity
Everything from your dog’s day in one place. You see when they ate, who took them out, and what has changed lately — without having to ask.
The safety net for everyday dog life
Know what’s going on with your dog.
Koiru keeps feedings, walks, medication and small observations in one shared view — for the whole family, in real time.
Why Koiru?
Because a dog’s day has too much to remember.
Has someone already fed her? Did we go for a walk today? Is the limp new or old? Small questions you don’t always have the answer to. Koiru is built for them — a shared memory for the whole family that quietly keeps things in one place, so you don’t have to.
What Koiru is built for
Clarity, perspective, tracking. That’s what Koiru is built for.
Perspective
When something worries you, you see it in the context of your dog’s own routine. No guessing alone — Koiru helps you tell whether the change is small or worth a vet check.
Tracking
Koiru remembers what an ordinary week looks like for your dog. If the rhythm changes — shorter walks, later meals — you’ll get a heads-up the moment it shows.
Diary
Logging takes seconds.
Feeding, walks, medication or a small observation — one tap and it’s saved.
- See who logged what
- Long-press opens more detailed fields
- Snap the medicine box or the symptom — no typing
Moments
When Koiru steps in.
When the puppy refuses food two days in a row
And you can’t remember when she last ate properly. The timeline shows it instantly.
When Grandma takes Max for a walk and you’re at work
Her entry shows up on your phone right away. No phone calls to check whether the dog has been out.
When you’re not sure if the limp is new
Tassutulkki looks at Max’s last few months — and tells you whether to keep watching or call the vet.
Gentle reminders
Reminders that know your dog’s rhythm.
The classic 8 AM and 6 PM reminders work just fine — but Koiru also notices when walks get shorter than usual, or when feeding has drifted later. Only when something actually changes.
Max’s eating rhythm seems to have changed
The last few days, feeding has been later than usual. Want to take a look together?
Tassutulkki
When something worries you, you don’t have to sit with it alone.
Tassutulkki helps you make sense of the situation. It looks at your dog’s own history and gives a measured read on whether things look ordinary or worth a closer look.
Four possible directions
Nothing obvious to worry about
Keep an eye out as usual.
Keep an eye on it
Log what you see, and let’s check again in the next few days.
Might be worth showing a vet
In the next few days — not urgent.
Contact a vet today
Call the vet today. The on-call clinic if there is one nearby.
Tassutulkki does not replace a vet’s assessment.
Family
One view for the whole family.
When your partner feeds the dog, you see it right away. When the kids take them out for a walk, that shows up too. No more wondering whether the dog has been fed.

FAQ
Good questions, straight answers.
Does Tassutulkki replace a vet?
No. Tassutulkki helps you sense whether it’s time to see the vet, or whether you can wait a little. The diagnosis is always the vet’s job. If you’re worried, just give them a call.
Is Koiru free?
The diary, family sharing and reminders are free — and they’ll stay that way. Premium adds Tassutulkki and the longer history of your dog’s days.
What information do you store?
Only what you log yourself: entries, photos and the basics about your dog. Data is stored in the EU, and you can delete your account whenever.
Does Koiru work for households with multiple dogs?
Yes. With Premium you can add as many dogs as you have — each with their own diary and their own reminders.
What does "Tassutulkki compares against history" mean?
Tassutulkki looks at whether something similar has happened to your dog before, and what helped then. So the answer is rooted in your dog’s own life — not just generic advice.
