iOS app — just your iPhone's camera

Watch over the little waves
of your pet's sleep.

MikaRipple is an iOS app that reads the gentle rise and fall of your sleeping pet's belly through the camera and records their sleeping respiratory rate. Small daily records become the moment you notice something has changed.

Why sleeping breaths

Why the breathing rate during sleep?

For cats and dogs with heart concerns, recording the sleeping respiratory rate every day is valued in veterinary care. It is the quiet signal of a family member who cannot tell you in words.

01

The steadiest baseline there is

Breathing during sleep is least affected by excitement or activity, which makes it ideal for day-to-day comparison. That is exactly why daily records matter.

02

Change shows up in the numbers

Breathing that stays faster than usual is a widely known sign that it may be time to see a veterinarian. Knowing your pet's normal is what gives you the power to notice.

03

Records change the conversation

With "since when, and how much" written down in numbers, you can tell your veterinarian exactly what happened. MikaRipple builds records you can show at the clinic as they are.

Features

What it does

Measure without touching

Just point your iPhone at your sleeping pet. The app analyzes the tiny movements of the belly and measures the respiratory rate in 30–60 seconds — without waking anyone up.

Manual counting, too

You can also count by tapping the screen with each breath. When the camera can't get a good view, your records don't have to stop.

Not just cats and dogs

If you can see the chest or belly rise and fall as they breathe, you can track them — whatever the species. Cats and dogs, of course, but others too: give each pet a profile (photo, species, birthday, theme color, threshold) and keep watch over your whole family's "today" on a single dashboard, even in multi-pet homes.

Thresholds you can see at a glance

Set a threshold for each pet; days that exceed it appear as red dots on the graph. The dashboard shows everyone's "normal / attention" status in one look.

Notice changes from each pet's "normal"

Beyond a fixed threshold, the app watches each pet's usual range and gently flags when their breathing trends higher than normal — helping you notice early while avoiding needless alarms.

A trend graph that keeps every value

Because daily changes are what matter, nothing is smoothed into averages. Pick a year and scroll through your raw records, day by day.

Emergency contacts, ready when it counts

Save your vet or animal hospital in the app. Tap a phone number to call, tap an address to open Maps. Add as many contacts as you like, so you can reach help fast when it matters most.

A PDF report for your veterinarian

Generate an A4 landscape report with statistics and graphs for any period — print-friendly, ready to hand to your vet at the clinic.

Share the same records with your family

Just show a QR code and the same records appear on your family's iPhone. Whoever takes the measurement, both sides stay up to date — no more "did you already measure today?" No account needed; it travels through your own iCloud.

Your data belongs to you

No account, no ads, no tracking. Video analysis happens entirely on your iPhone and no video ever leaves it. Records are stored on your device, and only when you start sharing with family do they travel through your own iCloud to your family's devices. The developer cannot see their contents.

How to use

Three simple steps

Register your pet

Set a name, a photo, and a threshold. We recommend deciding the threshold together with your veterinarian. Multiple pets are supported.

Measure gently while they sleep

Prop up your iPhone and align the chest–belly area with the guide frame. A deep sleep gives the cleanest measurement.

Turn daily records into watchfulness

Review your records on the graph, and if something looks off, talk to your vet early — with the PDF report in hand.

Our story

About the name MikaRipple

Mikan, the developer's beloved cat
"Have you noticed any changes recently — like faster breathing?"

It was supposed to be a routine checkup. That day, the developer was asked this question by the veterinarian. His beloved cat Mikan, who lives with heart disease, had gotten worse: she needed an oxygen chamber, and might need to be hospitalized. He had been closer to her than anyone, every single day — and he hadn't noticed any change at all. "If only I had watched her properly every day." That regret is where this app began.

Mika comes from Mikan, his beloved cat. Ripple comes from the waves of breath that cross a sleeping belly.

Count the small waves that quietly rise and fall — today, and every day — and keep them. So that you can be among the first to notice when a beloved family member is suffering. MikaRipple was born to make that regret one less.

MikaRipple is not a medical or diagnostic device. Measurements are reference information for daily record-keeping. The app is not intended to diagnose, treat, or prevent any disease — always consult your veterinarian about your pet's health.
