Rest your hand on the trackpad. Real haptics at 25.75 Hz, the measured pitch of an actual cat. Not a sound file. A feeling.
macOS 14+. Any MacBook since 2015, or a Magic Trackpad 2. The purr is free forever.
See it, then feel it
Scientifically accurate
Rest your hand and it usually purrs. Sometimes it looks at you and decides not to, then sulks for a minute. We modeled that too, because you own a cat and you know.
Six cats included
Each one is a different breath, drawn below exactly as your palm will feel it.
The headline feature
Hold the mic near your cat for ten seconds. PurrPad reads the pitch and the restlessness of the purr, on your Mac, nothing uploaded, and teaches your trackpad to purr like her. Your cat lives in your laptop now. She pays no rent there either.
Pricing
For the nerds at the back
The wellness angle
For real cats, that is. Researchers and veterinarians have associated purr exposure with a calmer nervous system, lower blood pressure and cortisol, and endorphin release, and the vibration band overlaps frequencies studied in human medicine for bone and tissue stimulation.
Now the part our imaginary lawyer purrs loudest about: those findings are about real cats, who are warm, alive, and love you conditionally. PurrPad is a trackpad doing an impression of one. It is not a medical device, it treats nothing, and it has never healed a bone. It does feel lovely, and feeling lovely is not nothing.

What we do not do
PurrPad has no analytics, no telemetry, no crash reporting, no account, and no server that knows you exist. Your cats, your recordings and your shelf live in a file on your Mac and nowhere else.
You do not have to take our word for it: point Little Snitch (or any firewall) at PurrPad and watch it sit there saying nothing. That is the whole design. A cat on your trackpad is not a reason for anybody to build a profile of you.
Which does mean we learn nothing unless you tell us, so please do: tell us what your cat thinks. Complaints welcome, photos of the cat preferred.
Fair questions
No. It taps the same haptic engine every click of your trackpad already uses, at the strength of a normal click, just rhythmically. Battery cost rounds to zero.
Honestly: yes. The purr drives the trackpad through a private macOS interface, and a future update could close it. If that ever happens and we cannot fix it, ask for a refund and you will get one, no questions. We price it like something mortal, because it is.
Dogs do not purr. We looked into it. The trackpad can do a heartbeat, though, so never say never.
Working as intended.
Nothing leaves your Mac. The recording is analyzed on-device, turned into nine numbers, and deleted. We never hear your cat, which is our loss.
Only to ask whether a newer version exists, and only if you leave that switch on. No analytics, no accounts, no crash reporting. Your recordings are analysed on your Mac and deleted; nothing is uploaded.
Any Mac with a Force Touch trackpad: MacBooks from 2015 onward, or a Magic Trackpad 2 and newer on desktops. Apple Silicon and Intel both.
