One tool. Every knob
that matters.

A recall works because the sound never changes. Yip gives you that consistency, then hands you the whole toolbox: a whistle tunable to the hertz, a true recorded clicker, and cues authored to the millisecond — with free general guides on the side. The multi-tool of training sound, honestly loud enough and never louder.

Cues, not just tones

Build the cue once.
It never drifts.

"Three pips" or "one long blast" — authored once, tone and gap timed to the millisecond, replayed sample-accurately forever. Record a whistle MOVE by how you play the on-screen whistle and it becomes a cue like any other.

Touch and slide — up is higher

The four whistle archetypes: field pip — sharp, focused, far-reaching; trial steady — steady, consistent, clear; pea trill — high pitch, light and quick; shepherd's lip — warm, rich tone that carries far

On your wrist

Fire from the field,
hands completely full.

The Apple Watch quickdial arms one cue and fires it with a tap — or the Double Tap pinch on supported watches. The clicker rides along, with an experimental gesture-cue slot of its own.

Training that starts where your dog is

One question.
Then a plan.

Clicker first, whistle first, or just match the whistle your dog already knows. Short staged sessions built on positive reinforcement, honest progress, and advancement rules stated in plain words.

Built to be tuned

Every dog hears differently.
So everything adjusts.

A short A/B listen test helps you find the pitch your dog responds to. Three tuner controls — focused scale, fine fader, spinning dial — dial it to the hertz. Patterns open in a full editor. And every dog keeps its own pitch, whistle, level, cues, and voice.

Honest by design

Phones can't do ultrasonic.
So Yip never pretends to.

It works in the band dogs hear most keenly — the same range traditional field whistles have used for a century — shows exactly what your device can produce, and caps output at a safe level you can't exceed.

NO ACCOUNT · NO ADS · NO TRACKING · NO INTERNET NEEDED

Kind by design

A whistle is a promise,
not a punishment.

Dogs hear far more than we do — quieter sounds, higher sounds, from further away. That is why Yip caps its loudness, defaults conservative, and teaches only reward-based training: the cue predicts something good, every time. Yip is built for training your own dog, kindly. It is not a deterrent, not a tease, and no fun to point at an animal that never asked to play.

Questions answered plainly.

Why can't I hear some frequencies?

Higher frequencies are harder for people to hear. Yip only offers what your device speaker can actually produce.

Is the volume safe for my dog?

Output is capped at a safe level that cannot be exceeded. Never play sustained tones close to a dog's ear.

Where is my data?

On your device. Yip collects nothing — no account, no analytics, no tracking. See the privacy policy.
