YipDogWhistle
The training whistle that sounds the same every time.
Dogs don't come back for shouting; they come back for a signal they know cold. Yip turns your iPhone into a programmable training whistle — the consistency a brass whistle promises, plus the things brass can't do.
What's inside
Build "three pips" or "one long blast" once; Yip replays it exactly, every time. Record a whistle move by how you play the on-screen whistle and it becomes a cue like any other.
Answer one question and Yip lays out the route: clicker first, whistle first, or just match the whistle your dog already knows. Short staged sessions, honest progress, advancement rules stated in plain words.
An actual recorded trainer's clicker — press for click, lift for clack. Record your own clicker's true voice if you prefer it.
A short listen test finds the frequency your dog notices; every dog keeps its own pitch, whistle, and cues.
Fire your cues from your wrist, hands full.
Honest by design. Phones can't produce true ultrasonic sound — and neither can Yip, so it never pretends to. It works in the band dogs hear most keenly, shows exactly what your device can produce, and caps output at a safe level you can't exceed. No account. No ads. No tracking. Works entirely offline.

Why can't I hear some frequencies?
Higher frequencies are harder for people to hear. Yip only offers the range your device speaker can actually produce, and shows that range honestly.
Is the volume safe for my dog?
Output is capped at a safe level that cannot be exceeded, and defaults are conservative. Never play sustained tones close to a dog's ear.
Where is my data?
On your device. Yip collects nothing — see the privacy policy.
Training results vary with the dog, the handler, and the work put in — no outcome is guaranteed. See the terms & disclaimers.
