Dog Whistle App: Whistlo
Dog Training, Clicker & Recall
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
The whistle your dog actually hears, a pro clicker, and step-by-step training, so it finally comes back, stops barking, and listens, in five minutes a day.
Does your dog just not listen to you?
You call and call, and it keeps sniffing the grass like you are not even there. The recall you practiced falls apart the moment something more interesting shows up. If walks have started to feel like a fight you keep losing, here is the good news: your dog is not being stubborn, and you are not a bad owner. Your voice changes with your mood, so in a loud, exciting moment it just blends into the background. Your dog is not ignoring you on purpose. It simply never learned one signal it can always pick out.
Whistlo gives it that signal. A whistle sounds exactly the same every time, cuts right through the distractions, and carries much farther than your voice. That is why working dogs have been trained with a whistle for over two hundred years. Pair that one clear sound with a reward at the right moment, and the dog that "never listens" starts coming back to you, from the very first day.
Whistlo helps you get your dog to come back, stop the barking, and finally understand each other, in about five minutes a day. No yelling, no choke chains, no expensive classes. Just the tools a real trainer uses, right in your pocket, for the moments that matter most.
How Whistlo helps:
FIND THE SOUND YOUR DOG ACTUALLY HEARS
A full range of whistle frequencies and patterns, from a gentle recall beep up into the ultrasonic. Find the exact tone your dog reacts to, even in a busy park.
REWARD THE PERFECT MOMENT
A precise clicker marks the instant your dog gets it right, so it knows exactly what earned the treat. Loud mode cuts through outdoor noise, and a flash pairs the mark for dogs that respond to light.
TRAIN COMMANDS STEP BY STEP
Come, Sit, Stay, Quiet, Heel and more, each broken into short, guided steps with the right whistle cue built in. No guessing what to do next.
WATCH IT GO FROM IGNORING TO LISTENING
Log a session in seconds and see streaks, command mastery, and a training calendar fill in. The proof your dog is really changing, week by week.
MADE FOR YOUR DOG
Puppy or senior, retriever or rescue, set up a profile in under a minute and get a plan shaped around the things it actually struggles with.
Your dog's profile and progress stay on your device. Whistlo has no accounts and never sells your information.
Training is not about being loud. It is about being clear, once, in a way your dog can always understand, and Whistlo makes that easy to start today.
